Just wondering where should the teamp needle location be when the car is completely warmed up? Mine stays at like 35-39% it is never half way... it never even gets that far..???? I was thining isnt this bad because the oil doesnt get completely warm and that would mean it doesnt lubricate the engine correctly? Or should I just use thinner/lighter oil just in case and its fine?
Nah, your car is fine. While most cars the "middle" is normal, it's not the case with ours. The middle is actually a big hot.
During cold weather, mine stays at 25%.
In hot weather with A/C on, it can get up to 45%.
If it's *really* hot (95+ F) and I have the A/C on full blast, i can get to the middle and some times over (if I'm going uphill or doing a lot of stop & go)
I should note that I recently overhauled my cooling system -- replaced thermostat, radiator, water pump, fresh coolant, and upper/lower radiator hoses, so this would be close to "optimal" performance.
