Heater blowers

Recommended Posts

The heater blower got totalled on my V8 in the accident by the spare wheel crunching through the heater plenum cover:

To be V8 specific first, then we will have a look at the other models. From the parts manual:

So it's an A082M6619F. Available from a reputable Lotus spares supplier at £150-ish inc VAT and delivery:

 

HEATER BLOWER MOTOR V8 only
A082M6619F     EACH     108.68

 

I didn't really want to pay that much for what is really just a fan. Although it is a three speed one. Let's go on the hunt. The label on the damaged one is:

 

SPAL 009-A22-26-D 12 volt

 

Good good, SPAL is still a major supplier and trading. This particular unit looks as though it is no longer available unfortunately. I found a cross reference at http://august.en.gasgoo.com/auto-products/1942064.html:

Thus a SPAL 009-A70-74D 12 volt (they come in 12V and 24V variations) is the later alternative. Bingo, a current supplier:

£94.62 inc VAT and delivery. That's saved me fifty quid then! On receipt I checked it against the damaged one and all is good.

 

What about earlier models then, would this one be any use?

 

The '93 on parts list has an identical picture (with different item numbers) to the V8:

Curiously the part number is different, COB2M6358F? The reputable supplier lists a completely different number too:

 

HEATER BLOWER MOTOR Four cylinder only
A082M5077S     EACH     144.64


The price is £190-ish inc VAT and delivery (£150 for the V8 one from them?) So I'm not sure what is going on here. My gut feeling is that the V8 item should fit but it would be sensible to check out the manufacturer's label - presumably SPAL - on the blower to confirm.

 

'88 to '92 is exactly the same as the '93 on, including the parts manual number, so the above would apply here too:

Earlier Esprits have a completely different setup with two motor/fans, although they are the same part number for '80 - '87 and '76 - '80, A075P6056F and A075P6058F (the fans rotate in different directions):

post-18669-0-56813700-1431080084.jpg

 

I haven't done any work trying to source these earlier ones as it is difficult without a manufacturer and part number reference.

 

It's a breeze! :harhar:

Thanks Malcolm, that's interesting. Hmmm. I'm beginning to think that possibly my SPAL might be an upgrade by a previous owner? The original would look more like the parts diagram, plus the post '86 GM association makes sense.

 

If '88 on Esprits do use the Nova motor then it would be this one presumably,  http://www.vauxhall-car-parts.co.uk/acatalog/VAUXHALL_HEATER_MOTOR_-_90227051N.html:

...and only £66 inc VAT.

Update

 

My friend FinalEdition has a blower for sale from his V8 development car and it is the same as the broken one on mine, the same SPAL fan and part number:

post-18669-0-75282900-1431332458.jpg

 

So I think this begs the question as to when/which model Lotus swapped over to SPAL and I guess whether these later fans have the same mounting as the earlier cars and hence would fit?

Ok, I just so happen to have a Vauxhall Nova on my drive that I bought for my daughter who has decided to buy her brother's Corsa instead. Ho hum. Anyway, I'm refurbishing it to sell (1991, 1.2 Merit 5 door, Mexico Red, 43k miles, two lady owners from new and completely original, spent a fortune on parts to get it like new, if anybody if interested :-p )

 

So I had the heater blower cover off just now and took a couple of pics:

The GM part number for the assembly looks like 22030973 or 4343924. I will check that out later. It definitely tallies with Malcolm's comment.

 

Perhaps Lotus swapped over to SPAL in 1994, as the Nova ended manufacture in 1993? Could any S4 owners enlighten me?

The resistor pack on my new SPAL fan burnt out on the way to the MoT, filled the cockpit with smoke apparently (still haven't got the bloody car back, that's seven months...). Duh. Will send it back for a refund.

 

Anyway, I found the UK SPAL office: http://www.spalautomotive.co.uk/

 

Plus the manufacturer's spec: http://www.spalautomotive.co.uk/product/009-a70-74d-2/

 

And these guys who are SPAL distributors (useful for axial rad fans too, as well as air con stuff I guess): http://www.southernsales.co.uk/

 

Plus this chap on eBay who has a few in stock at only £61: http://www.ebay.co.uk/itm/009-A70-74D-SPAL-Centrifugal-Blower-12v-3-Speed-Fan-/191588662439, that's where I'm getting mine from.

 

Interesting to note that the blower unit is also used in the TVR Cerbera!

TBH, the fan output on my car is not that great, so I wonder if there is an upgraded unit that would push a bit more air?

Just realised I could have experienced the quality of blow in your cockpit while we were at Brooklands.

 

T7 Design -  I've had dealings with that guy before professionally. He's pretty good to deal with, and very helpful.

I'll take the cover off to see what I have fitted before I go spending, plus it will help pin things down as to what was fitted, model and year-wise

Just taken the cover off, and it's the GM Vauxhall Nova jobbie.

My car VIN shows October 1995.
