Replace fan motors?

The 308 radiator fans are easy to refurbish. Remove the grill & fans noting wire connection positions and roughly note their position regards distance to the radiator and housing rotation (not critical but saves head scratching upon replacing). Removing the horn may be necessary. Spread the mounting clamp a bit and hold your tongue right to get the fan through the opening with blades intact.

If you are squimish about working on the motor you may wish to oil the bearings to end the motor noise at this point but I would encourage you not to quit here.

Remove the motor shell (2 screws). Inspect the brushes and replace them if necessary (I needed to on one fan). Small motor service shops carry brushes for about $10/pair and they can advise you about necessity if you are uncomfortable here. Clean and re-oil bearings with 3:1 oil.

Replace the clamshells and adjust the endplay screw if it has one. Use a 12v source to test each fan, noting the rotational direction for pushing air. Replace the fans, horn, grill. And when you get them going again do an operational check.

I.e. double check the direction of the fan blades to insure they are indeed forcing air INTO the radiator. Reversing the wires at some point in their history is not out of the question.

Assuming no brushes are required its a 2 hour job at most.

 

Hi Seamus,

Here's a thread that started where you are. I ended up putting my fan rebuild in it. The pics might help.

Good Luck,

have you given any thought to installing hayden fans? they move alot more air and i think the cost is about what you'd pay for motors. there's a thread about it.

 

GT auto parts had brand new ones cheap

I did it the real cheap way, but its great, A trip to the junkyard, a walk to the fan shelf,and found some nissan pulsar fans, the same dia. motor as the ferrari clamp bracket ,and a really much bigger set of blades , alot more pitch, they really move twice as much air,it seems to run cooler for a longer time.Easiest job i ever did!

 

I replaced mine with SPALs. I also added a puller fan to the oil cooler in the engine bay. I had to make some mods up front though, removing the stock brackets and fabricating new ones, as well as removing the shroud from the SPAL fans altogether. They cool much better because they produce SO MUCH more air flow over the stock fans.

I put new modern 12" pusher fans on (shock, horror!). Worked magic for cooling on 115 degree days.

 

You just have to tap it hard...they come off....it's the same motor as an XKE Jag V12, it's Lucas....my guys found it for $129 plus tax thru Worldparts or someone like that.....

How much at GT Car Parts?????

 

One more thing on the modern fans. They push about three times as much air as stock fans, and they draw about half as many amps as the stock fans.

 

I removed my stock fans, and replaced with 2 new Spal fans. I bought the biggest Spal fans that would fit, and had to remove the fans from there protective valance in order to make them fit. I had to remove the stock mounting brackets and fabricate my own, but that was relatively straightforward.

The new Spals push a tremendous volume of air over the radiator, much more so than the stocks ever did. I also added a puller fan to the rear oil cooler, which works off the same relay as the front fans.

Here's the link to the thread where I have some pictures: http://ferrarichat.com/forum/showthread.php?t=35703

They may work better but I try to stay OEM if possible....search the parts exchange sticky thread , or I still have my box lid somewhere....moving right now though.....

 

Now, here's an area that I'm very well verse in -- Jaguar XKE auto parts. Having owned several of them including a Ser. III V-12, I've dealt with the Prince of Darkness and fan issues on multiple cars.

There are several good suppliers for Jaguar parts, and price shopping is encouraged: SNG Barratt (New Hampshire), XK's Unlimited (California), Welsh Enterprises (Ohio), Coventry West (Georgia? NC?), to name just a couple. And there is a guy who has been making specialty products for the Jaguars, and in particular fan upgrades for the XKEs. His website is: www.coolcatcorp.com. Not sure if he is doing Ser. III fans, but it is possible his Ser. II fan upgrade might work on the 308s. I have used his fans on several XKEs and they are truly excellent, move much more air than the stock fans.

BTW, Do you know why the British drink warm beer?? Because Lucas makes their refrigerators. And now for the Lucas jokes......

 

Seamus,

You can't go by the part numbers. The numbers used by those websites are usually the Jaguar parts numbers, not Lucas.

That is the Ser. III fan motor. The Ser. III motors are pretty durable. Most of the Ser. III cars I know of, and the ones I've owned, all had original fans and they worked great. The new ones are good quality too.

I didn't look closely at the Ferrari fan picture, but this fan motor goes into a compression mounting bracket in the radiator shroud. It does not have an integrated bracket on the motor housing itself. You also need to check that the fan blade will mount up as well on that shaft. And the connectors on the motor are an old fashioned "button" type snap together connector, so you might have to change that was well, but that's not a big deal. I'd suggest using a push-in connector so that you can switch leads if necessary to reverse the fan direction.

 

Yep, note even the wire connectors and note on polarity are the same........true enough if you reverse them it runs backwards.....I played with mine on the battery for awhile.....

Bushings were shot.

 

That is the EXACT same motor...I'm telling ya, it went right in......that's about what I paid also to my friends at European Cars, Ltd here, the Jag shop wanted $250 which I guess is retail $$$$.

My buds passed it thru at cost with tax added.....

 

black is hot, green in ground.....hard to go wrong there!

 

On my 1985 308gtsi Qv, I am going to replace my OE fans with the Hayden fans. I was looking for the thread on installing Hayden fans, but have not found it. Anybody know where to find it? Thank you

On my 81 GTSi i also went the Spal way.
Since i had my AC compressor out for about a year i now removed the condensor in front of the radiator.
Made mounting brackets to fit the mountingpoints of the condensor.
The biggest fans i could fit where SP30101505.
This works great, my 308 never stayed this cool.
