I bought fluidyne radiator n dropped it in dc4 bay last month ago. I was shocked that temp needle stay close to C. Im very happy with the result. Today, i started to think its not very good cause its getting cold outside. My question is thats okay if temp needle stay close to C no matter how cold it is outside?





if you dont understand my english, please ask me to rephrase.. ill be happy to explain very clearly next time. thanks!

 

Check your thermostat, as many integras have this issue. The thermostat sticks open, and the engine runs too cool, especially in the winter when you want HEAT. Good luck!

 

It is not prefered for your engine to stay cold. These engines are built to run at a certain temp range.

You can look into getting a new thermo, but depending on the size of the new rad it may not make a difference

 

was the temp needle that close to 'C' before the radiator swap?

I used a fluidyne rad before in conjunction with a low-temp thermostat and fan switch and it dropped temps between 15-20 degrees F (IIRC).

after the engine has been running for a bit feel the top radiator hose. it should be warm. if it is not then your thermostat is most likely the cause and it stuck open.
