Default Water Pump Leaking

well after spending a nice weekend working on my truck that ended up with me getting a big lump on my head i started loosing coolant like crazy the next two days.

Long story short i found the leak and its leaking from the weep hole on the bottom of the water pump. It leaks all the time even when the truck is not on. I filled it up with coolant this morning before i went to go to the gym and when i came back to drive the truck it was leaking coolant and the truck hasn't even been running for 10 hours.

so i start lookin at the thermostat housing and could find no leaks and even torqued it down one more time for good measure. and started following up the leak from the bottom up and plugged up the weep hole with my finger and it stopped leaking.


so i guess this means i need a new water pump

ha Freakin HA sam


i think the dealer chargers 900 for something like this.

from what i hear the TCM, Starter, Harmonic Balancer, Fan all have to come out.

i might as well just pull my IC, RAD, and ac condenser and clean power wash them and aww hell ill buy an lbz cp3 pump and throw that on there too while i have the tuck down for repairs.
