is there a lower t-stat that fits the fd
 

right now I have an 180f but have heard that there is a 160-170f honda(or other) t-stat that fits the FD. would like a 170F can anyone confirm this? my fd is running around 86-90-94c right now would like to get it a little cooler.

can always count on mahjik. :)

At what temp is the "Low Temperature Thermostat" fully open? If the termostat only opens at a lower temp and doesn't lower the fully open temp, you're car will only take longer to warm up...

If your looking to lower the coolant temps, you should check out Dale's informative thread regarding fan control:

i have the fans grounded to run high speed all the time.

Wow, even if it's 90f out and I'm stuck in stop and go city traffic, my coolant temps are under 200f if I run my fans for any length of time (I've got the old school switch)... Are you running the stock radiator?

He's got a big arse FMIC blocking most of his airflow.

if I put in a 3" fmic rather than the 4" I have, will it help.

Any way you can bring direct fresh air to the radiator will help. Some people duct under the FMIC to bring fresh air:

what about putting a fan behind my big arse intercooler?

Depending on how you drive, wouldn't that pull the hot air off the IC onto your radiator? I guess some airflow is better than none.

I though there was a thread years ago about someone using a TII switch which screwed right in, has the same connector and has a lower turn on temp?

if I put it on the condensor?

also, my rad is still inclined would it matter if I straight mount it?

If you can't get fresh air to it and/or block air from going around it, the orientation isn't going to matter all that much. Ihor spelled it out really well in that link I posted above.

I concur with Mahjik, sounds like you need to do some custom ducting to get fresh air from the front or bottom of the car to the radiator and the hot air coming off the IC out of the engine compartment (vented hood?). You might also consider a different bumper...

I believe you are talking about the FC thermo switch. It would be useless for the OP because he has grounded his fans to run on "high" speed all the time.
