I am in the process of installing an aftermarket electrical cooling fan. This basically involves wiring up the fan that will sit in front of the radiator. Once this is installed and running, I will remove the belt driven fan.
Why?
Because: the belt fan draws constant HP. It runs whether I need it or not. For example, you don't need a cooling fan at 50mph. It also runs when I don't want the engine to be cooled - for example, when I start the car in the morning and its cold. The cooling fan is also quite noisy.
The later Bs came with twin electrical fans as standard, but my car had it removed at some point, so I am basically returning it to its earlier state.
OK - the point of the post...Be very careful installing the fan - they come with plastic wires that are supposed to be threaded through the radiator. I did this and punctured the radiator - DISASTER. So now I either get a new rad, or get this one fixed. A better solution is to build a mounting bracket for the fan. I'll post more details on my solution later.
Apparently, from others on MGExp forum, this is not a unique problem - other folks have inadvertently damaged their radiators installing these fans. So you have been warned.
