My Impala (2001, 3.4, 50K) just had two repairs. BlockHeater was leaking
coolant. The coolant sensor broken (the second time in two years - too many
repairs). Both replaced.
I just got the car back home from the dealer, and took a look at the coolant
tank. The Dexcool level is 4-inches above Hot mark! This seems not right (
too high?). The level used to be at Hot, and almost no change for years. I
called the dealer, and was told: it's fine as long as it's above Hot mark.
Is that right?
