GM 3100-3400 Thermal Bypass Pipe Replacement




What do you think about this video?

Ran Philippo: where i can get this pipe i got chavy Malibu 2000 3.1L SFI it is fit for it? its really look like the same pipe

financeranger: another great vid richpin, I replaced my thermostat (in a venture) and now the o ring is at fault. I was bleeding air out but it kept spurting out of the base. Hoping I can just replace that....esp after I just re-installed this very pipe to replace the thermostat. Bracing for dealer cost...lol

Ted B.: Thanks Rich! This video was super helpful for me to troubleshoot my 2001 Chevy Venture. Is it possible to simply replace the o-ring if that's the source of the leak? Can I just undo that one bolt, pop the elbow up and out with a hammer, replace the o-ring and push it back in? Do I need to worry about air bubbles or flushing the system afterwards? Thanks again!

Chris Keegan: Hey Rich, can you offer any help in replacing the other bypass pipe, the one that runs underneath the plenum? I got one off ebay, Dorman 626-107, which replaces GM #12590279. My vehicle is a 2001 Chevy Venture. I tried banging it in every conceivable way, even cut off portions of a lawn mower 5/8" spark plug socket-wrench as a make shift tool, which was made of too soft steel to be of any use (seems to make the most sense to hammer from above). Do I have to to fabricate yet another tool in the attempt to bang the suck into it's hole? Or should I just shave off whatever I can with emory cloth and fill in the gaps w/silicon or jp weld (whatever it's called)? Thanks in advance.

Justice Webb: Thank you....10/10

dltafrc17: where can you buy the bypass pipe? i cant find it anywhere

beretmp15: I am about to replace all my cooling system pipes and hoses because of severe rust. My question, Why do those hoses from bypass connect to the throttle body? I have it in my hand and have tried to figure it out bu just does not make sense to me. since the pipes on the throttle body are alto rusted away i just cut them off and will just use a flexible hose to connect them two on the thermal bypass hose. do you think there is a purpose for that. TIA

Jim Turner: The one thing you left off was how to properly use that dumb-ass GM cooling system quick connect. Do you put the plastic piece on the end of the pipe and then push the end into the coupler? Or do you leave the plastic clip inside the coupler and push the pipe into the opening?

Demetrius Cole: if you can how much did you pay for the pip?

mobes329: Hey Rich where did you find that hose clamp removal tool ?
