This car came in overheating and running poorly.
We check the codes and there was a code stored for the EGR system. We had to get the car running right before we could test the EGR system.
We found the head gasket was leaking badly causing it to run poor & overheat right away. After we sent the head to the machine shop they also found the valves were not sealing. We had them fix the cylinder head. After we got the head back we tried cleaning the the EGR passage ways and the valve to save him some money, but that didn't fix the EGR code, so we replaced the valve for free.
After we fixed the head gasket and the EGR valve the car ran great and never over heated.
The customer came back 20 days later and said it was still over heating. We tested the cooling system and all the fans were working properly and coolant was full and clean. We check the temptarture on the radiator and found it was plugged up, not cooling the coolant down enough, and would need replacement for best fix. Flushing it out was just a temporary fix & will need replaced for a permanent fix. We did flush the coolant system after the we installed the new head gasket. and drove the car about 20 miles and car never overheated for us. The customer drove the car for 20 days before it started overheating again on him. I still believe the radiator is going to need replacing.
Thanks, Terry and Tracy
