I was wondering if you can not run coolant through the Idle Speed Control unit like you can with Throttlebody without problems?
Thanks

Coolant Bypass ISC....cause problems?

yeah you can
what i did on my car is put a small metal ball into the coolant hose where it enters the ISC to effectively block off both ISC and TB ( i was too lazy to disconnect hoses
)

I dont understand. Why would you want to bypass the ISC? Wouldnt it make your car idle at ~1000 all the time?
no we are talking about bypassing coolant lines
they are used to warm up ISC and TB in cold climate, however if it never get's below 0 where you live you can bypass them and enjoy cooler intake manifold

probably a bad idea, youre blocking over all coolant flow.
ive had mine bypassed through the winter, no problems.
Thats very interesting, I didn't know that it wouldnt mess up the idle speed. I thought that there was a sensor in it which basically "told" the ISC valve when to open.
I guess now that I think about it, thats what the ECU water temp sensor is for.. which I guess the ECU then tells the ISC when to open/close.. since it is connected by the wiring harness.

Easy fix to this.... there is hose that comes off the steel coolant lines under the intake. Run that hose to the nipple off the front of the head, just under the alt. The nipple up front will be attached to the intake plunnum/runners.
