S300 engine overheating
hey guys I'm getting a little confused . I have a 92 civic turbo fully built and after 20 mins of driving a cel pops up . Code 11 engine overheating. But my temp gauge sits little below the middle. S300 shows 226 degrees Fahrenheit . Coolant was bled properly and fans are working fine.Has anyone had this problem before

Re: S300 engine overheating

Re: S300 engine overheating
not saying it is the problem, but have you tried checking the temp sensor to make sure its functioning properly?

Re: S300 engine overheating
If you are running a half radiator, and the other side is open, try blocking it off and use some weather stripping to seal the block off panel to the radiator, and chassis/radiator support on the other side to force air flow through the radiator. This worked on a friend of mines B16 turbo setup when he was having similar issues.

Re: S300 engine overheating
I'm going to swap the temp sensor. And I have straight antifreeze in their now so I'm gunna drain it and put distilled water with some redline water wetter and see if that helps

Re: S300 engine overheating
There is two different sensors, one for gauge and one for coolant temps. Although I would think they run about the same. Do you have a thermostat in? And ya straight antifreeze is not good I'm sure the bottle said concentrate and told you to mix in with water. Is it a Fresh rebuild? A fresh build will run hotter as it is breaking in, Higher Cr's will run hotter. I tried out Pentofrost 50/50 with distilled water best stuff I have used so far.
Although I have not tried straight distilled and water wetter yet I like to have a buffer for a potential boil over.
I'm sure everything is fine you just have pure antifreeze in there. If antifreeze was good we would not use water, thats why its 50/50
Antifreeze just gives water a buffer between the two buffers, too cold n Too Hott. Which I'm sure you kno.

Re: S300 engine overheating
No I dint use straight antifreeze , it was 50/50 mix. But I drained the coolant and used distilled water with red line water wetter and it dropped about 10 degrees. I still want it to run cooler so I ditched the single core radiator and bought a mishimoto dual core with fan shroud . I'll put it in on Thursday and see what my temps at then.

Re: S300 engine overheating
I used to see that code often in the summer time with a stock engine (while I was rebuilding). the overheat temperature i think is often set too low for safety in the s300, i believe it is in the protection tab. In my case I increased it as data logging showed the temp was in acceptable ranges.
