4K Heater Pipes

[peterd]

my car was missing the heater hoses and copper pipe that runs past the engine when I bought it.

I can't find any part numbers for the rubber hoses. can anyone let me know where I can find the correct hoses?

 

Is there anything special about the copper pipe?

 

it's a 4k in a ke35.

 

(thermostat to copper pipe, copper pipe to firewall. and the return)

 

thanks

Copper vs rubber won't make a lick of difference

[peterd]

at the moment I've got two long flexible hoses connecting everything. I can't get any heat out of my heater although I've got a newish clean radiator, brand new heater core, no blockages asaik, working thermostat and the heater controls/fan seem to be ok.

in another thread altezzaclub said that the copper tubing is a pressure pipe for the heater, so I thought this might get my heater working.

I can't think of anything else.

Did you see my post about checking the control rods for the tap and hot/cold flap?

[altezzaclub]

altezzaclub said that the copper tubing is a pressure pipe for the heater

 

It doesn't affect the performance of the heater, its just takes more pressure than a long rubber hose will.

 

If you disconnect one hose at the motor, does water pour out of the hose via the heater? Have you tried putting a garden hose on one end and seeing if water pours out the other?? The problem with that test is blowing the soldered joints open on the heater, so it wouldn't pay to put too much pressure down the pipe.

 

But if you can get water circulating through the pipes & heater & heater control valve, you've covered half the problem.

 

The other half is as Taz says, the controls for the flaps so air is actually flowing past the heater coils into the car.

 

In six months we'll all be trying to get the aircon working!

 

I'll just edit this in-

 

Altezzaclub wrote "The KE70 has the dizzy side pipe with the copper tube as the pressure feed to the heater. It starts under the thermostat where the water pump is pushing hot water into the top of the radiator."

 

When I got my car, the heater wasn't connected (because it had a leak) and the hoses/copper tube were missing. I connected the heater with tubing but no pipe. So without the copper tube as a pressure feed, do you think this is stopping my heater from working?

 

Its a circuit, so the water flows from the end with more pressure to the end with less pressure. On the KE70, the water pump pushes water into one hose (driver's side) and sucks from the other (passenger's). The KE30 have one hose going to the back of the head, which I think is the low-pressure end.

 

It will work with just rubber hoses.

Thanks for all your help.

I'll have another crack at it soon. Winter in Perth only lasts a week (and that was last week) so its not urgent.

Luckily as long as I can wind my windows down, my air con will always work.
