2006 Toyota Camry 2.4L engine. 105,000 miles. Is now a good time to change water pump as a proactive maintenance? When water pump is changed, is draining and refilling the engine coolant a part of job? Some shops list engine coolant as one of the parts in water pump replacement. If draining and refilling coolant is part of water pump replacement, I wouldn’t want to sound like I want to two jobs to a mechanic. One mechanic quoted $300 for water pump change and coolant drain/refill.
When water pump is changed, other than coolant drain/refill, is there anything else I should consider getting replaced in the nearby vicinity? The car has timing chain (not timing belt) which to my understanding doesn’t require replacement. Your advises are appreciated.
