VW Overheating
 

My 1985 Passat runs too hot. It's been getting progressively worse over the
last five years. It's not the rad or the theremostat. I think it's the
corrosion in the water galleries getting slowly worse restricting the flow.
Is there a solution to this other than a new engine? Any help would be
appreciated. Thanks

Corrosion or scale buildup? Sure it's not the water pump or fan clutch?
Water pump impellers can wear off over time.

You know this because ...

Remember, just because you can see water in your radiator, doesn't
mean it's plugged. A new radiator is cheap compared to the
replacement of a head or motor and, since you're driving an 85, it's
entirely possible that's all it is.

Things that can also cause what you describe:

Water Pump
Fan Clutch
Bad Timing
Head Gasket going bad.
Transmission overheating (if you've got an auto tranny)

You won't have "corrosion in the water galleries" if you have used the
proper coolant mix through the life of the vehicle. How do you know it's
not the rad or the thermostat? How do you know that you don't have a bad
temperature gauge? When was the last time you changed your accessory drive
belts, cleaned your radiator or looked for rat nests under the hood?

To answer your question, there are coolant flush kits, and businesses who
perform this service for their clients. I assume that they will be
available in the UK. Follow the directions exactly. If your problem is
clogged water galleries, it may help.

Cheers,

Earle
