- Video highlighting the process of Replacing a Humvee Water Pump.
1993 HMMWV M998 A1, 6.2L
Major thanks to James Justice, the 'Humvee whisperer' for his help and expertise.
Hopefully this video gives others a little courage to attempt this fix themselves. It is definitely a daunting task to think of opening up your humvee and removing the cooling stack and making sure it goes off without a hitch.

Thank you for making this video. I just got my first M998 and was able to replace the water pump following your process. It took me and my 73 year young Father a couple days, but we got it! 😃 thanks again! 👍🏼
SO glad it was helpful :)
A very great job. Very informative for me. Thank you that there are people who make such great videos. Greetings from Germany
Bitteschön!
@@MyHumveeMathilda Dankeschön!
I could also see an issue if you had one of the aftermarket AC units mounted in that stack as well. Te good thing is that once that front end comes off everything is at ones disposal to work on.
What is the maximum temperature indicated by the coolant needle that you have ever reached under effort? Have you ever touched the line/notch next to the middle when overexerting yourself? Thank you
The fan always kicks in when it’s supposed to between 215-220
Great work
Thank you. Learning as I go.
Very helpful. Thank you for sharing
You’re welcome. Check out my other videos too.
@@MyHumveeMathilda I will ty.. subscribed 😎👍
Did you only get leaks around the pump or did you also get leaks coming out of the top hose coming from the radiator during starting it?
From the seal… and the bearing was getting loose as well so it would squirt coolant into the belts and of course the belts would end up flinging it under the hood and spraying it everywhere.
Love your videos...I need to replace my engine fan, do I need to remove the radiator?
Thank you for your kind words 🙏
@@MyHumveeMathilda need to replace my engine fan, do I need to remove the radiator?
@louleone1032 yes. You need to remove the coolant stack. You can do the fan change from underneath and that takes a lot of skill but it’ll take longer. Much longer. It’s a two man job removing your hood and stack btw.
Check my video on changing the water pump.
the trans cooler and radiator is the cooling "stack"?@@MyHumveeMathilda
HI. How often does the pump need to be changed? How many miles must the vehicle have travelled? I would like to understand . Thank you
What model HMMWV do you have? Your videos look like it’s a civilian Hummer or maybe something else.
@@MyHumveeMathilda i have a hummer h1 2004 k series
Well for civilian cars usually 50-60k miles. Sometimes it’s good to do it everytime you swap your timing belts out (gasoline powered cars).
Is yours leaking? If so it’s time to change it out.
@@MyHumveeMathilda no, it doesn't lose. My H1 only has 16500 miles.
In 20 years....16500 miles
Ouch!
That cooling stack removal is a royal pain in the a$$!
It would be nice if they had QD lines for the tranny cooler that self seal.
It really is. And you have to plug up the oil lines or you’ll have a mess on your hands.
Awesome!!! Is there a way you can show the process without the time lapsed?
I just want to see all the components while being remove to get to the water pump.
Thank you.
Al from California.
Not really friend. I shot the videos in time lapse mode. Your best bet is to Inspect the components physically that I showed and go by the process I showed, you should be ok. Quite simply put, put everything back the way you removed it, only in reverse and replace all the hoses and the new parts and gaskets and belts. You should be OK.
No worries, just watched all your videos.
Very nice.( subscribed)
Thank you 🙏
My radiator was leaking , had to install myself. Not fun! Found radiator made of aluminum for less than $300.00 on ebay claimed to have Lifetime Warranty. I have seen original for $1,400.00
is that James Justice? Lol
Yes it is. He lives not too far from me.
@@MyHumveeMathilda 👍very nice person, humvee expert
@@MyHumveeMathilda I live in Virginia. He helped me covert from 4 man soft top to hardtop slant back. Can’t thank him enough.
@@ztcssb3831 oh he’s the best for sure. I was really stressed out when I first got my HMMWV and he’s helped a lot. If he hadn’t checked my hubs last month I’d be driving on the highway with a wheel falling off. Lol.
@@MyHumveeMathilda 😂 take care, have fun with humvee
