Hi Adam . This brings back memories ! Back in the 1970's the dynamo pulley shattered on my Triumph Vitesse and in the process broke several fan blades . I was 100 miles fom home, it was Sunday afternoon ....what could l do ? I managed to remove the remains of the fan so it wouldn't shake the water pump to destruction and persuaded my girlfriend to remove her tights so l could make a belt from the crank pulley to the water pump ........it worked ! We got back home before dark so didn't get a flat batttery !! No idea why but my girlfriend didn't want her tights back !🤣🤣🤣🤣

I was traveling in my 85 Cutlass, When I pulled back on the highway after stopping for gas, it wouldn't do over 45 Mph. If I tried to go any faster the little 260 V8 would ping a little like I was doing a hill climb. At first I thought I must have gotten some bad gas but, when I checked under the hood, I noticed the fan seemed to but blowing more air than normal. I shut off the engine and found that the fan clutch had seized up. I was amazed at how much power that fan pulled.

I posted this so many times on the forums! Whether you see cracks or not just change it! I used to check mine every time I drove my car. One day I checked it and it was perfect, drove it to a car show 15 minutes from my house, opened the hood and it was starting to crack!! I limped the car home and changed it on the spot. If it had been a long drive I probably wouldn't have made it home! Thank you for the video.

As predicted, I'm going to advocate electric fans for anything that doesn't have a thermosyphon cooling system. Manufacturers always err on the side of caution, and fit fans adequate for noon-day traffic jams in Lagos. The result is usually overcooling in temperate or chilly climates, (and a prodigious waste of power). For a large-ish radiator, a 2-fan setup provides some redundancy and more even distribution of cooling across the core. Plus, if the fans are in front of the radiator, the engine bay is less crowded.

I agree, electric fans are better for all the reasons you mentionned. My other car, a 2008 Mazda 3 had the e-fan module broken (bosch...) when I bought it and I wasn't aware of the issue for 3 months, because it didn't overheat. It was until I was stuck in a Montreal traffic jam... All was fine, as I knew about turning on the heat and opening the windows and the small overheating issue resolved itself. Then I replaced the module.

Not just Jaguar. I had the fan on my 90 Volvo break an it took out the radiator. Luckily the car was already in the shop after having the alternator replaced. Right proper pain.

In the 1960's I was a teen working in my dad's garage. I remember he was called to give expert testimony in a lawsuit. In the case, a do-it-yourselfer had been killed, struck in the head, by a broken fan blade while changing his water pump. I think my dad was called by the widow's attorney but, now wish I'd asked him, if it was a faulty part or if guy had messed up. I had assumed it was metal fatigue but maybe the guy assembled it wrong, dropped a tool or something.

Adam, it would be interesting to do a video about where to get Jaguar parts. At the moment, I use eBay, but I wonder what are the options available.

I've seen a metal fan blade come through a bonnet years ago on a 60's Triumph 2000. The mechanic was just giving it a rev after road testing it and was shocked saying that he was only leaning over the engine a few minutes back and was revving it up to warm the engine. I remember the blades were an unusual design being riveted onto the drive hub on these cars.

Have no idea why but l think a similar incident happened to a mechanic at South Devon Garages on a 2000 in the early '70's.

Thanks for this video, I've just checked mine and it has a few cracks in it. I've hacked with the usual Jag suppliers here in UK and new fans are no longer available. Will be keeping my eyes peeled for a good second hand item :)

One reason for the fan to fail is the viscous fan clutch being stuck as you mentioned on the video. In that case only the slip on the belt saves the fan rotating at excessive RPM. I'll keep mine mechanical, it is good to have one electrical and one viscous clutch operated so that there is no single point of failure.

Thanks for the video Adam

750 IL fan explosion killed the front of my ride.

Hello, sir! I apologise if this is a silly question, but how do you stop the fan moving while trying to remove the 4 bolts? I need to change my alternater belt as its currently split into 3. The fan bolts have lilely never been removed since 1989 by the looks of it. Thanks in advance!

Doesn't Jonas Loda make an electric fan that replaces this?

I'm surprised someone has not made a replacement fan made of steel. As you said if the fane "explodes" it can do some real damage.

The steel ones can do the same thing also

Thin steel may be even more prone to cracking than good quality plastic.

where can you find the better fan?

and does it go on the 4L engine?

I converted my XJ40 to electric fan and it is happy. Now I can hear the engine; not just wind noise. Also, the car is slightly quicker to accelerate from stops. I'm an electronic tech (industrial automation) and I know my setup will be reliable. Even more, the XJ40 already has an emergency electric fan.

Wow, a car that really genuinely actually has a “ fan belt” ! I have to say though that the replacement fan looks like cheap generic Chinese Amazon crap… I hope I’m wrong !

It’s sold by all the major Jaguar places so it should be fine.

My 1990 Volvo 240 has 3 proper fan belts. One for the power steering, the other two for the alternator. When I add air conditioning, that will be belt number 4. When I needed a new fan I was lucky. IPD USA sells them new along with the fan clutch and all the hardware. I had a spare old one, but feel much better with brand new.

It's probably a good idea to inspect the fan on any older car. The High rotation speed could cause stress fractures on any item that is decades old. It is not a pretty sight whe one let's go. Ask me how I know!
