I can't pinpoint the leak right now due to wet paint on the hood. But it just started leaking overnight from the passenger side, I can only see it dripping off the factory drag hook. After not driving it for hours. Does anyone know if those radiator stop leaks work? And 2, is there common places that they leak and ways to fix them?

 

DO NOT use radiator stop leak. I used in my truck 3 weeks after i had a clogged heater core and i had to spend hours flushing the system the heater core everything. Do it once do it right just replace it if its leaking.

 

I have narrowed it down, it is coming out of the radiator itself unless there is a hidden hose under the radiator itself. Looks like I may need to replace the whole thing. Won't know till I drain her and pull her

 

ixnay on stop leak. It is bad news.

If the radiator is leaking, REPLACE it. Repairs are something that was done in days gone by. A new one is between $100 and $250 dollars. I like the all metal. Go 2 row for daily drivers. 3 row for wheeling vehicles.

And while you're at it, review all other cooling system hardware. 195 degree Jeep stat, water pump, fan clutch, hoses, serpentine belt that powers pump.

There is NO better money, than that spent on cooling system maintenance.

 

X2!

 

I had a leak in mine a couple years back and replaced it. A common area for leaks is at the plastic end cap.

 

At the pitcock valve?

 

I agree, replace it! I made the stupid mistake of having one repaired a couple of years back, and didn't flush it out well enough afterward, corosion got in and cloged the heater core etc... Replace now, it doesn't cost that much more to buy a new radiator and it will save heart ache in the long run.

 

Check that your petcock valve hasn't loosend up on you first, then pressure test your system before you listen to the others and start yankin shi.t out. The pressure test will show you if and where you have a leak. GL

 

Good point. Mine wasn't leaking a drop but it's only a matter of time with a 13 year old plastic tank rad. My coolant was black so figured someone had already BTDT.

Replaced w/copper core/brass tank after flushing. Problem solved.
