How do you replace a thermostat in a 1995 BMW 525i?

Answer 1

To replace the thermostat in a 1995 BMW 525i, first ensure the engine is cool and disconnect the negative battery terminal. Drain the coolant by removing the lower radiator hose, then locate the thermostat housing, typically near the engine block. Remove the housing bolts, take out the old thermostat, and install the new one with a new gasket. Reassemble the housing, reconnect the hoses, refill the coolant, and start the engine to check for leaks.
