water pump....wierd...wtf???

[dman1982]

so i went to the veterans affairs office this mooring, when i got there i looked under my truck and it was leaking coolant, so i pop the hood of course, and it was leaking coolant from the bearing in the water pump, so i took a chance and drove it home and it wasn't leaking...is this a common issue?

[littlevictories]

yeah that's where they die. when the truck goes from a hot,run to a hot, off the pressure in the tank builds (no airflow through the rad) and then it leaks. bummer in the summer.

[dman1982]

so i need a new water pump? it does need a new thermostat, its stuck open so it hasn't been running hot, i should have plenty of air coming through the rad, it did it after highway driving

[littlevictories]

yes, the shaft seal has failed. a new pump is in order.
new thermostat yup, they're cheap.
you running a purge tank? highly recommend one on any vehicle. proper psi cap is another key.

Tell me about who has the best pumps cheap!

[littlevictories]

15 psi is stock, and what I used. They do go bad, but usually they pop at a lower pressure rather than a higher one. Cheap enough to just do it.

[dman1982]

gotcha...gonna go out here soon and try and get a water pump...anything special about changing one of these water pumps?

[littlevictories]

nah, not really. the gaskets are like the other gaskets on the motor steel core with a neoprene sealing edge. $5 each and you will need two.

[dman1982]

gotcha....didnt know if you had to shim it or something weird like that

[truckdude239]

nope watch out the last couple of pumps i have bought at work came with the cardbopard gaskets, by the metal with rubber inserts, make sure to buy the same pump and stat brand as there are different size t-stats, i did install one with the card board gaskets and rtv been 12k miles so far no issuse but i like the factory gaskets

This intrigues me. It would be super weird for companies to put a proprietary stat in a stock replacement water pump, unless they were trying to "Fix" something seen as a weak point from O.E.

That would also mean that 3rd party stats (like the 160*s) wouldn't fit any pump other than the original one.

Did you have this problem? I'm curious what didn't fit, and by how much.

[truckdude239]

i bought an ac delo pump fro aut supply here and the had 2 different size thermostat housings

[dman1982]

so i started my truck and drove it around a bit, now its now leaking....wtf???? so freaking weird!!!! it makes sense about the rad tho I'm pretty sure that its not holding pressure so that would explain the low pressure leak...but still makes me mad tho

[dman1982]

so, my water pump isn't leaking anymore, should i still get a new water pump, radiator, and thermostat? getting ready to fix this, can i re-use the metal gasket on the water pump instead of the cheap ones you get from the new water pump?

[dman1982]

or should i try my luck with just a new thermostat?

[truckdude239]

If it was leaking replace it. Do not reuse the gaskets

[dman1982]

well i replaced it almost a week ago...kinda slacking on the updates...new water pump, rad, and bought the better gaskets for the water pump, had a buddy at orileys buy them for me saved me about 50 bucks, came out to 212 so not too bad

[dman1982]

oh and with the rad instead of the 1 inch went with the 2 1/4 inch one...and i put my electric fans on
