Thanks. But the coolant heater sit in the return line of the cabin heater. So all the hot coolant is for the engine to speed up warm up time. And not to heat me. I aim good resistant to cold. Nothing a thick jacket cant handle

Edit 1: I still have to go for the shorter belt to not turn the alternator. But i need to find a way to not have to charge 2 separate batteries. Starting batterie and the deepcycles in the trunk.

Edit 2: The 750W heater is no longer in the car. It is in use to heat the bedroom. Females dont like a chill bedroom to sleep in aperently...
