04 Silverado has a slow leak of antifreeze that leaves small spots on garage floor right under front passenger side of motor. Lots of crawling around to find source I'm hoping someone has had this issue that can diagnose.

 

check the weep hole on the water pump...if thats the sorce youll need to replace it

 

yeah check the water pump. Mine was in the same exact spot and I couldnt find it. I crawled around all over and couldnt trace it until I looked at the water pump. Mine was from the water pump seals being bad. I ended up replacing the water pump. Paid 30 bucks, and took about an hour to install.

 

Sounds like a unanimous choice - I'll start there. Thanks!

 

let me know if you find anything

 

I crawled around and it appears its coming from the seal around so I will be changing this out this weekend and about $130 bucks lighter with the thermostat to boot!
