routing coolant lines

How are you guys routing your coolant lines?

Did you run them down the center between the rear foot pans?

Can you drill into the center of the middle tunnel cover and not hit anything in there?

thanks
Rob

I would stay away from the tunnel there is enough things in there as it is
Rather use your heater tunnels if you want to hide the pipes or other wise underneath in the middle should be fine just remember to bend the pipes up wards at the ends
Good luck

Re: rouying cooant lines

My coolent lines are run on the drivers side, under the running board. I did this because that is the side that the engine coolent outlets are on, its also the side that the radiator outlets are on. (plus I had no time to put the tubes in the heater channels)

Anyways, the lines are not low enough to hit anything even though they are on the bottom of the car. I used copper tubing (doesn't corrode, easy to solder) but you can use PVC (similar to a vanagon), or galvanized steel (thats what kennedy says to use).

All should work well and shouldn't corrode.

Copper will dissapaite the heat better than PVC and easier to solder than EMT.

Re: routing coolant lines

Has anyone tried using PEX tubing for coolant lines? It's a fairly flexible plastic, used in Europe for heating systems for over 30 years, and in North America for over 10 years. It seems to have good high/low temperature resistance and pressure induced bursting resistance. :confusedgreen:

Thanks,
Brian

Re: routing coolant lines

If itís that plastic stuff I think your talking about, Iím not to sure how well it will hold up to road use such as vibrations, bump, etc. Also it could crack? In the home usage, it stays put inside of a wall and not disturbed, but not sure how forgiving it would be if used in the auto industry. Keep in mind also that if used in cars that it would also be exposed to the elements and depending on what part of the country the car was in it could range from below zero, to above 100 degrees. It may also be difficult to fabricate brackets, or hangers etc. It may work ok, for awhile, but Iím sure in the long run it wonít stand the test of time. Stick with the proven metal pipe etc.

Re: routing coolant lines

how can you route the tubes through the heater channels? I mean there are bends in there and it seems like it would be really tough to bend the tube while in the channel or even to solder pieces together in there. What am I missing here?

I would almost concider routing them under the running boards with a skid protector of some sort. Or is this what you guys mean when you say using the heater channels?

good luck

Re: routing coolant lines

i routed mine down the center tunnel. i used electrical conduit like kennedy suggested. and borrowed a conduit pipe bender to make slight bends in the tubes. they come out the stock cover plate in front on top of eachother, and they run along the passenger side of the tunnel on top of eachother, then they curve to the passenger side, and exit side by side, out the little area where the heater cables went and the ebrake cable holder is. on the other side is the throttle cable, other ebrake cable, clutch cable etc.

since you are doing an engine conversion, im assuming you dont need heaterboxes anymore :smash8: so you can take out the heater cable tubes in the tunnel. not as easy as it sounds lol, but after an hour or so it should be done.

after thats out, the tunnel is pretty bare.... you have the accelerator cable, clutch cable, and fuel line and they are all on the drivers side of the tunnel. other than that, the ebrake cable tubes are there, but they run along the roof of the tunnel.

the shifting linkage is in there, but i ran them on top of each other on the side of the tunnel, and they dont interfere with the shift linkage at all. ill try and get pics.

btw i have a type 3

Re: routing coolant lines

I couldn't get you to post some pictures of the coolant lines running thru the tunnel could I? Possibly some shots of where they come out, front and back? Some have said not to mess with that area, but the space is there. Why not use it?
Any pics would be great.
