Re: Aerostar coolant loss
The 3 litre is know to leak coolant between the block and timing chain cover. To solve the problem remove the rad, water pump and everything else in the way, remove the timing chain cover,(there are a couple of oil pan bolts to remove as well, be very careful of pan gasket, don't break it) put some tape to cover oil pan opening to keep dirt out, clean the front of the block, clean both sides of the timing cover and the water pump. Reassemble with new gaskets, use RTV liberally on all gasket surfaces. It is time consuming but work carefully. I never had a leak after doing this. Have fun.
