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!
Justice Webb: Thank you....10/10
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.
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.
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 ?
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
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
dany mckoy: hello ,body i have a pontiac montana 2000 motor 3,4,ok the heater hose

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