I have an '05 Sequoia V8 that doesn't want to warm up to Operating Temperature. When I start it, it doesn't matter if you let it idle for 5 minutes or 20 minutes it doesn't reach operating temperature without jumping in and driving it around.

Being lazy, I hate scraping the windshield so I start it to "thaw out a little" but when it's cold out (Mid 20's), the temp will come up to just above "C" and will just sit there.

I've wondered about putting a grill cover on it to hold the heat in more. Is this normal for the Seqouia's or could it be a thermostat issue. Thanks.

Thermostat might be stuck open.

 

If the thermostat was stuck open would I see any other symptom's? Once you start driving and warm it up it will stay warmed up. So I assume this isn't normal for the V8 in the Sequoia? Thanks.
