I only have the electrical fan behind the radiator. There is no mechanical fan fitted to my car. The car came from New Zealand so maybe the mod was done there. If the electrical fan doesn't supply enough air to the motor for cooling then I would have expected this to have happened a long time ago. I will check the electrics this week to see if it is just a fuse or the harness or some other electrical component. Can a mechanical fan be refitted to the car? There seems to be a lot of space between the motor and the electrical fan and on the main drive shaft there is a one inch or so thread protruding forward. I suspect this is where the fan clutch would have been. The diagrams shows the fan that is non-existent on my car. Thanks for the help. Hear from you soon.
By the way where are you in Canada? It's a great place.
