Replacing heater coolant pipes?

[Jhonno]

Got my new pipes from ACT.. However, can't seem to work out how to get at the heater box ends of the pipes.. Pulled the passenger's carpet but don't want to start pulling things apart unnecessarily..

[Jhonno]

It's this one btw..

Mine are attached to rubber hoses under the header tank.

[Jhonno]

These go into the inner wings somewhere also..

[ridds]

Are you trying to get the rubber hoses out then?

Try the hatch at the rear of the front passenger wheel arch. If not, they you're inside the passenger footwear on the left hand side to access the heater matrix from there.

Trying to get the hoses I guess attach to the end of these.. Pipes. 2 go througbt the passengers inner wing.. I have pulled the carpet and how have the ecu on display. I am guessing I need to pull carpet etc out as well now?

No one...? Got a day off after holiday to crack on with the Cerb today..

The stainless pipes are shown in grey, the heater stainless in red, There should be two rubber hoses coming through the passenger side inner wing, the stainless pipe without the branch goes onto the lower of these, and the short branch on the other stainless pipe connects to the upper of them. The bottom end of the branched pipe connects to the thin hose that goes across the engine bay to the drivers side main pipe and the lower end of the unbranched heater pipe connects to the short spur on the other main pipe. Top end of the branched heater pipe goes to the expansion tank.

Should all be fairly obvious when you look at it unless you took the pipes off a while ago!

I cannot see the rubber pipes in the inner wing.. The pipes/holes are silicon'd up.. So if I just clear the silicon out I should be able to access them?

[Tanguero]

If you clear the silicone and pull the old heater pipes out a bit the rubber hoses will pull through enough to give you slack to connect. There may well be the remains of large rubber grommets buried in the silicone, they are worth saving if you can as I had trouble finding the correct size grommets when I did my rebuild.

[Jhonno]

Excellent.. You are a legend! Cheers..

They are accessible from the passenger foot well, you just have to pull back a lot of sound deadening:



I couldn’t get the rubber pipes in the foot well to budge from the old steel pipes so had to cut them off, reminds me that’s something else I need to get...

[Jhonno]

Definitely a footwell job.. Not got round to it today, got other jobs done instead.

Worth noting that the heater pipe arrangement changed around '97-'98.

Out of interest, did you find a correct grommet? Both of mine were shall we say, a bit buggered (before I started digging)!
