Lex3486 Posted December 1, 2004 Posted December 1, 2004 My car (92 SC300 w/132k, auto) is really sluggish when cold. I know that this is somewhat to be expected, but it seems a little too much on my car. Any ideas how I could possibly improve this?
sc_toy Posted December 2, 2004 Posted December 2, 2004 You really shouldn't be hard on it until it's warm. The trannies hydraulic fluid works better when warm, the heads and block have expanded and are tighter when warm. It's a problem on supercharged and turbocharged cars, if you get to hard into the boost when cold you can blow head gaskets really easily. Just be easy before she's warm. Cheers, Aaron
Mungrin Posted December 2, 2004 Posted December 2, 2004 my car has 115k and takes like 10 minutes to warm up.Anyone elses car take this long?

92Lex Posted December 2, 2004 Posted December 2, 2004 It takes 10 minutes of driving to get it to warm up to normal operating temperature?
Mungrin Posted December 3, 2004 Posted December 3, 2004 no it takes a while for the idle to reach below 1000 rpms thats all. not tempature
92Lex Posted December 3, 2004 Posted December 3, 2004 That's pretty much normal for you car to take 10 minutes to warm up on a cold start. Letting your car idle for 10 minutes isn't good for catalytic converters though.
bartkat Posted December 3, 2004 Posted December 3, 2004 Maybe on a really cold day. But the fast idle should come off sooner than that.
Mungrin Posted December 3, 2004 Posted December 3, 2004 i usually start my car leave and come back like 10 minutes later and the idle is lower where it is suppose to be.When i first start the car the idle is kinda high.THe thing is,it does this even in the summer.
92Lex Posted December 3, 2004 Posted December 3, 2004 10 minutes is for your idle to go from high all the way down to 650 is normal isn't it? I wouldn't suggest letting your car sit there for 10 minutes idling every single time though. Just do what barkat suggested and swap out your thermostat.

92Lex Posted December 3, 2004 Posted December 3, 2004 It's very easy...it should take you about 5-10 minutes. The part will probally set you back 12-15 dollars.

92Lex Posted December 4, 2004 Posted December 4, 2004 Take a pic of your engine and I'll show you how to get to it.
92Lex Posted December 5, 2004 Posted December 5, 2004 Drain about 1/2 gallon of coolant from your radiator. Follow the radiator hose back to the block and there should be a metal housing that the hose is attached to. There's usually 2 screws that hold the thermostat housing in place...remove those 2 screws and you should see the thermostat. I can't really see which hose leads to the thermostat in the picture though. I wouldn't really be able to tell you exactly which parts you need to remove unless you give me more pictures. Maybe someone who has an SC3 can chime in. Take some pics from the driver side of the car.
