: The experts say to stick with BMW antifreeze. Local Dealer wants $20/gallon.
: How many miles on your car and what's the condition of your hoses, water pump and thermostat?
: As an easy test, squeeze the hose that leads to the aux pump with and without the engine running. It should be under pressure so you can at least confirm that coolant is going through it, or trying to. On my 535 it tees off from the top hose so is pressurized when the engine is running. Don't know about the V8s.
: Hi Adnan. I have 91K miles on my car and the block was replace around 56K miles with a new water pump. I can't tell what the condition is on
the thermostat, but the car is not overheating under normal driving conditions.
: : Here's a new development.. I pick up my car from the mechanic after getting new thrust arm bushing put in and I heard the coolant aux pump spinning! The engine was turned off, but the ignition was on. I felt heat coming from the vents again, but went away once I started driving. I stopped the car and check the hose going to the pump and didn't feel any pressure. Could there be any blockage? Or could the heater valve be bad?
