GM 3100-3400 Thermal Bypass Pipe Replacement




What do you think about this video?

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

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.

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?

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

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 ?

Andrew Smith: Never mind, I found them. :) I guess I should've looked before asking.

mtlh05: Glad to see you back richpin!

Jon Barker: Hey Rich. You have any idea if the quick connectors on the cooler lines come off ? I was able to pop that little clip off but the thing is just being overly stubborn. I'm able to twist, push and pull but it seems to be locked on there. I'm getting the feeling they are not supposed to come off.

babybo601: @richpin ok thanks

Jon Barker: Good morning Rich. I'm doing a full blown coolant flush with cascade to try to get the rust out. I replaced both thermal pipes, water pump and I'll put in the new thermostat after the flush. My question is, which is the heater inlet hose ? is it the one that connects to the long thermal pipe in this video or the smaller one ? Thanks.

Jon Barker: There is a tool they make to disconnect them. I have one on order. It's always nice to have a new tool added to the garage.

Nick C: thanks for the vid, my car has some differences, i dont have the air pump system on my 2005 3.4 impala. but this definately helps. i'm replaceing a valve cover gasket, and need to remove this pipe.. i was assumeing the o-ring in the fel-pro kit was for the tube, but NOW I KNOW.. thanks alot!!

richpin06a: I could not find one aftermarket myself so i had to go to the dealer.

Azat ALBAY: I don't know how it called but my car is 2001 Chevy Venture LS.

Zachary Flores: If you dont mind me asking how much did you pay for it?

richpin06a: I have never removed one of those so i am in the same boat as you.

richpin06a: @Smittyzrx For anyone else that would like a pair like these go to Autozone.com and search for 25198

hp11208: nice tool rich,cool vid

Tyler Slone: I need the pipe that connects to the thermal bypass pipe that runs in the intake manifold what's that called?

P_MONEY PRODUCTIONS: I broke the o ring on mine taking it out lol so i sonofabitched from a headlight bulb. I forgot they were sealed with a rubber o ring into the lenses

Jon Barker: Well i figured out I need a special little tool. Would the A/C quick disconnect tool work the same ? Thanks !!!!

Jon Barker: Yes it is the shorter one. Thanks for the reply. Well everything went pretty darn good except for the fact the kid who I bought it from had that copper stop leak in there and then my power flush re sprung the old leak, lol. Good news is that the cascade and baking soda did an awesome job on all the other metal parts. So I'm just going to order a new one. The trans cooler was nastied up anyway. Thanks Rich.

foxdmulder: @Smittyzrx their very handy and time saving, there is also one with long cable with the clamp at the enf for recessed clamps, handy for bottom radiatior hoses

dany mckoy: hello ,body i have a pontiac montana 2000 motor 3,4,ok the heater hose broken ,your video was great help for me i live in maryland,thanks

babybo601: @richpin I have a 05 impala 3.4 and you just help me alot with my problem my the o-ring on the bypass heater pipe on top of the water is leaking could I use gasket seal or what

Recoil816: Yup - irritates the Hell out of me. *WHEN* it runs good, it's a damn nice car, looks and performance. But sadly, that's not often. If it's not one thing, it's another. Although, I guess that can be said for almost every car.

James Brown: Thanks for the video. Very informative.

eric623nathan: THANK YOU FOR YOUR HELP. I WAS A LITTLE FUSTRATED...

ezell007: I NEED TO FIND OUT HOW TO FIX THE CONNECTOR WHERE THE CLIPS CONNECT THE THREE PIECE PIPE ON MY 94' CUTLASS CIERA 3.1, AND HOW TO REMOVE THAT PIPE THAT'S CONNECTED TO THE CYLINDER HEAD TOWARD THE FIREWALL WHERE THE HEATER HOSE GOES TO THE VEHICLE. THE EXHAUST CROSSOVER PIPE IS IN THE WAY HOW DO YOU GET TO THAT SCREW TO REMOVE IT, ANY SUGGESTIONS DO TELL!!!!

richpin06a: Sorry to hear that.

richpin06a: Check your water pump it is right in that area.

richpin06a: Are you working on a Saturn or a Impala.

richpin06a: Off the top of my head that i would not know.

richpin06a: Wow that was like a year ago i like to say somewhere in the 50.- 60. range

Marvin Lewis: I freakin hate GM

eric623nathan: Im new to this so ill be quick, I have a 2000 chevy impala thats leaking from that exact pipe. my question is where to get a replacement pipe, ive called every auto part store i can think of and no luck. I was told it could be a dealership part but my car was bought used, im starting to smell coolent now, if you can help me i would really appreciate it. excelent video by the way was really helpful.....

Zachary Flores: Well thank you and i subscribed to your channel

Azat ALBAY: Hi, I couldn't disconect the other end which is connected with quick connect clip. So my question is do I need some special tool or just press and pull out? Thanks,

Justin Sprinkle: Hey Rich, any way you can tell me what size of o ring i would need where the thermal bypass pipe hits the left side of the engine over by the water pump?

richpin06a: Had to go to the dealer for that one.

Jon Barker: Impala

richpin06a: It is easy to tell which one is the inlet by starting a cold engine and the hose at the core which heats up first is the inlet.

Gabriel Smith: I failed to mention that I also got a new head gasket.

richpin06a: @eric623nathan Yes it is a dealer part,they should have no problem getting it for you.

whyoohwhy86: Im getting a coolant leak from passenger side only if i let the 3.4 impala idle and it starts to overheat bubble and crackle but if i drive it the temp goes down and car doesn't overheat or leak can any help me?

Kel Vain: Hi, is there a retail store from which i can pick up the replacement pipe? or another name for it?

studpuppy69: @OneMoeAtheist No one cares you're first. Only in Elementary school.

richpin06a: I do not think that would work.It would be best if you remove the old o-ring and find a replacement.

sosjp: Thanks buddy. I replaced the 2 throttle body hoses, and loosened the pipe for access and created a leak. Off to get a new o ring, on Sunday?????? Darn.
