Heater motor ideas needed

Recommended Posts

Wanting to fit a heater to my 88 coiler. Running a 200 Tdi.

I've got hold of a 90/Defender style heater core/box, but what I haven't got is any sort of fan/motor or cowling. My original thought was to just use a standard Series motor assembly, they aren't the best, but adequate for a pickup. And obviously come with the ease of installation.

But the motor assembly and snail cowl seem difficult to find. I couldn't find any repro one. And original ones seemed to be silly money for what they are. I did acquire a couple of used ones, but they were too far rusted to be of any use.

So I'm looking for ideas and suggestions.

 

The only squirrel cage fan I can find is this one:

But it looks like it might less powerful than the stock Series one. Something with a round outlet would also make plumbing it in easier. Anyone know of any donar vehicles that might have something I find used or other options?

Dredging up from memory there is a Suzuki fan that is similar to the LR one - can't remember the details.

Beware of after market ones, they're often more asthmatic than 50 year old green oval stuff. I have one that looks just like that ebay link you've posted.... It's absolute garbage, I can breathe harder. 

I've hunted high and low myself for the same thing and come up short. I ended up re-orienting the defender fan on my series fitment, which works fairly well. Complete heater/fan assembly's are easy enough to get hold of, so that may be an option?

That was my concern, have been putting this off since last winter. Must get on and finish it though.

One thing I've learned through much messing with low volt DC motors: size does matter. Ignore the marketing garbage, if it draws < 15 amps at 12v (180W), it's not going to do very much of anything. If wattage or amperage aren't quoted, have a good look at motor size. The little chinesium pancake things that end up in just about everything are a total waste of metal. 

The suzuki fans looks very promising. Constructing a snail housing might be the challenge there.

would it not be better to fit a diesel heater? by the time you have reworked half the engine bay you have spent some time and money for a not fantastic (excuse the pun) result.
