I noticed a coolant leak at the water pump. I checked around the pulley and it's dry. Where is the weep hole? I'm pretty sure it is coming from the heater hose pipe that goes into the water pump. I noticed the o ring is on the pipe but it isn't in the hole, Its on top of the water pump, I'm assuming it fits in the hole?

 

The oring indeed should be inside the pump. Remove pipe and install new oring with some oil.

 

And check the condition of the pipe. I've heard that they are prone to rust.

 

The pipe has a grove where the o ring sits, There is a bracket that supports it from moving so it may not be in all the way.

 

It's a cheap buy from summit of its in bad shape. I just bought a new one for my plenum repair

 

Local parts stores should have them as well, in the "Help" section. Runs about 15 bucks I think. (seems a lot for what it is.....)

 

coolant tube here
But the downfall is you pay shipping. I ordered a couple things so it was worth it for me to order the tube from them
