Help Please - Installing a round 'Smiths' heater into a pick up

Post by RichardJay »

Hi all

I need to install the round Smiths heater into my 1965 Pick up (see pictures of heater)

Would anyone be kind enough to send me some pictures or a video to show how it looks when its installed correctly. For example, is it screwed into the floor? (using the holes in picture 2). Is it also bolted just under the speedo (using the bracket above the 'SMITHS' logo on picture 3). How close to the bulkhead does it go?

Also in the engine bay, on the back of the cylinder head, is there a brass tap or is it a continuous flow system

Many thanks

Richard

Hi,

Your heater has the additional "fresh" air vent on it.

The lower part of the trunking will detach and contains a flap controlled by the cable.

Once that is removed the cowling round the heater can be separated if desired leaving the round heater.

The bit that bolts to the floor/lower bulkhead is designed to go over a hole cut in the car so that it will take in "fresh" air from behind the engine.

From personal experience I wouldn't cut a hole for it in a car that doesn't have it. I would either fit the heater without the cowl, or if I wanted the look fit the cowl but still not cut the hole in the body.

I am not sure what water valve would go with the age of your vehicle as I am not concerned with originality. There are brass valves with a tap (little wheel) operated from under the bonnet, a more modern cable operated valve (which can be a source of leaks) or a fixed spigot so you cannot turn the hot water off. Some have said that this is preferable as it maintains water flow through the cylinder head. Though mine is currently running happily with no heater and it blanked off.

If you have no heater at the moment you will also need holes for the water pipes and the radiator hose with a fitting for the heater return pipe.

Sean.

If you go to the home page and the downloads topic you can look at the workshop manual

member_downloads/workshop_manual.pdf

Section S and SS cover the heaters.

Its near the end so quicker to start at the back (CTRL and END will jump to the end of the PDF) and scroll up :D

This is the hole in mine.
