Engine Cooling problem
1996 BMW 316 4 cyl Two Wheel Drive Manual 113000 miles
recent mechanical breakdown of water pump so changed thermostat radiator waterpump header tank cap. Its been hot in the uk mid 80s the car hold good temp half way on guage even in traffic. The coolent rises in expansion when hot as expected but when it cools over night the level drops from where it was the day befor about 3mm per day with regular use. Blead system again via manual checked all over for leaks and had pressure test all seem ok so why the level drop from day to day when cold. Please help. Could it be just the extreem hot weather?
