d15b7 overheating

By 92civicEGsedan
- Fri May 11, 2012 1:57 am #304570 my d15 uses water alot i filled it up with coolant today and didnt even get 15 miles down the road and my car started to over heat so i pulled over and took the radiator cap off and there was nothing in the radiator but my over fill tank was soaked in water, i checked my oil and it looks fine so i dont think it is the head gasket but i put more coolant in it and it ran fine all the way back home and i have no clue where all my water could be going any suggestions?

I bet your HG is leaking, letting air get from your combustion chamber into the coolant passage, displacing the coolant with air which causes it to overheat while the coolant is forced into the overflow tank.

Oil can be fine but coolant can get dirty.

Drain the radiator and look for any traces of oily film on the surface of the coolant as I did in this thread: http://www.civic-eg.com/viewtopic.php?t=2865

cookie dough looking gunk under the radiator cap is also a sure sign of a leaking Headgasket.

- Fri May 11, 2012 12:59 pm #304610 That stuff is a temporary fix at best... all it really does is gunk up the inside of your cooling passages. This would be the perfect time to do a mini-me swap :thumb:

Injectors are no problem. Just use the ones that are OBD1 since your car is OBD1 (92-95).
ECU is behind the passenger kick panel, behind the carpet. There's a sticker on the side of the ecu that has a code. The ecu type will be in the code:

Just be sure that the car that the P28 comes from is the same transmission as your car (auto or manual) :thumb:
