So, have never heard of such a thing--a hot water pump?
A/C not working. Gave up on the DIY ethic, and went to an indy. Plugged a beaten and battered Baum breakout box and reader into the interface under the hood. Told me my hot water pump was not working. Then, evacuated the A/C system, charged it, put in blue dye and oil, and it got slightly cooler, and didn't last for 5 minutes--$102.80. Will bring car to him again tomorrow so that he can search for the blue. Oh well. Seems A/C is something I have to pay for. Gauges, gasses, valves, pumps -- too mind bending for me. Wrenches, jacks, jack stands, sweat, grease, grime, lacerations and swearing, I can deal with. Gasses and gauges confuse me. I guess I need to set aside about $1,500 for this reaming. Such is life.
So, have never heard of such a thing--a hot water pump? It looks to be an electric pump, low in the engine compartment, deep into the engine bay, along the uniframe, on the driver's side, running parallel to the engine. Doesn't look like a big job to replace, but then, it could take every tool in the shop.
What is this; what does it do; why is it my my car; what grease-monkey technique can I use to determine if it's working ?
I wanna be sedated.
