Just got a new used 2004 Tahoe and it seems like it takes too long to reach 200F driving around town when it's 68 outside for 10 minutes and it still sitting at around 140F.
I'm thinking a bad thermostat, anyone have an idea?
How long should it take to reach 200?
Do I get an after market one?
Me again,
I replaced the thermostat with an OEM and still in a 68 degree weather it takes 15 minutes to get to 200 F.
What else is there?
I wouldn't be to worried.....as long as it's staying at 200 and not fluctuating up and down.
Running a cold engine for a long time is not a good idea.
