In this video I helped a friend replace a thermostat in their 1999 Mercury Marquis. This process should work for many Mercury vehicles with the V8.

I have to replace my thermostat on my 99 grand marquis gs so this was very helpful! I’m going to do it tomorrow! I will let you know how I make out and I will be using your video as an instructional step by step. Thanks bro
you are welcome.
Thank you so much brother straightforward to the point accurate information and no rambling on about nonsense thank you so greatly appreciated God bless you and may you be prosperous in your endeavors

Totally used this video to replace my thermostat and housing by myself!! Thanks!
+Faith Riquelme you are welcome
Thanks Robert, I should have looked at your Video before I changed the thermostat, I put the SEAL on the bottom of the thermostat instead of on the top. Thanks Robert for you video you did a great job.
Thanks for watching.
Thank you so much I was able to fix my car myself women power.Yeah
Very nice. Thanks for watching.
Hell yea Mary
Great video bro I have a 98 grand marquis and I'm going to try it myself!!!
Hope all goes smooth.
You make fixing a problem a happy thing! Thank you!! :)
You are welcome
I have a 2003 Crown Victoria. The engine set up is identical to this car. I rarely drive it. 3 nights ago I let it idle in the driveway for 25 minutes. I normally try to do that once a week if I haven't driven it. Well it ran hot. Just last night I crunk it up to see if it would start to over heat are see if there was leaks. Well there was no problems at all and it ran for 35 minutes and the last 10 was with the ac on. The fan works so I'm guess when it ran hot the other night that was a sign of the thermostat starting to fail. Well as cheap as a thermostat is and this video which makes it look so easy I will be surely trying this on my car.
Sounds reasonable. I would change that as well. However, I don't agree with starting a vehicle just to let it run. Drive it or leave it parked.
Thank you. This video saved me serious money from going to the dealership service.
Glad it helped
Gracias amigo. Seems very simple ima give it a shot today.
Yes, easy.
Thanks for your content 🙏 just what needed too know about this project
thanks for watching.
thank you very much for her help I wish there more people like you wonder if you can show how to do a spark plug change 4 just so the people I don't know will l
learn
+Peter I'll try to remember to do that, what year?
I forgot to mention - it's a very good idea to replace the cap on the coolant bottle on these Fords. Most use a 16lb cap, costs something like $7. I pressure test every radiator/coolant bottle cap I come across when I'm servicing vehicles and I've found these Fords have a very high failure rate on the caps (usually won't hold anywhere near 16psi).
+AKJeeper ouch! It was releasing fluid so I'll tell them to replace it.
This is what I needed to no and i do work on my own car thanks to you my brother one love
Glad I could help
Video helped a bunch, heat is back on! Thanks so much!

Awesome! Thanks for watching.
Thanks alot robertdiy now I can fix my car and save myself a couple hundred bucks.
Awesome!
I have a question I replaced my valve covers and my intake manifold with a dorman brand intake the car was running fine now two days later the engine idles louder and requires me to hit the pedal a bit harder and the car sounds louder during acceleration. Is this because I'm using a 180 t stat instead of the 195 or do you think the intake is faulty I don't see any coolant leaking anywhere from back portion of the motor so I'm not sure what's going on thank you.
Cool thank you Robert, my 2000 Crown Vic. the heater is slow to heat & there was no pressure on the top radiator hose when I squeezed it when it was hot. Hope it's the thermostat? The heater core was replaced several years ago.
How is the level in the radiator?
@@RobertDIY you're absolutely moving in the right direction... there is a leak. I topped it off & have full pressure then saw a small leak when the car is shut off.
Thank you and God Bless
🙏🏾🙌🏾
Nice video as always Mr. Robert!
Thanks.
Have a 2001 Towncar with same engine. Thanks for posting
You are welcome.
I like this guy! Thanks for the help!
You are welcome.
Thanks Robert
You are welcome.
Thank you for making this video. You showed detailed step by step and that's what I needed. So thank you. Also do you think it's best to use the hose clamps that you squeeze together with needle nose pliers or the screw type? Thank you
Either works fine. I like the worm clamps that you use a screw driver to secure but a lot of hoses are damaged with those.
Thank you for the information. Really did help.
you are welcome.
Great video quick useful and straight to the point

