94 olds vert Posted July 6, 2010 Report Share Posted July 6, 2010 My cutlass with the 3.4 might get up to 215-220* on a hot day when sitting in traffic. But usually cools off when I get moving again. Usually stays around 200. I've replaced both my radiator and thermostat. If you think your rad core might be clogged blow it out with compressed air and then rinse with a garden hose. I would not use a pressure washer that might be too harsh on the fins. If your radiator fluid is old you might want to flush it. Quote Link to comment Share on other sites More sharing options...
Galaxie500XL Posted July 6, 2010 Report Share Posted July 6, 2010 Do the fans come on when the A/C is switched on? At least one should any time the A/C is running. If so, that eliminates a bunch of things. Quote Link to comment Share on other sites More sharing options...
WhatTheFehl Posted July 6, 2010 Report Share Posted July 6, 2010 You checked the cooling fan relays, correct? Cooling fan temperature sensor, on my 3100 it is near/behind the throttle body, I would assume on your LQ1 it is in a similar place. Quote Link to comment Share on other sites More sharing options...

WhatTheFehl Posted July 6, 2010 Report Share Posted July 6, 2010 Relays are in the fuse panel in the engine compartment. I think the originals were green... its a plastic block about an inch square... Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted July 6, 2010 Report Share Posted July 6, 2010 those temps are perfectly normal... your stat is 195*, and the fans aren't supposed to kick on until at least ~230 anyways, depending on BCC... Quote Link to comment Share on other sites More sharing options...

occupant Posted August 14, 2010 Report Share Posted August 14, 2010 And what Robert says is true, and the reason being the computer needs the engine running at 195 or above to control fuel and timing properly. The manufacturers assume the car will always have the right cooling system composition (50/50 coolant and distilled water) and the right amount of pressure (anywhere from 14 to 22lbs depending on the vehicle) in order to protect the engine at temps from 195 to 250 or so. When part of the cooling system fails, either by neglect, wear, abuse, electrical problems, or mechanical failure...the engine is no longer protected as well and the computer does NOT care. So keep up on that cooling system! Quote Link to comment Share on other sites More sharing options...
