Hey guys so I have a rebuilt 05 civic coupe that was rebuilt around 280,000 now at around 341,000. Anyways everything was fine untill the other day a radiator hose, I guess it just old and a hole appeared and sprayed coolant everywhere. Anyways I replaced the hoze and put in more coolant and the engine begin to overheat from what I am assuming was from air when I added more coolant and or part of the reason was the bad radiator cap. Anyways I ended up replacing the cap everything seemed fine and an engine light I had previously actually went away.

To my horror lol at a friend's house as he was looking over it for me, he noticed that oil was in the radiator on the surface of the fluid. We both pretty much think it has to do with the head gasket and could have been damaged when the vehicle overheated. I actually didn't let the vehicle over hear it got high a little bit but twice but I was able to bring the heat down. I was forced to drive it home and even tho the a/c is off and the heat is on its maximum it still seems to blow alot of heat. Since I am broke at the moment and my car is basically the only way I can get to work due to distance and public transit I wanted to know some others opinions on the situation and what I could do.

 

the temperature gauge isnt instant in most cases so even if it only got 3/4 up the gauge it could have actually overheated anyway. check to make sure the fan is still working. fan should come on with the a/c for an easy test. when the engine warms up check both coolant hoses to see if they are warming up. adding coolant without having the engine running or too quickly can trap air in the system. also the water pump could have a problem. only way to clear trapped air is to drain the system and refill slowly with the engine running.

 

Thx for the reply. The fan and radiator are both good as well as coolent hoses. As for air in the system I will be draining it and doing a refill somtime this weekend. Do you have any advice on draining the coolent as that is somthing I have not done myself

 

quickly is to just yank off the lower hose also messy AF. clean and slow there should be a drain valve located on the bottom of the radiator. draining the system doesn't matter much just drain it and leave it alone for 15 min. debate on adding part of a jug prior to starting it or starting it then adding. ive always put some in then started the vehicle then slowly started adding.
