On my way to pick up kids from school I noticed no heat from the vents. I took the long way home to see if it got better when the truck warmed up. I noticed the temp gauge creeping up well above 200* so I pulled over right away.

Looked under the hood and see coolant puking out from somewhere. It slowed by the time I could trace it, but it looks like it could be coming from the coolant weep hole. Would it drop so much coolant if the water pump was bad? Anywhere else on the front of the block it could be from?

It looks like the radiator is about 1/2 full, so I think I'm going to tow it home...

FYI, just put in new coolant and water pump, fan clutch, serpentine about a year ago.

 

Meant to say leaking from water pump weep hole - coming out very fast!

 

Depends on how the seal went, they usually start small, but I have seen a seal let go and pee coolant pretty fast.

When you get home, use a mirror to look at the weep hole.
