I'm kinda miffed at FlowKooler right now. I sent them a 4 bolt pump last year for rebuild and their new super duper cnc'd impeller. It seemed to work fine but I think it increased the pressure and killed my heater core. No problem. I replaced the heater core and installed a restricter on the inlet side. Also replaced my timing cover due to other issues, so I moved the new FlowKooler water pump over to the new timing chain cover. Got all my work done and went to put coolant in and the flangin' water pump is toast. Coolant all over the place. I'm not sure who to be mad at, but dangit, I ain't happy. That thing cost some moolah. Got a regular old fangled water pump on the way. Should be fine once I swap it out. I think I'm going to give FlowKooler a call and have a word with them.
