Thread: P38 heater O rings

I'd use OEM for the O-rings. You'll know they are the right size.

Thanks, Ron!

Did my o rings last week.

I bought 22mm ID x 2.5mm thick from AutoPro for 50c each.
They worked a charm.

I had two problems.
1. My horizontal duct, the one behind the dash, was screwed to the firewall on the right hand side. I had to drill/break the plastic where it joined the firewall to get it out.
2. When I cut the virtical duct I cut it a little bit too low. This made it difficult to use the hacksaw blade as I didn't have enough room for my hand.

Other than that it was just one of those jobs where you needed the strenght of a lion in hands the size of a gnat.

I'm having a problem or two. I have it all apart - and someone has been there before me - and I have the clamp screw undone and the pipes off. but I just cannot see how I can get at the pipes to get the new O rings on. There seems to be just not enough space! Or am I missing something?

Well - I've got the heater hoses off so the pipes are loose. Just a quick tip for others - take the heater hoses off before you undo the clamp screw! That gives a little bit better access, but I still can't get the pipes out to have a good look at them. at best I'll be able to reach in and get the old O rings out and slide the new ones on. I'd rather get the pipes out for a good look, but there seems to be no way they are going to come out.

Those who said its easy - you're better than me!

You shouldn't need to cut any ducts.

The horizontal duct doesn't need to be touched, just slide the joiner out then rotate the vertical duct out of the . Don't cut it either.

G'day Ron,

According to the instructions given on the RangeRovers.net forum, by Paul.Adshead, you should cut the side duct and duct tape it up afterwards. He reckons you get much better access. Otherwise I cannot work out how to get the pipes out to work on them.

G`day Willem ,

because of the underline/bold above , it may be that the plastic part , where the pipes fit has a crack . ( heater core )

If someone has already replaced the Orings and the leak is still apparent , it would be my worry .

The cracks occur in a circular fashion and unless pointed out are hard to see unless you know what your looking for and it won`t matter how many new Orings are fitted if this is the problem .

p38arover will be able to supply you with a picture if he feels he should ?

Cheers
Peter
