Title: Stuck belt tensioner
Post by ottopmh on Oct 12^th, 2006, 11:14am

Hi,

Tried to change the belt to my 2,3 (with A/C). The tensioner seems to be stuck badly. Tried using quite much force, but nothing happened. Didn't dare to use more...

I sprayed some lubricant to it (to the hole from which the spring can be seen) yesterday, but haven't tried again yet.

Any good advices how to make it loose?

Otto

Not familiar with the 2.3 let alone A/C but the tensioner is quite hard to move. With a socket on the nut in the middle of the pulley and a ratchet or bar pointing away from the tesioner pivot point you still have to push down on the bar/ratchet fairly hard. If it still doesn't budge I can only sugest cutting the belt, watch out for the tensioner springing up. If the tensioner still doesn't move then it's seized. You may be able to free it up but plan on replacing it with another (2nd hand?) tensioner.
Good luck!
Graham

Have you tried pulling the tensioner downwards from underneath the vehicle..... you can use more of your body weight that way ;)

As the tensioner is below the thermostat housing I suspect leaked coolant may have contributed to the seizing up of the spring in the pulley arm.

I would cut the belt and try to free the arm up with plenty of WD40 ( a good smack with hefty hammer may be needed ).

Same problem last year.

Squirted normal oil where you can see the spring followed by half a can of WD....
Next morning quick sharp yank ...no problem... ;D
Just surroud lower part with an old rag for the run off..

Good luck

does the 2 litre have a belt or a chain?

It has a chain for timing but this thread is on about the belt and tensioner for the alternator/water pump etc.

Further to all points above, having just changed alternator on my 2.9 12v - thought tensioner was going to be a pain but found 2 ft pipe (part of trolley jack handle) on the socket wrench (turned clockwise) made moving the tensioner effortless, down to release the belt, and later to replace belt. There was no way I could have moved it without the extension - also valued my knuckles! (Tip given in helpful instructions on site at: http://www.fordscorpio.co.uk/alternatorer.htm)

Cheers, johndyork.
