pvc pipe??????

[mccarlk]

trying to reroute my cooling on my mci 5, is it ok to use the pvc pipe that you get from home depot, will it withstand the heat and pressure, thanks for you input, ken, im talking about the 2 inch diameter pipe from the rads to the block

PVC pipe cannot take that temperature.  That is why hot water would use CPVC - but CPVC does not come in large sizes.

(I tried PVC in 190 degree temperatures, and I had leaking.)

I wouldn't trust PVC to take the long term vibration either.

I am pretty sure that CPVC (the plastic pipe that is rated for hot water) has a max temp of 180.  I would never trust any plastic pipe with something as important as engine cooling.  Might save a few bucks on plumbing and have to buy a new engine.  Jack

Why not copper?

[gus]

You may be able to get away with rubber hose for the whole thing.

Why not use stainless automotive exhaust tubing ,bend it any shape you need it. most muffler shops have a pipe bender.  Glen

No good. Stick with Copper. M&C

Hello :
           Copper or brass in my opinion. 
   You might be able to find scrap fittings in the junk yard.  I would replace all hose with new.  CLamps are especially pricy so finding them in the junk yard is a plus..

If you are going to be doing some major replumbing of the engine cooling system you may want to check on the coolant hoses Daniel McMurphy has for sale in the BCM classifieds.  They are brand new hose material and priced well below retail I believe.  Plus it goes to a good cause.

You still probably need copper pipe for a lot of the system, but then you'll need some of this hose material for connections.

i have tried to buy the hoses from the daniel murphy  page, but it says there is a problem with the sellers email, who should i try to contact

I would encourage the fabrication of some metal pipe to go with some short pieces of clamped, straight "hose of your choice" pieces, same as stock.

There will be vendors in your area that fabricate replacement cooling pipes for the big trucks, as they are made of steel and rot out periodically in that duty cycle. Custom pipes is their thing.

Big Transit here, have often fabricated copper pipes as modifications to poor stock designs.

The elbows and pipe stock available at a well stocked plumbing vendor of your choice. Same as plumbing the house, proper prep, more prep, then some prep, and away you go!

happy coaching!

I found the problem.  There was a typo in the email address.

So, if you use copper pipe in a cooling system, is conventional sweat soldering OK or should you use silver solder?

[Melbo]

Conventional household solder will be just fine unless you plan on running steam through your pipes.

Water anti freeze combo "should" never get above 250 degrees at sea level

HTH

YMMV
