I have an annoying problem on my 1985 Thunderbird.
I just replaced the power steering pump and tension pulley and now the belts squeak very loudly. It is quiet at idle, but gets very loud when driving or revving the engine.
It seems to be emanating form the lower pulley (the one connected to the crank shaft).
As a side not the harmonic balance was replaced recently and it still has a slight vibration at about 1,000-1,500 RPM's. Not sure if this is related or not.
I used belt dressing and even soap (an old mechanics remedy) it seems to be fine for a while but after letting sit for a while and re-staring it the squeak is back.
I tightened the belt and it still squeaks.
Any suggestions?
Thanks all,
Mark
