$25 DIY Radiator Spray

- This week we install a very inexpensive misting system to cool the radiator on those hot, long climbs. We chose a budget system for only $18 on Amazon.

Hi Juan and Michelle,
Nice job on the misters!
So, a couple of things:
First; about 30 years ago I met a guy in a campground who had his 4106 for about 10 years. He told me it will run 100 degrees over ambient temperature. He was right, on normal driving (not hills) the engine runs almost exactly 100 degrees over outside air temps with the automatic transmission.
Second, I noticed your radiator is not sealed against the cover grill, especially around the top of the radiator where there is a really big gap. Because of the design of these buses with them sucking air from the side of the bus in the back corner, rather than ramming it in through a front grill mount, it is really important that the radiator ONLY draw air from outside. Without being sealed, it will recirculate a good amount of hot air that has already passed through the radiator, thus using pre-heated air to try to cool the engine. This is especially problematic when climbing hills because the engine is running at high rpms as is the fan and there is less fresh outside air being drawn in because of lower speeds. When I close the radiator cover, it can only draw air through the fins from outside because it is sealed away from the engine compartment. (I'll take a couple of pics and show you mine.)
You might notice some newer MCIs have a mud-flap type thing that hangs below the length of the radiator. They put that there to prevent hot air being recirculated under the bus and back up through the radiator on those buses.
That seems like a pretty ingenious idea and fix for when you need it. And congrats to Dom on his graduation!
High tech swamp cooler... This is probably the best use for it I have seen.
The previous owner of my bus put a second radiator up front where the spare tire goes. It has a fan on it and it's actuated by a switch on the dash
Yep, sunset points always fun in the summertime. Especially if you get stuck behind a truck. Hope that works out for you well.
A simple but elegant solution...nicely done!
thats a great solution Juan, I'm glad everything worked out for you guys. stay safe and see you on the next one 👍
I used the same misters on my rig. I put 6 around the intake side of the shroud and controlled the valve with a wireless remote. It helped a bit.
Yes, this will help. And down shift early to keep the max RPM, as you did.
We did this on our race car. Used the washer bottle. It worked great.
I your missing some rubber that makes the radiator only get cool air from outside and stops warmed air from the engine bay from wrapping back around and entering the radiator.
Aaahm, my fav channel for my perfectionism fix! ;)
That works well and something I would of never thought of. Cheers.
Great job. I always enjoy watching your modifications and improvements. They are always so neatly done. It will be interesting to see how well this works after you have had a chance to test it more. Cheers!
Ive been wanting to do this to our eagle for some time now. Our Eagle has only come close to overheating one time while driving through AZ going up a long stretch. I like using Emylo remote switches, so maybe I’ll try that to avoid running wire from dash to engine.
Thanks for sharing
Hey thanks guys - ours is only a problem in AZ as well - I just view it as cheap insurance.
Super cool!
LOL love it
Great idea, always enjoy your videos. Good to see your son helping out.
Great idea!
Hello Juan,
Basic engineering at its best. My only comment is the apparent lack of a check valve to prevent any possible back flow into your potable water system which is where I assume the water is supplied from.
Good idea. Our coach we slow way down. 190 is about it heading up to Denver
Always inventive and interesting 👍
A very good very SIMPLE approach to keeping temps down. I like the idea. Our 102el3 will sit around 205 on a big climb, at which point the compressor for the fan kicks on and drops us back down to 180, then we play the "up/down" game the whole climb. This would probably help a lot with that. I'd also be curious if there was some way to create more airflow over the radiator in general. I've seen some people make "scoops" etc... but it kinda seems pointless being the whole side of the bus is a giant low pressure zone. I thought about e-fans... the ones from our AC system move some SERIOUS air... but not nearly as much as the mechanical fan. Hmm. Thanks for the video and update!
I havent seen or heard of anything like this
I searched RUclips and here you are
How us it holding up ?
I'm in az aswell and the summers are brutal for towing in the mountains
I did this on my RX8 she runs hot in the summer in Phoenix. With the misters I can drop the Temps to spring time engine Temps. For a rotary it will drop to 215 it will get to 240 with out it and the ac struggles.
Luv ya work mate👌🇦🇺
First time saw this idea, cool! Next step, link that to homeassistant, install a temperature activated spray?😁
I've read you can get mineral deposits on the radiator fins if you don't use distilled water
That would make sense if you are in an area with really hard water. We have only really used this like 3 times since we installed it but I will keep an eye out for that! Thank you!
@@BeginningfromthisMorning no idea how much of a problem it could be, but definitely worth watching out for. I did something similar but used an old smaller rv water tank so I could use distilled water...used a second rv water pump to to run it. It helped, but I ended up adding an additional transmission cooler with two 8 inch fans and that has really helped with climbing grades. Might add an additional oil cooler with a thermostat valve for additional insurance some day
@@natesprojects1982 awesome! Our bus did come with a very large transmission cooler with a 16" fan pushing air OUT of the opposite side of the radiator. It helps a TON with transmission heat.
I’m putting this on my coyote 5.0 😂
Great idea, I know Scott would like this or already knows about this trick?
💔Buddy Says Happy Father Days thank you for the good idea 👍
Hey guys,
That looked like a great idea.
Q. Where was the water supply from.
✌️ Peace everyone.
Water supply is just from our main tank

As I’ve said before, love the progress you continue to make on the bus. This is one of my to-do items and I like your Amazon solution. With that I have also learned from reading is that the happy temp-zone for climbing me is 190 degrees maximum as well. Are you running 170 or 180 degree thermostats? I need to replace mine and am planning to run 170’s as I’m in the same part of the US, lots of climbing and descending.
I believe my thermostat is 170 but I am honestly not 100% sure. We live in Arizona so it is very often very hot.
@@BeginningfromthisMorning thanks!
No tranny removals in fram motor rebuilds just a squirter video lol lol I bet you know you can do anything that your bus needs now! Its going to be hard to have another video like that tranny! Man that solar on top was awesome also The only thing that will stop you guys on any job is your selfs! You guys know that now also
Good idea, but have you also checked whether the radiator got wet during the ride, if the airflow goes the other way then it makes no sense.🙂

Hi again, is it a good idea to paint the radiator and mounting brackets to prevent rust? I already saw, for instance at 6.15m, that you do have rust over there. Where do you take the water from, is there a separate tank or is it drinking water?
love the video, hate the music
Any exposure to freezing temps?
We have been caught in freezing temps only a few times.
I am just curious how much water you really use when spraying the radiator.
Not much water. We carry a large amount of water (166 gallons) and we use a Sea Level 2. The most we have ever used was like 2% - so something like 3-4 gallons?
@@BeginningfromthisMorning that is not much at all, definitely the way to go.
Has anyone tried a side scoop?
I have seen a few designs for side scoops - John Mathews commented earlier that I am missing a piece on my bus that should increase the efficiency of the air getting into the radiator. I am curious about this as well.
