That's right, not a typo: 3rd time I'm having a leak at the water pump.
I know I know, you get what you pay for. You buy egay and you're taking a gamble on the quality. Well I took the gamble and I lost.
When I rebuilt the engine I bought a water pump kit for like 70 bux or something on ebay. Car was fine for quite a while. Then I started noticing a drop or two of coolant under the car every morning.
No biggie but it worried me so I diagnosed water pump gaskets as the culprit. Went to vatozone and got new ones. Put em in. It was fine for a while then started leaking again.
This time (about 4-5 months ago) I went straight to Mazda and bought OEM gaskets: the one thats between the wp and block, and the one between wp and waterneck. Install em. Car is great for about 2-3 months.
A couple days ago I finally installed my DIYPNP and started the car up after sitting a while (about a month it sat in the garage waiting on new ecu).
It warms up and now I've got coolant dripping from the front pretty badly. Yank the belts, covers, and here is what I see:
Now its really hard to see in the pic (so I circled the approximate area), but I can clearly see coolant SLOWWWWLY easing out from under the pump and trickling down onto the oil pump, then pan, then dripping to the ground.
Now at this point I'm pretty sure the pump is either defective or deformed somehow since its tightened very well and has OEM metal gaskets in there.
So before I run into the same problem, I want to make sure to pinpoint the EXACT problem and eliminate it permanently:
- Is it just because the pump is ebay and is a POS??? AFAIK
there are tons on here running them with good results.
- Did I overtighten the pump somehow and warped it?
- ?????????? anything else?
I'll be getting a new non-Ebay pump of course and another set of OEM gaskets, but want to get your take on it.
THANX IN ADVANCE
