Signs you need this water pump Coolant weeping from the pump weep hole Overheating or a temperature that climbs A rough or noisy pump bearing You are already doing the timing belt Features & Function Circulates coolant through the engine Correct pump for the E07A Restores reliable cooling Installation Specifications Difficulty: Advanced. Estimated time: about 2 to 4 hours. Required tools: A socket set, a coolant catch pan, and belt-timing tools. Oiwa Garage Tech Note "On this engine the pump lives behind the timing area, so do it with the timing belt - the labor overlaps and a weeping pump can ruin a fresh belt. Bleed the system after." Frequently Asked Questions Should I replace this with the timing belt? Yes. The labor overlaps, so fitting the water pump during a timing belt job saves a repeat teardown. Do I need to bleed the cooling system? Yes. Refill and bleed the air out so the pump moves coolant and the engine does not overheat. How do I test the water pump? Look for coolant weeping from the pump weep hole and, with the belt off, feel the pulley for bearing play or roughness. A weep stain or a rough, noisy bearing means the pump is due.