Good Job, thanks !!!!
You are welcome
2:40 my thermostat housing is glued. As you pointed out. What do you suggest or advice to remove it without problems Sr?
take your time and peal it apart.
Great and concise video! How long should the car take to reach normal operating temperature, from a cold start on a normal warm day? What degree thermostat did you use in the video? Have a blessed day
depends on the engine design. Usually within 5 minutes or 3 miles.
Most thermostats are 190 degrees.
Looks easy enough.
Yes it is.
Appears a coolant change was in order, lots of rust. Owner didn't replace antifreeze last time when top hose blew, that is a newer top hose.
I don't know. It looked nasty.
Thank you. Know I am going to do my own
Cool
I ain't got time for that.
Good vid.
+motordar thanks for watching.
I changed mine a month ago...I only lost about about 2 tablespoons of antifreeze when I took the housing off....I replaced the thermostat because of codes saying car was running too cold. it was 40 outside and the water temp never got above 160...after it never got above 190 with it being high 90's...most of the time running it runs a 189...it only took about 10 minutes...most auto stores wanted a 130 bucks to change it...
Good deal.
Very nice
Thanks for watching
Very helpful video
😎great teaching,I needed this. 05 Mercury Grand Marquis. They wasn't nice to it. So I'm Dr.Frankinstine to bring life back to it. 😂😉
hope it works out for you.
Very important I'm havin alil antifreeze leaking out
Thanks 👍
Welcome 👍
Thanks
No problem
question.. the hose that is connected behind my water pump is leaking, is water pump bad or is it the hose? it leaks coolant and causes my car to overheat, I currently have a 2002 grand marquis
+Ruben Martinez probably the hose.
Myballsitchsomethingfierce just take the alternator off and you're able to get to the hose cut it off and run a new hose the only way you can bypass without taking off the intake and all the extra work
does a 2001 annd 2002. fit
What's the hose connect to?
Thanks , good video.
You are welcome
Thanks buddy
You are welcome
Good video Robert just wondering what is your opinion on the ford 4.6 good engine?
I think so.
Great video. Thanks.
You are welcome.
Why is there only a reservoir cap with no pressure ratings on it is there a different kind of cap on the radiator I can’t find it
Because the system is not supposed to be pressurized.
I did my car The Same model but l didn't drain the radiator. Just left the hose on. And change it.
Nice
How did you get the fan to kick on when you were testing it
Let it run for a long time.
Hey i have a 2002 grand marquis gs and i just replaced radiator because it had a leak , i didn’t replace thermostat but it goes above the middle line but not on hot should i replace thermostat as well ?
I have no idea. Is it bad?
What’s the part number for the metal gasket? I changed mine but it still leaks. AutoZone doesn’t have it?
I have no idea. You may want to check with the dealer or on a parts website like Parts Geek.
Hi Mr. Robert!
What's up?
Man thank you so much!!!
Any time
Hi u doing and just to say nice video brother. I have a Ford grand marquis 2000 and the people did a engine test on the car and I wanna kw what a p1285 or p1299?
I have no idea. Have you tried Googling?
How to I replace fuel door button on door ? Mines broke so now i have to open fuel door from truck
I have no idea.
Why don’t they sell the housing gasket?
Someone probably sells them. 🤔
Often these cars have cracked intake manifolds because they make them out of plastic.
Yikes!
91jchevy87ec1 the 99s dont have the cracking problem. its the 96-98s
Would it be the same process on a 92
I have no idea
The procedure is exactly the same for a '92 4.6-liter Panther engine.
Can u make a video to show how to replace the heater hose from the heater core to the engine
I'll try to remember to do that. Did you watch the heater core video?
ruclips.net/video/Qdk4WFpQ7gs/видео.html
So if your engine starts overheating while driving it over 70mph, this is the main go to solution to fix it?
If it's bad.
@@RobertDIY do i have to bleed the system of the coolant?
@@prod.bylvwlee NO.
Thank you!
+Ken Elliston you are welcome
What does the thermostat housing connect to? The black part on the bottom is leaking
Cylinder head.
It's actually the intake manifold
Will it get air in system when replacing thermostat without bleeding it?
I would think so.
