LumiDriver Posted November 6, 2005 Report Posted November 6, 2005 Hey all, I've just started having a severe temp problem with my car. When I'm driving, everthing is fine..but once I come to a stop for an extended period of time (I.E. Stoplights) My temp climbs like a damned monkey. But once I start driving again, it drops faster than a rock. Any Ideas on what the problem could be? Quote
birdman Posted November 6, 2005 Report Posted November 6, 2005 id replace the thermostat, inspect the raditior and hoses for any major problems and if its none of that go for a water pump. Quote
supreme_style21 Posted November 6, 2005 Report Posted November 6, 2005 That, and make sure your fan is kicking on when it should be. Quote
birdman Posted November 6, 2005 Report Posted November 6, 2005 yea, should have a primary and secondry relay for them Quote
supreme_style21 Posted November 6, 2005 Report Posted November 6, 2005 What exactly is is climbing to? Its normal for it to rise a bit at a stop.... there isn't any air moving through the front end of the car at a dead stop, so the temperatures will naturally rise somewhat. Quote
birdman Posted November 6, 2005 Report Posted November 6, 2005 keep in mind the thermostat opens at 195 and fan comes on at 212 Quote
Kevinsluminaeuro Posted November 6, 2005 Report Posted November 6, 2005 not te be off topic but what is the normal operating temperature when at idle and when moving? Quote
LumiDriver Posted November 6, 2005 Author Report Posted November 6, 2005 Well, would the engine ALWAYS be hot if the pump went out? Also..it climbs to about 240ish..and the fans don't kick on..and i know the thermo pops, just not when it should..ill check the thermo, and anyone have an Idea of where the relays are? Quote

I wouldn't go with relays. Check the coolant temperature sensor... its right in the front on teh block. If you pull the plug and jump the harness with a paperclip when the engine is above the 220 or whatever temp the fan SHOULD kick on, and the fan kicks on, chances are, that sensor is shot. Its like 15 bucks. Quote
birdman Posted November 6, 2005 Report Posted November 6, 2005 what motor does that have 3100 or 3800? i know mine has two temp sensors, one for the gauge and one for the ecm (ie. fan) mine for the fan was under the throttle body and the one for the gauge was on the back of the block. norma op temp will go up and down between 195-160 moving, still it depends on how long your sitting there but the fans should kick on at 230 and go off around 190. 230 is about 3/4 on the gauge. i would replace the thermo if you know its not doing exactly what it should, there only like 8 bucks.

digitaloutsider Posted November 6, 2005 Report Posted November 6, 2005 Oh man.. a thermostat job on the 60/6 3x00.. I'd rather be shot before I have to do that again. Quote
1990lumina Posted November 6, 2005 Report Posted November 6, 2005 Oh man.. a thermostat job on the 60/6 3x00.. I'd rather be shot before I have to do that again. Is it THAT hard/pain in the ass to do??? There must be a considerable difference between my 3.1 and a 3100...chanigng my thermostat was easy as hell! Quote
birdman Posted November 6, 2005 Report Posted November 6, 2005 mine took 30 min to do thermostat and temp sensor, whats so hard?? Quote
digitaloutsider Posted November 6, 2005 Report Posted November 6, 2005 You also have an LQ1. I'm talking about the Gen-III 3100/3400. Quote
THe_DeTAiL3R Posted November 6, 2005 Report Posted November 6, 2005 Oh man.. a thermostat job on the 60/6 3x00.. I'd rather be shot before I have to do that again. Take the throttlebody off. 3 or 4 bolts and then you got access to it. It would be a major PITA if you leave the TB on. Quote
digitaloutsider Posted November 6, 2005 Report Posted November 6, 2005 Even with the TB off, it was a GIGANTIC pain in the ass on the Montana. Quote
ShockTherapy Posted November 7, 2005 Report Posted November 7, 2005 oh boy, me and ray get to do this bitch some time next week. Quote
