Stagecoach MCSL - Chester & Wirral Depots

[PO59 MXJ]

RE: Stagecoach Chester & Wirral
There is a commom fault with them B7s that First and Stagecoach tried and could not fix. The saloon heating is in the roof and when the bus is turned off of a night, the coolant drains down and comes out of the overflow, rather than going back into the coolant tank. Once they're on the road for an hour and the coolant is back in the heating system, the tank is then near enough empty and warning lights start appearing. 21260 and 21275 were the worst for this.