@@RobertDIY thanks for the reply
Replacing mine & someone has glued it down. Idk how to get it off. Help please.
you'll have to pry it off.
hi it was very helpful, however when I replaced it I noticed the bottom part of that housing seal seems have broke or came unsealed and is slowly leaking, so you can better understand where about 4 inches from where the thermostat is where it connect to the top part of the engine, is that an easy fix where I just take apart and reseal?
Best to give me a time stamp or text me a picture.
Holy shit Eazy E is still alive
Huh?
But where is Biggy and Tupac !??
How do you know,if your fans blowing properly? I can run my a.c. all I want till,I go up a hill on the interstate and on extremely hot days it trys to over heat and I'm thinking it's the fan cuz I have no issues,anywhere else also its a 97 marquis
The fan should be on ALL THE TIME when you run the AC.
What do you do if the housing is stuck ?
work it off.
Peace Robert, I'm having the
same type problem with overheating. I'm no mechanic but ok with hands on learning. My fan seems to have a short either in the plug or fan socket. I will do the thermostat thing I seen here first but can you suggest what best if that's not the problem? I have the same car, make and model
ruclips.net/video/BtdifArSU3Q/видео.html
Do I have to blead the system after
Yes.
Robert, I have a question that I hope you can answer. 5 days ago my 2009 Grand Marquis overheated. The engine light came on, the windshield fogged up and steam started coming out of the hood. I limped the car home, half a mile, opened the hood, and let it cool. The left side of the engine was soaked. After it cooled I added about 2 quarts of water. Took it to my mechanic, and he did a pressure check and found no leaks. Still, I'm heading to Florida in a couple days, pulling an 8X10 utility trailer. WHAT could have caused this leak? I was hoping it was a simple hose break, but I guess not. Could it be the thermostat? And where did the water come from all over the engine? Thanks for your response, Robert. Paul
There is no way for me to tell without looking at it. I can't see it from here. If the vehicle engine overheated, you need to determine why??? Then fix that so that it won't force coolant out of whatever leaked during the last overheating incident.
ruclips.net/video/BtdifArSU3Q/видео.html
do yoy know how to fix the temperature gauge inside the car or are you not that great with electrical
thx
Huh? Who said something was wrong with the temp gauge?
Let me ask you Robert I have a 2000 Ford crown Victoria lx I am having the same issues with the Thermostat in order to replace the parts is it located in the same area as your 99 crown marquis? Thank you for your video it was very informative keep up the good work I learned allot. 😁👍
Probably. Have you looked?
The 2000 Crown Vic and the 1999 Grand Marquis have exactly the same type of Thermostat Housing -- located in exactly the same place.
Correct Thermostat is : MOTORAD #5228 -195 JV -- Holds temp at 192 F to 198 F
Correct Gasket is: MOTORCRAFT #RG-571 -- Gasket goes ON TOP of thermostat.
fan would , would have kicked on if you would have turned on the normal air conditioning or even the heater that's how a lot of cars and up overheating because they leave their cars outside and let it idle and cool at the same time it works for new newer vehicles but not the older ones
+Peter should also come on when the car starts getting hot.
Hey brotha, I changed my thermostat like u showed in the video so that's new, but my temp gauge is rising still and the ac blows hot air, and yesterday I was at D.Q. in drive thru and the temp went almost to top I live 3 blocks away had my lil boy or would have walked, anyways I opened the hood and the radiator hose was swelled up, Any ideas?? It's a 99 Marquis and I'm sure water pump/ radiator are original.. Thanks Brotha

Do really need to drain your antifreeze?
🤷🏾♂️
Thanks a million
What's the name of that Part right after u put the thermostat with the gasket on ???
What is the time stamp?
@@RobertDIY time stamp ? What is or where is that ?
@@RobertDIY how many gallons u think it takes to do a drain and refill...
Should've let the one I'm working on cool down more...
🎉
ouch
my cooling fan wont turn off while my 2004 marquis is running
Is the AC on?
My 93 ran hot now it want start
Ouch
About how much does this cost if you take it to a mechanic for this car?
