Hello Alexis,My name is Andres and i will help you with the problem that you are having There is no tensioner per se on the 240. The tensioning is done by moving the alternator. At the top of the alternator there is a tensioning arm with an elongated hole in it. There is a square necked screw which goes through the arm and fastens to the alternator. At the end of the arm there is an adjusting screw. As you are removing the alternator forget about the adjusting screw. Slacken the nut on the square necked screw and push the alternator to the side, releasing the tension. If the alternator won't move, loosen the flange screw underneath the alternator until it will. With the belt off remove the wires from the back of the alternator, making sure you know which goes where. Remove the two bolts you have loosened and remove the alternator. HAVE IN MIND THAT There is a problem on the older 240 series, 1984 B23F I know from personal experience, with the ground not being intact between the alternator and the metal grounding point. Please check the wiring loom before you re-install your new alternator for a good grounding wire, or you'll be wondering why your Swede won't crank when you've just replaced the alternator. If worst comes to worst, you can create a temporary ground for the alternator with a piece of copper wire. Connect one end to a good unpainted ground near the alternator(strut towers will do), and the other to the attachment bolt on the alternator mounting bracket itself. This will suffice until you can get it properly fixed

    The only problem is Andres, is that it's a 244 series 1984 Volvo. Not a 240 series. Would you know how to adjust the alternator on that specific series

the engine stabilizer brace.

Applies only to B6xx4T engines:
Remove the plastic pipes between the turbocharger (TC) and charge air cooler (CAC) and between the air cleaner (ACL) and turbocharger (TC). Put them to one side. Remove the clamp from the intake manifold for the turbocharger (TC) for cylinders 1, 2 and 3. Turn the upper section of the pipe towards the firewall.

Relieve the load from the belt tensioner.
Remove the auxiliaries belt. See: Drive Belt\Service and Repair
Remove the upper timing belt cover.
Remove the front timing belt cover.
Lift up the servo reservoir and place it on top of the engine.Note! Ensure that the oil does not leak from the ventilation hole in the filler cap.

Disconnect the hose at the tank.
Lift up the expansion tank and place it on top of engine.

Raise the car. Remove
the right front wheel
the plastic nuts on the cover in the fender liner. Install the upper timing belt cover.
Turn the crankshaft clockwise until the markings on the crankshaft and camshaft pulleys correspond.
Turn the crankshaft a further 1/4 turn clockwise. Then turn back counter-clockwise until the markings correspond.
Remove the upper timing belt cover.

Remove the 4 vibration damper screws. Counterhold the crankshaft central nut.

Remove
the vibration damper
the auxiliaries belt
the belt cover behind the crankshaft pulley for the auxiliaries belt. Spray universal oil or similar around the rubber sleeve on the underside of the oil pump.

Remove the rubber sleeve.

Removing the timing belt

Slacken off the belt tensioner
Slacken off the center screw for the belt tensioner slightly.
Hold the center screw still.
Turn the tensioner eccentric counter-clockwise using a 6 mm Allen key.
Turn to 10 o'clock.
Unhook and remove the timing belt.Caution! Do not turn the camshafts or the crankshaft when the timing belt has been removed.


Checking the tensioner pulley and idler pulley Check bearing wear:
Spin the idler pulley and listen for noise. If replacing with a new idler pulley, tighten to 24 Nm .

Tensioning the timing belt

This adjustment is carried out on a cold engine. A suitable temperature is approximately 20°C / 68°F .
At higher temperatures (with the engine at operating temperature or a high outside temperature for example) the indicator is further to the right.
The illustration shows the position of the indicator when aligning the timing belt tensioner at different temperatures.
Carefully turn the crankshaft clockwise until the timing belt is tensioned. The belt must be in tension between the intake camshaft pulley, the idler pulley and the crankshaft.

It is possible you are looking at the page for the 1994 960 and not the 940. The 960 had one (serpentine) belt. Your 940 has three. Hopefully chiltons has the repair order for the 940s as well.

I know it's not alot, but I hope it helps

The belt goes to flywheel, radiator cooling fan and alternator. It does not go to a/c depending on what engine configuration.

Loosen the bolts underside of alternator and then loosen the tension arm alongside the alternator. After replacing the belt, use a piece of wood a suitable length and size to re-tension the belt whilst tightening the tension arm then tighten the lower bolts.

