Hecubus Posted January 29, 2015 Share Posted January 29, 2015 To start, I have an 07 with 150k miles on it. The Head Gaskets were replaced almost 2 years ago. That being said, my car is overheating rapidly once up to operating temperature. Once the temp gets up, I look under the hood and antifreeze is all over the front drivers side of the engine compartment. I cannot find any leaks. I've replaced the Thermostat and Radiator cap. Water Pump was replaced the same time as the Head Gaskets. I'm going to be testing the radiator today with a Radiator Pressure Tester and a Block Tester. When I run the car at normal temperature with the cap off I don't see any bubbles coming up out of the radiator. I'm thinking (dreading) that I'll have to put in another set of head gaskets. Has anyone had the same experience or advice? Link to comment Share on other sites More sharing options...
doobaruGT Posted January 29, 2015 Share Posted January 29, 2015 Check the upper rad hose. The fans are infamous for creating a pinhole and then spraying AF all over the bay.

CapnJack Posted January 29, 2015 Share Posted January 29, 2015 Also check the oil cooler hard pipe on the bottom of the front of the engine. They can also rust and create pinhole leaks. Is it possible that you have an air bubble in your engine from the head/waterpump replacement that is causing your overheating? Link to comment Share on other sites More sharing options...
MrTris Posted January 29, 2015 Share Posted January 29, 2015 How full is your coolant reservoir when this happens? Past the full line? All the way to the top? Link to comment Share on other sites More sharing options...
Hecubus Posted January 29, 2015 Author Share Posted January 29, 2015 The reservoir tank was at full. Link to comment Share on other sites More sharing options...
MrTris Posted January 29, 2015 Share Posted January 29, 2015 The reservoir tank was at full. OK, well, keep an eye on that level. If the reservoir is overflowing and causing the overheating, you may either have a bubble in your system, or, you have a blown HG again. When you first start it in the morning, is the reservoir level lower or still at full? Link to comment Share on other sites More sharing options...
YeuEmMaiMai Posted January 30, 2015 Share Posted January 30, 2015 are your fans working? Link to comment Share on other sites More sharing options...
Hecubus Posted February 1, 2015 Author Share Posted February 1, 2015 Yeah the fans are working. I gave in and pulled the heads. Drivers side head gasket looks like it failed between the cylinder and coolant jacket. So it was pushing exhaust into the coolant system. I got the heads milled. They took about 6 thousandths off. I'm going to finish putting the intake back on tomorrow. Thanks for the advice everyone. Link to comment Share on other sites More sharing options...
MrTris Posted February 1, 2015 Share Posted February 1, 2015 That's a common type of leak for these motors. Get the ARP head studs 260-4701. They're $185 on Amazon, best cheap insurance you can buy against hg failure in the future. Link to comment Share on other sites More sharing options...
