| I do not think there is anything the matter with PII cooling system. Otherwise we should not have done so well with a smaller radiator & closed bonnet on PI. What I do think however is that our fan drive is entirely out of date and probably in service not 50% effective. Am. cars with latest-type rubber belts and solid adjustment are practically fool-proof in this respect. | ||
