Hi, I have got a small leak on the expansion tank on my Fiesta. Does anyone know if there is somekind of sealer you can put in the tank to seal the leak, or will I have to buy another tank?
Regards Dave
Use a new or second hand tank, Dave - any sort of sealant will give you grief at the end of the day.
If the coolant runs out, the cylinder head gasket pops - thats the last thing you need!
