2000 Cavalier coolant bypass pipe.

Has anyone here have any experience in installing a coolant bypass pipe in a 2000 Chevy Cavalier 2.2 4 cyl ?

This is the beast that is a metal tube starting from passenger side of engine, does a 90' bend and runs along the front of engine.

had to do it with the sunfire that i had.

dealer mechanic explained it as, support the engine, remove the engine mount, remove and replace the pipe and hook it all back up.

makes a hell of a mess if you don't drain the coolant first.

downside of having to get it done in a relative hurry.

10 minutes max to drain a rad is minor. I'm never in that big of a hurry.

Near as I can tell this is a dealer only part.
Can't see in there very well, is there an "O" ring where the pipe goes into the block ?

That pipe seems to have a pin hole rotted out right in the middle of the 90.
Can't really see where the thing is clamped/bolted to the block tho....

it's a dealer part, there is a rubber oring as part of it that goes into the block(it comes with it attached), can't remember off hand if it's one or two bolts, that secure it.

Good, Thanks...have to go digging and call the dealer.
That thing really looks like "some disassembly required".

I have it happening on a 2000 sunfire. What kind of money are we talking about at a garage?

took me ~2 hours to do, but it took me a while to get the engine mount out of the way.

The guy doesn't list the year in this video, but it looks just like what you describe. The one on this video looks like a simple repair if it's just like yours... Have fun and be carefull with your knuckles!

the large black pipe that goes from left to right just below the plugs and above the exhaust manifold.

no air-box removal required to replace the pipe.

Thanks all for the advice and the video.
I'm not sure the video is spot on but the procedure has to be close.
As for the engine mount maybe its just a matter of twisting the tube this way and that.
I'll call the dealer and order a part.

when you see how far the angle goes in, you will see why it has to be moved.

Update,
Good news is the part was in stock.
The bad news is that the pipe, "O" ring and tax was $137. Ouch.
You may be correct on the motor mount. There looks to be about an inch clearance between the pipe and the mount.

yea that 90degree doesn't look that bad, till you actually have the pipe in your hand and realize how far it actually goes into the block.

not to mention the lack of wiggle room.

Well, that was a pain. You were correct that then engine mount needed to be removed.
The car had AC and one of the metal lines runs right over the mount.
Thanks for the tip.
