    Bobcat 743B Getting hot

    Would a quart of CRC do it of should I buy a gallon? By flushing, am I just pouring it through there or Should I close the system and let it sit awhile and then flush with water?

    Bobcat 743B Getting hot

    I thought it was the water pump making noise but when I removed the fan belt cover the noise went away, I think the alternator may have been slightly rattling against it. I pulled the water pump off and it looks decent, the bearing seems fine and the impeller looks good to me but please see...

    Bobcat 743B Getting hot

    When I purchased the machine, the ground that runs to the engine block from the chassis was disconnected and probably had been for quite a while. There are two other grounds from the battery to the chassis. I knew when I saw that ground disconnected It wasn’t a good thing. I’m going to pull the...

    Bobcat 743B Getting hot

    I’m not sure either, I bought it this way. I’ll be sure to us the correct stuff when I re-assemble it. So I would imagine that I probably have a plugged radiator from the looks of the build up. The inside of the radiator looks good at least the small portion I can see. Is there any way that I...

    Bobcat 743B Getting hot

    Well I thought I had the problem fixed by flushing the radiator and clean buildup out of the in-line coolant heater but it started getting hot again today. It was 104 outside yesterday and it stayed 3/4 of the way on the normal portion of the temp gauge. Is there a good type of radiator cleaner...

I noticed a yellow wire with a blue stripe hanging down near...

    Bobcat 743B Getting hot

    I pulled the thermostat out and it doesn’t begin to open until after 200°F And closes around 180°F. I noticed it did not have the rubber O-ring around the edges of it, could that cause a problem? I checked the engine and radiator with an infrared thermometer, The highest reading I got was just...
