Catastrophic water pump failure
 
Water pump in my 4.7l 09 failed today. The belt started squealing then spraying coolant everywhere. Pulley is way loose.

Anyone else change one? Any tips?

Any chance your still under warrantee?

sethmark 02-01-2013 08:53 PM

Hell no. I'll fix it.

There's nothing to it. If you have basic hand tools, you can do it in an hour or so. The hardest part is getting all the air out of the cooling system.

Any trick? I assume that leaving the cap off and turning the heater on is the right way without the suction tool?

You should have a bleeder screw in the aluminum housing right where the upper radiator hose goes into the engine. Take it out with an allen head socket or allen wrench, i can't think of the size off the top of my head. Fill the cooling system through that hole with the radiator cap off (you'll need a small funnel) When coolant starts to overflow from that bleeder hose put the screw in and finish filling it from the radiator, shouldn't take much more.

I fill it through that small hose because it gets directly into the block much easier than if you just go through the radiator, all the air will get pushed out through the radiator. Thats how I fill every 3.7 and 4.7, I never have to bleed the system after and have never had any problems doing it like that. Oh, and have fun:smileup:

Heres a picture of where the bleeder screw is, in case you've never noticed it before:

Thanks for the help guys. It seems to be bled fine filling slowly from the radiator neck. I ran it the the cap off for about 15 min til the thermostat opened and the electric fan turned on. Ran the heater for a while too and it's stable at 197*.

Sounds like you got it handled. Not hard to do at all, is it?

sethmark 02-02-2013 07:42 PM

I've done a lot of water pumps. This one. Was EASY. WAY EASY.
