My water pump went out about an hour ago. As soon as I jumped on it water hit the windshield. It appears a little is coming from the weep hole but 99% is gushing from the bottom where it seals to the timing cover. Anybody ever have this happen? Usuallt when they go bad they just leak from the hole.

off topic but, how were u able to get the timing pointer on without mods?

i bought the same pointer but it didnt line up with my front cover holes. i had to slot the holes in the pointer to get it to fit [:@]

 

I didn't have to modify the pointer. It screwed right on. The timing cover is the universal cover from Summit. I actually cut off the mount for the pointer (for later model years) while I had the pump off. It was rubbing on my hose.

I found the problem with the pump. It blew the gasket right out the bottom. I am definately running too much pressure. A couple of days ago it was the heater core and now the water pump. I need to restrict the flow more. I can't see why the thermostat is not doing that.

How old was the pump? Are you running an underdrive pulley? Are you sure the pump was torqued properly? Why do you think you need to restrict more? How old was your heater core? Cheap aftermarket heater cores don't last long period. You could be creating more pressure by restricting flow also. If the pump was new I would just put another one on it and hope it was just defective.

 

[align=left]TripleH, thanks for the input. The pump is new. I am running uderdrive pulleys. I installed the pump as I received it from Summit. I did not re-torque the two bolts holding the plate on the back side. I have no idea how old the heater core was. I have never had this happen. Should I be able to replace the gasket beneath the plate and bolt it back on? Nothing looks injured.

 

Restricting flow will just increase pressure even more, which appears to be the problem. The gasket and the shaft seal at the weep hole both failed, which indicates excessive pressure. Are you running an overflow tank with the right pressure radiator cap?

 

correct me if im wrong but doesnt the radiatior cap regulate pressure. restrictions just cause a buildup and higher pressure behind it.

here's an article

pressure relief valve. thats my thought

 

If you installed a restrictor, I would remove it. Buy a Good Amercian Made Heater Core. If the pump is covered by warranty I would send it back, if not just put on a new gasket. I have seen some underdrive pullies cause problems. How long has the car been running before the heater core blew? If you have been running for a while, then the Heater Core blew it could have just been an old core.

 

[align=left]No restrictor. The car has less than 50 miles on the new engine. I do get on it more than I should, thus creating higher pressures. I can only hope to just replace the broken stuff with better quality parts. That way it won't break as often.

 

You need a good radiator cap with the correct pressure rating and an overflow tank. The cap does function as a pressure relief/control valve like Kramer mentioned. If the cap is bad, rated too high or stuck, or it's not the type with a relief valve, then you can get excessive cooling system pressure.
