this was a great video! I wish I had the confidence to do it all myself lol

[@33milegarage34]

Thanks for the comment. If you want take one part at a time. Hit me up with any questions.

[@benjamintresham9649]

Make sure you use the CORRECT radiator cap. Partial pressure cap NOT a normal one that has the spring loaded bleeding valve

[@33milegarage34]

Good point and easily overlooked! Thanks for the comment and watching!

[@benjamintresham9649]

All good 👍🏻 I have two TJ wranglers here in Australia and we can get some HOT summer weather so the cooling system is my number one ☝️

[@RadioReprised]

I used a Hayden heavy clutch, 195 thermostat and a Griffin 3'' Rad...She sits on 190-195 in 100 degrees. I don't like it at 210 plus my A/C works better.

[@33milegarage34]

I agree with you, Haley’s Jeep sits at 210 and I always felt it was to hot. I like your set up running at 190-195!!!! Thanks for watching

[@carolynruger-rb4kj]

They actually read 210 from 190-234 so if your reading 190-195 you're running too cold and outside manufacturer's specs. Trying to one-up the design engineers will ALWAYS bite you in the butt eventually. Run it the way it was DESIGNED to run. You'd have their job(s) if you knew more about it than they do.@@33milegarage34

[@rickreese5794]

210 IS TOO HOT 😊

[@SanshokuCustoms]

And the angry grill is helping to overheat

[@33milegarage34]

ILOL. Show the angry grill some love. Thanks for watching and the comment.

[@SanshokuCustoms]

@@33milegarage34 believe me, those things restrict the air flow to the engine bay causing the cooling system to work more than normal…

U ain't lying 🎉 😂​@@SanshokuCustoms

I keep having overheating in my 03 jeep tj. I replaced the radiator thermostat water pump clutch fan head casket. I checked all the relay and its still overheated. I realized after i installed topfire style front grille i start to get overheat. I took it off, everything went back to normal. (It was not enough air flow to the radiator from the peice of crap i installed)

[@33milegarage34]

Yeah. I’m sure that was frustrating! I’m not a fan of the aftermarket grills but It’s my daughters Jeep and she likes it, and it doesn’t really block air flow. Thanks for commenting and watching

[@jonc2914]

New radiator, new clutch fan, new thermostat, new water pump, new pullies and belt. Everything was fine, but then i got my ac fixed(new condenser) and i overheat when stopped at idle randomly(doesnt happens all the time) while driving, its fine even with ac full blast. No idea what the deal is... any ideas?

[@33milegarage34]

Wow you replaced everything. Great question…The only 2 things that come to mind 1 Is the fan shroud damaged or has a large gap from the shroud to the radiator 2 with all the radiators on the market a good quality radiator is king.

[@jonc2914]

​@@33milegarage34update. My new radiator blew today. After only 10 months of being installed. Cracked across the top in the same exact location as the old one. Coolant exploded and went everywhere and it happened when I turned off the car. just like 10 months ago. No idea why this happened. Going with all aluminum rad this time

[@tillybilly8781]

i had the same problem aftermaket rad had a hair line crack on the top after about a year so i went with the mishimoto alumimum rad good so far

[@JasterMereel421]

Every single video that I have watched about replacing the water pump, they all forget to put a bucket under it before taking it off so coolant spills onto the ground. When I replaced my water pump, I also followed those instructions.

[@33milegarage34]

Yeah. The worst part is the bucket was only a few feet away under the radiator. Thanks for the laugh!

[@2times2is4]

I put the angry bird on mine and the temperature went up 15° . I have a winch and there's no air flow now. Took it off and I am back at 175°

[@33milegarage34]

Wow 175 degrees is super low for 4.0L that’s great. Thanks for watching and the comment!

[@2times2is4]

@@33milegarage34 It's a 2.4. Still low. I put a nice aluminum radiator in it. Much better.

[@RedPaw715]

Great video! Is there a tool I can purchase for the fan removal? Thnx!

[@33milegarage34]

Yes they sell a tool. I just looked up a Clutch fan removal tool on EBAY for about $25. Most tools come with a few sizes. If I remember correctly the nut is 36mm and the other portion of the tool needs to span 2.25”” or 57.1mm for the water pump pulley bolts. (most tools have a large slot to accommodate multiple sizes) if the nut is seized on and you need to use force to break it free the cheaper tools will bend up. Thanks for watching!

[@JasterMereel421]

To remove the fan, an 18" crescent wrench or 18" pipe wrench on the giant nut works. Take a 1/2" breaker bar, put it into the tensioner, push that to the passanger side, and then whack the wrench with a hammer. As for removing the fan clutch O'Reillys will loan you a part for 48 hours to remove it.

[@jorgezuni2818]

And for those of us that did the Electric Fan And eliminated the mechanical Fan .. what suggestions when over heating would you consider to be ?

[@33milegarage34]

Diameter of the fan and how it seals against the radiator are big factors. The fans need to have a shroud that seals tight and covers 80% of the radiator surface. A cheap fan with a little shroud will not keep it cool. Thanks for watching

[@rickreese5794]

My 06 runs at 205-210😮😢

[@33milegarage34]

205 for a 4.0l is great! Thanks for watching

[@33milegarage34]

205 is great for 4.0l. Thanks for watching
