This is what 150,000 miles and 7 years does to your water by-pass pipe.

As part of a repair and upgrade job on my 05 LGT, I replaced the Oil Cooler.

Figured I would share with you all the glorious image of the water by-pass pipe coming out of the oil cooler. I need to replace this.

Also, for good measure a picture of the old oil cooler and the new oil cooler and half my dad's license plate number.

Here's my old pipe at 154,000 miles.

And the new one installed.

I painted it with high temp paint. We'll see if that helped in about 6 years.

Nice. Just found the other thread on here about this pipe, which gave me the PN. I'll be dropping by the dealer to grab one and the two elbows.

Almost 8 years and 92k miles

Mine has a little rust on it for 4 years and 61k miles

Took a look at mine after I read this thread, and was relieved to find mine appears to be brand new (looks like dealership replaced it before they sold the car to me approximately 6 months ago)! Interesting that this part isn't galvanized given where it is...

This part SHOULD be thermoplastic and then it would NEVER have a rust issue. Stupid design.

Assuming the heatshields are as good as we hope they are, agreed.

Damn... I'm glad I don't live in the northeast... that's a lot of rust on the pipe and sheet metal... ouch... there are some pluses to living in southern california

Not enough to way out the negatives IMO.

POR-15 works wonders on parts like that, provided you brush it on onto new clean metal. After many years underneath my last car in the Northeast, I have yet to see a sign of rust or chipping on stuff I painted with it. High-heat enamel? I give it a year max. POR-15 is amazing stuff.

X2 to that one. But I guess if I grew up there, it might be different. I did spend 4 four years in the high desert in the late 70's. But I think its changed a lot since then.

POR-15, I'll have to check that out. Thanks,

Hey, I wonder how that stuff would work on my 86' Ford F150...LOL

I also use por15 on my rusty 91 loyale. Hands down it can't be beat by any other rust and under coating I've used. I'm also painting my water pipe with the stuff while the engine is out.

Make sure you topcoat it with something you like (regular enamel). If you don't it turns flat/ashy if exposed to UV rays. Doesn't affect the way it works, just looks ugly. I don't paint anything anymore unless it has been underpainted with POR-15 first.
