What a super looking van! A credit to the previous owners, so look after it! I notice the number plate is right over the ducting that scoops air into the rad, so if things get a bit "warm" check this out first.
Hi MattMonkey
i had the heater problem so ifitted a water cutoff heater valve fom a Rover 100 under the dash and a old choke cable to pull it off and on works a treat.
