Ok so I had replaced my original water pump after my old one had problems at around 35,000miles back in April of 2009.

Now I just popped the freeze plug out of my water pump that is only 8 months old.. What other problems could be causing this??
I mean 2 water pumps in less than a year?? Thats insane!!

p.s. searched, and searched nothing that deals with my same situation was found..




Any alternatives as water pumps go? anything aftermarket that would help??

 

Blown Head gasket would do it

 

Any mods done to that car? OEM Waterpump should be fine.

head gasket was also replaced in april.. with a multi layer cosmetic

 

but yea thats what I originally tried to argue with my shop which name I will disclose as of now..


I already went through 2 OEM pumps in the last 8 months, so I dont think thats the best idea

 

Are you bouncing off the Rev Limiter when this is happening?

 

^^ helll no haha
I never hit the rev limiter.. I dont exactly drive slow always though.

 

Any mods done to the car? Boost psi?

 

I never understood why the pump his this plug. The passage coming out of housing is not machined. However much pressure the pump can put out at high rpm is going to bare on this plug.

Pull the pump, put some sealant in the bore and replace the freeze plug. Then have someone who welds aluminum apply a few beads of aluminum around the circumference of the the lip of the freeze plug. Now, it can't come out.

 

My car had this problem several times. Auto parts stores carry plugs, I do not recall what the exact size is, but just hammer it in there nice and straight. Put some JBWeld over the top of it and hope it never pops off again. I freaking hate that plug.

 

Sorry this happen bro! Do a compression test bro and go from there. My water pump popped a core plug last week and it was the head gasket. Good luck bro!

 

20ish psi tuned by myself..

Yea I had the same idea, bad design on mitsubishis part..
thats a really smart idea.. bead of aluminum around the plug.
but yea the plug fell off while I was driving, so I'm guessing I could find one somewhere around here

haha yea thanks man, that was my excat first thought from now on all my pumps will get the jb weld treatment

thanks everyone for your quick reply
