  • Hot Rods Water Pump Repair Kit

    Hot Rods Water Pump Repair Kit

    Dan in WY

    Second kit had more instructions and assembly tool

    First kit had very little instructions, installed it and it started leaking within 2 hours. Second kit had full set of instructions and a plastic spacer for setting the mechanical seal, this one lasted 14 hours. All other seals and bearing in kit work and fit perfectly, will try an OEM mechanical seal next.

    This product is fantastic. I first used it in my 2002 yz426f. It kept her cool and Ive used it ever since. It wont kill your dog if he gets in it and it can mix with anything. Great stuff.

  • Mylers Silicone Radiator Hose Kit

    Mylers Silicone Radiator Hose Kit

    Dan in OR

    Don't know if they are worth it

    Got these to replace a blown upper hose and thought that the upgrade would be worth it. These SUCK to get on. I ended up only replacing the one that needed to be replaced. I wrestled with just one other hose for over an hour and just gave up and ended up putting on the original hose back on. I didn't even try doing the other side because they SUCK to put on. The inner diameter of the hoses is just too small to fit over the openings of the upper radiator inlet and the lower radiator outlet. Getting them over the thermostat housing is a little easier because there is a taper on the orifices. Also the outer diameter is way thicker than OEM so if you have a Trail Tech fan there will be some rubbing. Someone told me that putting them in hot water will loosen them up, but I have not tried that yet. I was also thinking of calling Mylers to see if they have any advice.
