Default Something Some Might Find Ineresting
I got out the SRT 6 Saturday for the first time this year ( MAN THAT FELT GOOD). I installed the cooling fans & temp. gauge on the aftercooler/HE this past winter, but didn't get to get the car out. Well Saturday just crusing around town the temp's were between 83 & 87 degree's. But after I started getting into it a little the temps was reading from high 90's to 110 degree's. Dumb a$$ me left the remote for the fans at home, so I didn't get to see what kind of difference the fans would have made, but I thought those were some pretty low temp's (68 degree's outside). After getting home the car was at max operating temp & the radiator fan was running so I got out the remote to turn the fans on, the HE temp's at the time had climed to 133, 5 minutes after turning the fans on it dropped down to 124 degree's. The way the cooling was acting I still think the I/C pump runs any time the key is on, but I also think the pump is a variable speed pump. I think the I/C control module sends a lower voltage(pulse voltage) to the pump just idiling or low RPM's to make it run slower. Then when getting on it or at higher RPM's it gets the full 12 volt's to run faster, I believe that's where the term pulse voltage comes in from the I/C pump control module. Just figured I'd share .
