Antifreeze leak
 
5.2
Okay so I have a coolant leak, ill drive it about 1000 miles then I have what I think is a high pressure leak the first time it happened it blew antifreeze everywhere all under the truck on inside of the tires aswell I put a pressure tester on it and nothing no leaks changed the lower radiator hose an it stopped next 1000 miles it happened again but not bad at all in thinking its coming from the water pump seal or something and usually it happens when it's really cold out If anyone can give me advise or help that'd be great

Three days ago I fixed a Durango that was doing the same thing. The solution - replacing the bad cooling system cap.

Gharlan1 01-03-2013 09:59 AM

As in the radiator cap? How do you know I it's bad cuz the coolant is coming from the bottom of the truck would that cause it?

RamTech 01-03-2013 10:03 AM

Yeah, the radiator cap (I call it a cooling system cap because not all of them are on the radiator). If you have the correct adapter, you can pressure test it just like the rest of the cooling system. It should hold pressure within 2 psi of its rating and not leak down.

Yeah last time I did it I think it was 16 psi and it stayed the same but when I changed the lower radiator hose it didn't blow as much out as before

Gharlan1 01-03-2013 10:11 AM

Another thing how much is a cap and how do you tell if its bad?

RamTech 01-03-2013 10:16 AM

The pressure test is what tells you if the cap is bad or not. A new one shouldn't run more than $15, give or take.

So just to make sure with the problem I'm having I should do another pressure test ad if it holds steady pressure then I have a bad cap correct

RamTech 01-03-2013 10:31 AM

No, if it doesn't hold pressure within 2 psi of the rating, it's bad.

Gharlan1 01-03-2013 10:37 AM

Yeah that's what I ment if it doesn't
