Hey guys, I have a 2001 5.9 and it seems to be leaking coolant from somewhere and I haven't tracked it down. Anybody know where the weep hole is on the water pump? It seems to be wet around the water pump but the pump itself is dry. Any help is appreciated. Thanks.

 

its hidden above the balancer

 

Upper rad hose, thermostat housing, by pass hose, engine coolant temp sensor, timing chain cover. Check them all. And the hole is behind the WP pulley on the bottom of the WP.

 

the weep hole is directly above the big green drip on the bottom.

 

That's another good place to look. DV has it right again.

 

Thanks for your help guys, I'm just gonna have to take it apart. It looks like it's coming from the wp gasket though.

 

It's rare that it would leak from there, and more common for it to leak at the timing cover to block. Clean everything off and check it out real good. Try tightening all the bolts on the front of the motor first also.
