Malawi 110 Why does the heater blower not work? 

Thanks, will do!

Yes time is money - the blower is C$369

I now put captive nuts in the footwell where the bottom nuts and bolts should go - - now a one-man operation and a lot simpler!

@@BritannicaRestorations good idea. But I'm hoping not to be switching heaters too often. Your suggestion is probably also worth considering elsewhere on the Landy. Thanks

Cheaper than a blower @ £145!

The Eberspacher heaters and their various copies (including Chinese) have the advantage of using on,y a tiny amount of fuel for a decent amount of heat. They don’t need the engine running, so save on engine wear, fuel and noise. Besides, the cabin heater overcools the engine at idle in temperatures of less than 10oC, so are not much use for stationary vehicles in Arctic conditions!

Very cool!

Yes the blowers are so expensive for what they are C$369!

Best of luck!

Go for it!

The 300Tdi matrix is the same size as the Td5, but with the hoses in a different place

Hi Mike, no, pipes same as 300tdi but has a better core, the biggest prob is that the top and bottom tanks are larger so the openings have to be enlarged, but its worth the effort , my window demisters now work....

It’s not the design that made a difference but the fact that it was new and unclogged with sediment, scale or corrosion.

Roy - it will be a good long while until I see one of them here - still have hardly any Td5 here! lol!

Yes you could

@@BritannicaRestorations so did you?

Problem is getting the plastic fan off without destroying it - the shaft rusts and expands the plastic - there is nowhere to pry it off - and if you warm it and lucky to get it off - then refitting is a nightmare as the shaft is now sanded down to get the cover off - you just cannot win! You could buy the fans separately but not any more

@@BritannicaRestorations yes of course, the old Jag fans were all steel Smith's units, with a type of metal collet fitting holding fan drum to the shaft, "ah, them were the days", pure luxury...

Rust!

Thanks for watching!

@@BritannicaRestorations no thank you! Hopefully it won’t lead to alcohol, Cocain and Ketamine 😅😅

Glad to hear!

This why I had go at trying to vibrate a bit of light oil into the bush - it turned, but not good enough

22 is a great age to own your first Disco. You can have the rest of your life to either love them or to get over the experience....

Lol!

Yes it was!

Take off the instrument binnacle and swap the wires over on the back of the heater switch (green yellow, green purple) The blower will now work in position 2 but not 1 I would wager the resistor has blown in the heater blower - this is fitted to reduce speed on the position 1

No problem 👍

Yes they are expensive for what they are But if you think that was expensive look at the motor price! www.paddockspares.com/utp1911-heater-motor-and-rotor-assembly-rhd-from-la939976.html

@@BritannicaRestorations As It happens I did as for the last 20yrs I have always had the fan running on speed 1 unless I run at 2 but never off. I though I'll bet those carbon brushes will be at the end of their life. Just on with refurbing the pedals and doing brake lines, Heater will be next of new B/C pillars, I'd like the get them and fit at Easter, so don't forget when you get 5mins about distances for the C to rear tub measure please.

Marine bilge fans work well.

Sounds like the bushings are getting tight

Actually when they are working and not plugged up, they are not a bad heater - the thing that lets then down is the coolant is not hot enough and they pull cold, ambient air in When Jim and I were out in my 130 last weekend to pick up some furniture it was like an oven in my truck - I draw the air in from the footwell floor and the Isuzu puts out more hot coolant than the Tdi - it was too hot on the second speed!

don't bother: my series with a 45 year old heater core works miles better than my 300tdi ever did! Also the way the motor is integrated in the housing is terribly clumsy.

Look up T7 (or is it T17?) Design for upgrades if you must. Series split heater and fan and our series had a better heater than our 90!

I've got an old 'Smiths' heater in my Series II cab, it's a larger rectangle one, probably military. I've seen smaller round ones too in other series vehicles. (It's a heater core / radiator in a box with a fan, goes in the cab, hooks to flow & return pipes from coolant system) Advantage: Can be placed wherever you have room in the cab. Disadvantage: There is no room in the cab to begin with... .. :D

I did exactly that and have a very good heater as a result. But it might be just as effective to recondition your existing blower (similar size, so probably similar airflow) and replace the heater matrix with new. Then just go around filling the holes in the casings, the lower fascia (usually got rust or screw holes from some accessory or bodged repair in the past), ensure the demister vent hoses are in place, the large grommets that seal the lower fascia to the demister hoses are in place, and replace the corrugated plastic hose from blower to matrix, as they get very brittle with age and split everywhere. On the water side, remove and clean out or replace the steel pipes along the head, the valve and various connections, and check the hoses. With good airflow, good coolant flow and correct control adjustment, they work pretty well for European winter conditions, even in a 109. The Defender type’s principal difference is how the temperature control works - it has an air diverted flap that directs the fan air through the matrix for full hot, around the matrix for cold, and wherever needed in between, while the SIII type has all air go through the matrix and the temperature control restricts coolant flow through the pipes. That means the Defender type responds more quickly to control changes, has less restrictions in the coolant pipes as is lacks the coolant control valve (also less likely to leak or seize), and can blow cold air faster as it is unrestricted by the matrix. But it is a bit of a faff to retrofit, mostly because of the blower intake position (won’t connect to SIII wing intake) and because you need to reverse the wiring polarity (simple enough).

Yes they are not cheap - C$369! just the blower!

Not even as cold blower!

@@BritannicaRestorations It gets down to around 6 degrees C in Malawi in winter, and parts of the country see frost. It's not as hot as you might think, and a bit of heat would feel alright in 6 degree weather.

Call that snow?! Why it's a mere frost! Lol! Looks good

@@BritannicaRestorations Even by my own experience elsewhere, that's not a lot, but it was enough to paralyse most of southeast England. Anyway, it gave me an excuse to send you another photo for your wall.

LoL! Mike

Problem is if it sticks again after a few weeks which it may do in this case - usually a soak with oil gets them running again

@@BritannicaRestorations the warmth usually draws in the lube. We have the same issue with maraine engine-bay blowers on 12v system. The brushes stick and a good "kicking" usually sorts them out..

I was contemplating a cheap diesel heater to fit in its place - 90 is a bit tight for space

@@BritannicaRestorations I was tempted to fit in in place of the centre seat, make a new centre seat box cover with the holes in it for exhaust etc. then it can be a modular thing that I can take out in the summer and put the seat back in...

You can get a box that the heater fits in below the cubby but it is expensive I designed one but the cost of production was too high

@@BritannicaRestorations Yesterday I ordered a new centre seat cover from YRM - I was not willing to cut up my original. I am going to mount the heater to that, then I am going to copy the heater box you speak of. The one from Mud? I currently have the centre seat, quite like having it but in reality I never have 3 people in the 90. So I will remove that and look and getting a cubby.

Yes Mud do one that's why I gave up on my design - but it was a lot better!

lol!

Electric is a waste of time in Defenders - too heavy, short range - and what do you do for heating here in Canada?

Probably not, but might be needed here!

Me too - I had lots of Sprints back in the day - head problems etc!

They’re not bad if they’re clean and correctly set up. I get a lot of heat out of my standard Defender heater with a 200Tdi once the engine is warm. Certainly ample for UK conditions while driving, but the heater overcools the engine when idling. For Arctic conditions, a parking heater or something like a Webasto Thermotop would be very useful.

lol!
