    Poor Heat in Both Front & Rear Units

    I don't think we should call it bull, but the average guy would take longer. I watched the video and they did it, but they are fast and seem to know where everything was.. The book says it's an 8 hour job. My coworker used to work at Ford and the fastest he's seen it done was 3 hours. He used...

    Poor Heat in Both Front & Rear Units

    Hi, did you ever get it worked out? Did the wayerpump fix it? Maybe you can try the CLR like shinobi did. I was told my mechanic that over time the heater cores develope a layer of gunk/corosion on the inside of it and the heat transfer is lessened to the cores themselves. I also read...

    Poor Heat in Both Front & Rear Units

    I have also read in this forum that the t's are reduced in diameter. The hoses may be 1/2", but the t's are reduced to only 1/4". Some had cut those t's off and replaced with 1/2" copper t's. This increased their heat output. I'm not saying this will fix your problem, but just a...
