heater hose
Hi all
just a quick question about heater hose
ESM list 2 types 59" and 36" lengths
the 59" is for an early rad take off
my Morris is a 1960 model would i be right in thinking the 36" one is right for my motor??
cheers

Re: heater hose
I'm thinking the longer hose is for the earlier rads where the heater hose connects to an outlet on the bottom corner of the rad and runs along the engine bay floor, before running up and into the bulkhead. The later types connect to a pipe running across the top of the engine by the rocker cover. I don't know exactly when the design was changed but if you haven't got the early rad with a heater take-off at the bottom left (looking into the engine bay from the front), then I think you need the 36" hose.

Re: heater hose
I've just had a look at my copy of the AKD 3542 and there's a lot of different car numbers, but I think it boils down to, as you say, the introduction of the fixed pipe along the top of the engine.myoldjalopy wrote: ↑Tue Nov 01, 2022 10:18 am I'm thinking the longer hose is for the earlier rads where the heater hose connects to an outlet on the bottom corner of the rad and runs along the engine bay floor, before running up and into the bulkhead.
The Parts list gives the different lengths, but you can see it was just supplied in bulk for dealers to cut as required, as there were no part numbers for the different lengths

Re: heater hose
I just buy what I need by the metre, it's available from most car parts shops in big coils (if one can still find a proper car parts shop). Cut it to whatever length you need to get a neat route.

Re: heater hose
The original pipework meant that a cold engine (ie thermostat shut) with the heater water valve open replaced all water pushed through the heater
with cold water from the bottom of the radiator, thus partially negating the function of the thermostat to ensure a fast warm-up. I can remember reading years ago various articles advising owners to change to the modern layout, thus ensuring faster warm-up.

Re: heater hose
Additionally, for anyone who doesn't have one already, you may like this tool:

It's much better for cutting your new hoses to fit more easily and squarely, than say with a Stanley knife or hacksaw.
Best wishes,
Mike.

Re: heater hose
I’ve never bothered with a tool for a specific job, like this, unless I was a regular user. I don’t consider cutting the odd coolant hose as a specialist job.jagnut66 wrote: ↑Sat Nov 19, 2022 3:52 pm Additionally, for anyone who doesn't have one already, you may like this tool:

Generally a stanley or hacksaw has been good enough for cutting hoses. For the rare event of needing ‘neatness’, I would just put the pipe over a suitable piece of round bar, rotate under a felt tip pen to mark the cut and follow that line with a stanley - to cut part way through - and then finish off after removing from the pipe. One less tool to hang, unused, on the wall or eventually in the scrap bin. YMMV from mine - I expect you have one?

Yes, I have one, I have used it a few times now and never regretted buying it. Cut's straight through, neat job, good fit, job done.
Then, as you say, it's ready in the cabinet drawer for next time. I've not noticed any rust yet.
Best wishes,
Mike.
P.S. Here's a cheaper one:

At a guess, I would say he means 'your method may vary'
