can anyone please tell me where they run their coolant piping . has anyone run them through the tunnel?
post some pics as well please
i wanna go through the tunnel, but wanna make sure im on the right track
I got my heater coolant lines up the tunnel, along with the extra fuel lines, new hydraulic brake and clutch lines, plus all the standard vw stuff inside there. Its pretty crowded, there's no way I would have got the main coolant pipes in there. Also you would have to pay attention to the big holes you cut in the chassis front and back where the pipes come out. Also securing them in there, you also want them insulated so your tunnel doesnt get hot, and the metal pipes shouldnt touch any metal of the car and be electrically isolated if possible, otherwise you could get electrolysis issues esp if you use stainless pipes.

Hope this helps, Kevin
I even took a load of rubbish to the tip on the weekend in it & I have never hit the coolant lines.
OK Jak you have convinced me...i have an EJ22 in my kombi but now i really think i need a wrx donk to go to the dump!
Don't put coolant lines inside the tunnel,for the simple fact that if you get a leak it would be a bitch to fix.
Remember the Radiator water is about 90deg, your car would be nice and warm inside. Just try and hold a normal cars hot radiator hose with your hand
to get a idea of the heat.
inside of the tunnel would make a nice bake oven

You can get them enough out of the way under the car -better temps too, wind passing by them, hot not next to cold.
Hi
On my old wasser bug I ran 1.5 inch lines under the chassis following the heater channel bolts.

I used iron exhaust pipes, and bend/welded them in to shape.
They are routed under the main tunnel:

Greetings,

i've gone for 1-1/4 stainless through the tunnel
thanks for the help everyone, will run them under the car now
Y'know, finned tubing in the heater channel might be just the ticket! Add a air blower under the back seat and you've got an instant heater!
