Ea82 water pump blown out ?

Featured Replies

So i was re sealing my oil pump and putting everything back together and noticed that i was leaking some coolant off the right side of the water pump, which is lame because i just replaced it in december :banghead:

Anyways pulled it off and saw this: I dont think a water pump should look like this .. It kinda looks like a blown piston lol and sorry for the bad pics, Ipod cameras arent all that great .

Anyone ever had a water pump like this or fail in that short of amount of time ?

Looks like it took some small gouges out of my block too, so there's probably some small pieces of aluminum or whatever the water pumps made out of floating around in my engine :dead:

please tell... what brand water pump was that? GD says the Aisin brand (Jap) is the best.

Its a Master Pro Select, was like 48.99 from Oreill'ys

I took my old water pump out of the box and compared it to the one i made this thread about and they're kinda of similar; they both have like those gouges in around the diameter so maybe thats just how they are ?

 

Anyways i put some high temp rtv around the gasket and threw it back on. Seems to not be leaking ... At least i no longer have the TOD from re sealing the oil pump ! :banana:

Looks like normal casting defects to me. None of that matters.

 

Aisin or NPW are the best. Preference to the Aisin. Paraut is also good but very hard to find any possibly no longer being branded as such since I haven't seen one in years.

What GD said, looks like just left overs from casting. That "piston" is the seal for the pump.

 

I've seen some Paraut water pumps on Ebay. Never heard of them before except on this board.

I've used several Aisin pumps, all have been very well made pumps.

I've seen some Paraut water pumps
rockauto had some for sale a couple years ago. i didn't know anything about them, i bought a ton of them because they were only $8 each. still have one or two.

water pump is not a good thing to cheapout on look at the end where berrings are make shure that aluminum is peaned over the berring the cheaper pumps are not and the berring can creap out i would use a subaru pump have had many many bad ea82 rebiuld pumps and cheapies that failed and do engine damage you get what you pay for
