Long term lurker , first time poster. Howdy everybody, I have an old Toyota Camry with a 2.2 4cylinder engine , the entire car has been nothing short of phenomenal , going into another upper Midwest winter I've noticed it takes a really long time for the coolant temp needle to sit where it has for 10 years. If I drive around town stop and go it takes even longer, it seems most noticeable under 45 degrees F apx. This car has always seemed to run really cool even in 100 degree weather to where you can almost ready your hand on the exhaust manifold after summer driving with the a/c on, it has almost 200,000 miles and I've used Valvoline 5/w30 almost the entire 10 years I've had it....I'd assume the check engine light would have come on if there were a problem, am I just being paranoid?!
