We have a 1991 240 with the dreaded squealing fan. Can't do anything without it making terrible noises.
I have searched around but maybe not in the right place.
Until we can dig into the dash and do it properly I have been told there is a certain access point where I can at least put a drop of heavy oil into the bushing to quiet it down for the short term.
Question is, where/how do I access the blower to do this?

"I have been told there is a certain access point where I can at least put a drop of heavy oil into the bushing to quiet it down for the short term."
The locations for access to the bearing are approximately under the 2nd plastic pop out from each side.
Initially, you may find it easier to remove the console, move the wires out of the way, drill large holes (eg. 1") with a hole saw, vacuum, oil the shafts by the bearings, cover the holes with duct tape (or plugs if you have them) and put the console back, maybe repositioning wires and switches in the process. Make sure your ground wires are all attached. Maybe an hour and a half taking things easy?

Hi!
In order to get to it, you are into it, period.
I added small plastic tubes to my first and oldest car some 30 years ago. It still has the original fan and get its felts oiled about every ten years. But those motors have a large aluminum housing.
I made it so I could lube it from the upper vents area by removing them.
As I said, It still required removing the fan and figuring out how to salvage it by cleaning up the bearing bores.
Drilling holes into the end bells to lube the felts and fishing the lines up out and through the motors enclosure or plenum.
It is quite a project requiring days to plan, implementing those and pulling all the incidentals back together.
Take plenty of your own pictures for details and do good research.
Get your head into planning a weekend.
Not all new fans have a chassis as conducive to making great modifications to or as anyone would like. It one of the hardest or longest job you'll ever do just to change out one part.
It will save you upwards from $800 to do it yourself.
If you still decide to tackle this, there are lots of pictures.
The methods of installing aftermarket units here and other web sites.
The motors are made of punched sheet metal with very limited access to the hubs containing the felts and adding tubing into those spaces can difficult but is do able.
Some better motor manufactures will have their own drip tube channels paths. Maybe you can find vinyl tubing to fit into them.
It only helps when the fans mounting holes allow the slant of gravity to work with those tubes to the felts.
Shop carefully as stock changes.
If you buy one of them make sure to add better lube oil. To me they are shipped way too dry for hazardous material reasons I guess?
That about all I can tell you. You will have to work as hard as you think it will be worth it.
I'm sure a lot of us just throw the motor in and call it good until next time!

Alright, thanks everybody for the info.
Funny thing is that I have a 1984 240 with about 230000 miles, I was told that its fan was noisy and lubed and it is fine now.
My son has a 1991 240 with about 295000 miles and the newer car has the squeal BAD.
I figured a quick fix was too good to be true so I guess we will set aside a Saturday and get to it.

Take that motor apart and tell us what you find, please.

hi machine- so if i read you right, it appears its the same amount of long and hellacious work to lube the fan or replace it. ran into two shysters while anticipating this job on my 245. local indie wanted $800. dealer wanted $1k. luckily mine is still working. if worse comes to worse, thinking of small dash fan like on big trucks to put wind on the windshield and or suck heat out of the ducts. this ought to get the oscar or medal of honor for most stupid auto engineering design of the century. even beats the hydraulic clutch and interference engine which were big contenders. thanks tons oldduke

Greetings OD!
No, the Volvo interior fan on 240's is probably the worst! The rest of the car is built around the fan...:) If it is any consolation, I understand that the 740's and 940's are just as bad. Years ago I remember my friend Ed replacing his fan on his 86 740. Parts were scattered everywhere!!
On a serious note, to maximize the lifespan of your 240's fan try using the fan little as possible. One other other thing you can do is avoid using fan speed setting #1 as much as possible. Use fan speed #2 instead. The fan will run cooler. As I understand it, the reasoning is that using fan speed #1 creates more internal heat than the other settings. So simply avoid using it! Using this strategy, I ran my 90 240 to 300k (when I sold it) without replacing the fan.

No, the blower fan on my 740 was a breeze! It took me a couple hours, and all I used was my Makita battery-operated screwdriver- with 80 bits(I needed about 12 of them ,as I recall).But it's located on the passenger side just under the glovebox.But it's a 92.Maybe Volvo had some mercy by then. I saw an exploded view of the 240 blower motor in the Haynes manual and I nearly fainted! Which is why my old 240 wagon of years gone by,had no heat . I guess if you were to attempt this job, take pictures,as suggested,and plenty of notes.And a box of ziplock bags and label the heck out of stuff.Even a voice recording wouldn't be a bad idea,neither would a Valium.

hi jw- just a quick note. during a similar discussion of this item a few yearsago on this board, a poster commented that the position of the fan motor was redesigned in the 740 model which made r and r much easier and quicker. rgards oldduke

The fan motor is not the worst, and no, the 240 is not built around the fan motor!
The first part on the assembly line is the heater core which is then magically suspended in mid-air while the heater core assembly is placed around it, and then the fan motor is installed to that assembly. The rest of the car then follows.
So no, not the most hateful job out there, but a very, very close second.

It makes me fell better to here that, it took me hours and it's only together enough to have defrost and safely drive. I am having secc
ond thoughts about replacing rear shocks myself, advice?

Mine was doing same thing a few years ago. I stopped using it unless I had to and then used it mainly on low with short uses on middle setting. It stopped squealing unless I put it on high but then after a while i could put it on high with no noise. I still don't use high. This might be one way to prolong its complete failure for now.

1982 245. One of these days i expect to have to do the heater core. Ordered a new one sitting on the shelf in the garage till that day comes. Ever done one? how hard and how long? found directions on some volvo site a couple of years ago and it looks like a biggie. wish i had done it when it did the fan motor.

You are correct. The fan is second. I was thinking of the heater core.
Amazing how Volvo was able to suspend the heater core in mid-air like that...:)
