Start with the basics. Which model 98 (tip/5spd)? mileage? Recent service history? Was anything changed recently that was followed shortly by the screeching sound? Motor oil fresh with good color? Power steering fluid clean and topped off? The polyrib belt should be changed at 60k and 120k miles. Was this done?

You can remove the carpet and access panel behind the seats to get to the belt and pulleys. Give em a look. Release the belt tension and give each of the pulleys and accessories a spin. If one has a failed bearing you will know.

It's a 5spd manual. 81,000 miles. It had a service about 14 months ago when the mileage was at 74,000 miles.

Just one question is it east to see what is wrong - ie which belt will need changing? Could it be a different belt that is worn?

The screeching started after a very slow four hour journey. Stuck in a traffic jam outside London for at least two hours. i kept hearing the fan coming on to cool the engine.

First, stop driving the car. You only have one serpentine belt that turns everything; if it goes bad because of an idler pulley, or the water pump, you risk killing the engine due to overheating. The belt is a snap to change, but you need to find out why it suddenly failed. If you are not mechanically inclined, have it flat bedded to someone that is.................
