Try spraying silicone spray on the belt, if you haven't got that then flash dash type stuff is the same, just with fragrance.

If you have belt squeal, then that implies slippage.
In my opinion silicone spray is a lubricant, so great on bearings, but a big no no for a slipping belt.

Personally I would use Belt Dressing such as by Rocol.
It is made for that exact purpose.

If the belt is slipping already, before the car gets properly "winter cold", then I think even belt dressing would not be enough.

My understanding was that belt dressing was basically a silicone spray, perhaps I was wrong but have used it for years. Also when I've had a slipping belt I've also roughened the surfaces of the pulleys with emery paper to improve the grip.

From the Rocol website...

ROCOL BELT DRESSING Spray has metal detectable plastic components (aerosol caps and actuators) capable of detection by most metal detection equipment. Excellent temperature resistance -50°C to +100°C.

BELT DRESSING Spray extends belt life and transmission efficiency by conditioning belts to prevent drying out, cracking and ultimately breakage.
Thin adhesive film increases adhesion when the belts are in contact with drive pulleys, reducing belt slippage which causes glazing, overheating and drying out.

BELT DRESSING Spray is equally effective in damp or wet environments as in dry and clean conditions due to its insolubility in water. Blue spray nozzle for easy identification as a foodsafe product.

And from Google -

LPS Belt Dressing is an industrial product designed to reduce slippage and extend the life of rubber belting.

It contains isohexane and a mixture of propane and isobutane which are very flammable, and if handled improperly can be dangerous.

Cheers, I'll see if I can get it to tension a bit better, the mk1 yaris has a pretty poor belt tension system sadly, basically lever and tighten.
New alternator, new belt so it's not getting any new parts. I might see if I can retrofit the mk2 tensioner onto the mk1 as that's adjustable. Shall see. If that belt stuff is what you use that'll be good to have on the shelf too I suspect

Another years MOT on the wee beast, though she is starting to show signs of degrading, sills will need repairing within the next 12 months. and whilst fitting the rear view camera - I noticed that the rear arch tubs are showing signs of corrosion where the panels meet (and I have a leak into the boot somewhere...)

Otherwise, its running well in 8 years of ownership now.

I suppose for 22 years old a bit of welding on the horizon isn't too bad. Its always great to get another years ticket on your car.

[Robsey]

I am not totally surprised about the corrosion.

Claire the original owner had become a very poor driver, especially with regard to spatial awareness on her left side. Hence all the battle scars when you took ownership in 2016.

I recall a rear bumper spacer not locating properly, indicating potential panel damage on the rear left corner.

But then it still sounds very solid for a 22 year old car.
My cavalier was a pile of rust holes underneath at 20 years old.

Congrats to the pocket rocket for the MOT pass.
Happy days.

Aye, it needs some fettling, see how I feel about it next year.
