Heater plumbing Question

We are removing all of the coolant heaters from the interior and I am trying to determine the best method to blank off the lines.

There appears to be coolant lines going towards the transmission (gearbox) and I am pretty sure I should keep those.

Does anyone have a schematic of the heating plumbing or able to sketch it out for me and email it?

Thanks

Hi Lorne

There should be a diagram in the Walker's Routemaster manual I believe you mentioned you have one in a previous post.
I don't think there is coolant for the gearbox, unless you don't have a original gearbox?
Photos would help diagnose...

I can't remember the details of your RM, but was it fitted with additional heaters along the sides ?

Yes, RM2133 had heaters down both sides of the upper and lower saloons.

On the engine bulkhead, just under the spring hinge on the bonnet is a squarish cover that has what looks like a junction for coolant to go into the lower saloon and another pipe which runs down and under the chassis on the nearside and heads towards the rear. I have not had a chance to crawl under and trace down where it leads but if it does not go to the gearbox then I think it can be deleted.

Got it all sorted. I was confusing an electrical conduit for a plumbing line. Pretty simple once I was able to clear away the snow and crawl under and have a look.

Thanks for the help
