Water Pump.... Again? 97 Taurus
Hello all... I replaced my water pump about this time last year. Of course, the impeller was deteriorated to the point that the pump would not work unless at a high RPM. Well, one year later and I am not having the same symptoms as before. The car runs fine, but after a while it will overheat unless I am moving, or if I put the car in neutral or park while at a stop sign/light so the RPMs increase. I replaced the thermostat today but it did not help. Oh, and I have no heat. Also, about 2 months ago at T coupler for the water bypass hose sprung a leak. None of the local dealers had them in stock and said it would take weeks to get one. I ended up putting one together from hoses from NAPA. It worked quite well. Anyway, I flushed the system and got all of the brown coolant out. I even backflushed the system and the heater core. Now, I am dealing with this overheating issue again. When I removed the thermostat, I started the car and water just trickled out of the engine, even though there was plenty of coolant in the reservoir. My guess is the fins on the replacement water pump have already deteriorated and I will have to replace it again. I was just wondering if it was possible for this to happen in such a short period? Any ideas on how to properly diagnose this without removing the water pump. I will do it as a last resort. Thanks.
