New cold air intake, engine overheated.

I have a 4cyl, and I just put an AEM Brute Force cold air intake on it. I drove 3 hours on the interstate (i know dumb) and when i pulled up the engine overheated when I turned off the jeep. Went outside saw the splash from the radiator cap on the under side off the hood. So i let it cool down for a while, put water in it, later drove like 2 miles, stopped looked and it was leaking (not that much but was def a quick spill) again. Drove back and didnt leak as much when I parked.

Do u think it cold be a bad rad? Temp Gauge?

I am kinda stuck need some help.

Thanks

Depends where you saw the leak coming from. I had a bad hose and it didnt leak until the engine got some heat in it and the cooling system pressureized. Once it got pressure it was a fine spray coming out of it. top it off with water, let her run and you should beable to track it down

Thanks, I looked on top of the radiator and I have always had some residue on top but it has never done anything like this before.
Thanks again

The OE radiator has an aluminum core with a plastic top and bottom that is only crimped to the core. A leak where it is crimped together is common after a while but unlike most other radiators, it can't be repaired well enough to keep it from leaking again in the future. If indeed it's the radiator leaking and not just a bad radiator cap or something else, you're better off replacing the radiator. If you do it yourself, make sure to mix distilled water with the antifreeze to make your 50:50 mixture. Water from your hose is high in mineral content which will cause calcium (hard water) deposits to start forming inside the radiator which will eventually start clogging it.

So take a good close look once it cools to know for sure if it's the radiator leaking where it is crimped together, a bad radiator cap, or something else.

I looked at the top, the plastic part on top of the radiator. I saw some bubbling on plastic right were the aluminum is crimped on. So that is the problem. Is that a hard fix?

Hard to fix...nope...new radiator. Easy to install. Just don't get a factory replacement. Go with a all metal radaitor to not have this problem again.

I replaced the radiator. Not hard, could def do another one now under an hour. Once you have done one, you can fly through the next one. Thanks for all the advice guys.

How do you like your AEM intake do you notice any greater MPG or power?