Check to see if there is a tensioner pully that adjust the belt tightness. The tension pulley a small pulley will have two bolts on it one of them loosens and tightens the belt around the alternator and compressor USUALLY.

Hi,
Unscrew the idle pulley first.
Look for a small pulley where the a/c belt passes through. That is the idle pulley, the screw on the bracket of that idle is on the top side where you could adjust to loosen the tension of the belt. Before loosening it, loosen the bolt on the front of idle pulley.
Hope FixYa helps you out!

It only does this when its very cold outside, but my 1984 Volvo 240 is squealing very loudly when I accelerate? What would be causing this and how can I fix it?


Probably a slipping fan belt. Check the belt tension when it is very cold and see if one of the belts is loose. If so, loosen the bracket bolts to the alternator, power steering pump, or air pump (if equipped), and pry with a large wooden broom handle against the appropriate item until the belt is tight, then tighten the bolts.

I need a belt diagram for a 91 Geo Metro. I am replacing the alternator belt, but need to get the first belt off.I do not know where the belt tension adjustment bolt is for the first belt.


I believe the air conditioner belt tensioner bolt is underneath the mounting bracket on the compressor, then you can remove the alternator belt by loosening the two bolts from underneath on the alternator then loosen the top bolt and be careful prying the alternator inward to loosen the belt you can short a wire connection. Remove one of the battery cables to be safe!

I need to replace to replace fanbelt on 300D 1984 mercedes.


Transit Guru360 is right, It's not so hard and you might remove a few extra nuts...but once you've done it, it's a piece of cake the next time.

I just did this on my 300CD and this is what you do...

I dont have a AC belt since my AC doesn't work I removed it a while ago

1 You'll need:
a. a nice long pry bar (for tightening belts later)
b. a pair of 13m and 17mm wrenchs as well as sockets to do other side of each bolt.
c. a pan for the antifreeze to drip into since you'll remove the top hose to give you more room to
work and it will be full of antifreeze.
d. straight screwdriver
e. Some Gojo...yes working on diesels is a dirty dirty job

First take off top radiator hose, then smaller overflow hose, then upper and lower air intake hoses and unplug that little wire...not sure what it does, but it's in the way.

The power steering and alternator both have 3 bolts that hold them in place...you'll have to remove the power steering belt first. These are all 13mm. If standing at drivers side, there's a bold at bottom of powr steering pump, its an adjustment kind, remove the nut or just loosen it but leave bolt in.

Then remove the other two bolts, they are recessed in the back of pump on lower side. You can see which ones they are by looking for the nuts on front of pump. Loosen them and remove them.

Pump will be totally loose now, take off that belt and carefully finagle it around fan and off if need replaced, if not, just drop and let hang for now.

Then onto Alternator which will be bottom left of engine as you look at front of engine. Theres a through bolt on bottom of alternator, just roll up your sleevesand climb under car and use 17mm wrench...the alternator is threaded so there's not nut down there to loosen. Dont remove this bolt, just loosen it well.

Now loosen the top 2 bolts, dont worry about the adjustment, mine was stripped...and my adjustment was the prybar:) Loosen those but dont remove them...wiggle the alternator until it gives you the slack you need to remove the belt, if you cant get the slack, you can wrap your fingers around the belt upper and lower and squeeze, this will give lots of leverage and force alternator to move in, then pop that belt off and discard.

Now just put the alternator belt back on, use prybar to get proper tension...and tighten. A half inch of play is about the right tension...but tighter is good with a new belt since it will stratch a bit over time.

Make sure all 3 bolts are tight on alternator then move to replace power steering pump belt, but you will have to put at least onee of the top bolts back on to pivot against when using prybar to tighten that belt, then once you have the tension you want, tighten adjustment bolt, then keep the tension and put 3rd bolt in and tighten, make sure all are tight and you have 1/2 inch play on that belt as well. Then put all the other things back together ...check to make sure all tools are out from engine compartment and fire it up, if it squeels, it's too loose, if not, you're good and you can wipe down your tools, put them away and use the GoJo:)

Good Luck!

How to change the Compressor and Alternator belts? Corolla 1997


First, you will need a lot of money. A GM air conditioner compressor is very expensive.

I would only let a qualified mechanic make this replacement.

After all, the compressor costs about 800 to 1,000 dollars. i would only trust a mechanic to work on my cadillac
