    Yeah yeah...:D
    it was a special order, on the way. Local autostores didnt have any in stock.

    So that popping noise is the fluid filling radiator paths/air escaping?

    Be prepared to "burp" the sytem, and top it off, in the first few miles. Sometimes it helps to remove a heater hose, if any.

    You still need a wider belt. :whistle::whistle:

    Problem solved, other than the odd pinging noise once in awhile upon startup.

    I'm glad it went well, I'm not sure about the "popping" noises you mentioned though unless it's just burping as mentioned needs to be done sometimes. I seriously can't believe no one mentioned the belt not being wide enough. :D

    Maybe those popping noises are coming from that skinny belt getting stuck in the bottom of those wide belt pulleys? :p

    I would liken the poping noises to an old radiant heat system. As it heats up and pops through the lines

    New stuff. =:poo:.


    Belt tension not too tight, was it?

    Also, occasionally a water pump seal may leak a little, then heal itself, during the break-in period.

    I dont know if the tension is too tight.
    break in period? thats a thing? thought these work, or dont? could it be something else causing the fluid to go out the weep hole?

    I've never had a water pump go bad that quick, that sucks. Where did you get it from? You should have a little bit of deflection in the belt, at least 1/4" between the pump pulley and the alternator.

    Did you change to a lower pressure radiator cap? 1.1 bar > 2 X 7 psi.

    Why would the cap be an issue? that only pops when the motor gets too hot, right? this water pump leaks via the weephole on short drives. like, 100 yards.

    The cooling system is designed for a certain amount of pressure. I personally don't know what pressure it would take to affect the water pump seal, or whether extra pressure could be ruled out as the cause. The pressure relief opens when the pressure gets too high which would generally be caused by heat. What cap do you have?

    What happened when the pump started leaking? Was the engine warmed up?

    It leaks overnight as well. i came home from a short drive, 4 miles, parked, it was fine, then the next morning there was a puddle of coolant under it. the temp gauge works, and it doesnt go to the hot side.

    No, it pops when the pressure builds beyond a safe operating range. I'm guessing the water pump seal is not capable of containing more than twice the design pressure. It doesn't have to overheat to build system pressure that could blow by the water pump seal. I've seen new radiator caps put on weak cooling systems and blow hoses, heater cores and welch plugs.

    Pressure controls the boiling point but if the cooling system overheats it continues to build pressure unless or until its relieved.

    I always suspect any "new" replacement parts. What we see with much manufactured product today is the response to consumer expectations of incredibly low pricing.

    Companies find it more profitable to provide a warranty than to do any quality control. As a friend of mine was told, "We don't do QC. We'll keep sending you replacements until you stop calling."

    Fan belt tension should be ½" deflection, per FSM. You do use an FSM, right?
