deezel Posted May 11, 2004 Report Share Posted May 11, 2004 When you first run the engine again, after draining the coolant, there may be some air bubbles in there. This can cause erratic temperature readings. Did you purge all the air out of the coolant system after installing the stat? (warm up to operating temp, rev engine to 3Krpm for a few minutes, top off coolant) Link to comment Share on other sites More sharing options...

supraman Posted May 15, 2004 Report Share Posted May 15, 2004 I have drained and refilled my cooling system 3 times and got the air bubbles out....still read about 200 all the time. Hypertech is no help at all either. Link to comment Share on other sites More sharing options...

Hypertech is no help at all either. Is that 200 reading on the dash gauge or from a scan tool? FWIW, my dash gauge floats around between 185 and 200. EFILive says it stays between 178 and 185...

BenKey Posted May 15, 2004 Report Share Posted May 15, 2004 Yeah, dash gauge is off here too. I tried to lift the needles and adjust them. Come to find out, you can't do that on these gauges. You used to be able to on '99-'02. My tranny temps show 15 degrees lower than they are. ECT fluctuates, hard to tell. Link to comment Share on other sites More sharing options...

MustBBrent Posted May 17, 2004 Report Share Posted May 17, 2004 You guys ought to be proud of me. I did the BB mod Saturday morning. Bought a $1.88 bucket to catch the antifreeze. Took 18" of cardboard to create a runway for the antifreeze to run down. Then borrowed a BB from the next door boy. Took less than 5 minutes to open it up and put the BB inside the canal. Then almost 20 minutes to clamp the 2 sides of the retainer and twist it back inside the grooves without loosing the clampings. Was fun, easy. Now the gauge which used to read 210, stays a small notch below the 185 mark. Link to comment Share on other sites More sharing options...

I was cruising at eighty, and it just stuck there the whole four hour trip, and it made no difference if my E-fans where on or off...I am gladto see i am not the only one having the problem..

Likle i said i am taking the mechanical fan back to houston, but i doubt this is the problem, besides aren't the fans saposed to shutoff above 40?

Wizard Posted May 22, 2004 Report Share Posted May 22, 2004 Does anyone know what the part # for the 180* Powerstat is? I have one and it is running at 200*, just want to know if the part is correct or if I need to drain my coolant to eleviate the bubbles. My part # is 1015. Thanks Wizard Link to comment Share on other sites More sharing options...
vette dude Posted May 23, 2004 Author Report Share Posted May 23, 2004 damnit this is really bothering me, i beat the shit out of my brothers truck, and it still wants toi stay at 185... Is it the LS1 fans? I left my fans in corpus, go figure... so will his 5.3 fan and shroud fit or work? Link to comment Share on other sites More sharing options...
chiel Posted May 23, 2004 Report Share Posted May 23, 2004 To make the air go out the system i allways drill a very small hole in the new thermostat . I have seen new thermostat with had some small device with a spring to let the air through. Link to comment Share on other sites More sharing options...
