Hello
Kenlowe recommend a 13" blower fan i.e. one which sits in front of the radiator. They call it a 13.B.
However Mitch and I feel this is not the best place for it. There's not a huge amount of room in there and it does restrict natural air flow to the radiator when the fan is not working. It's also restrictive for maintenance if the fan ever needs it.
So, me and Mitch are going for a sucker fan that fits on the back of the radiator and sucks air through the radiator. We've gone for a 12" curved blade one (off Ebay!) that shifts more air than the Kenlowe 13" one (1170CFM at zero resistance). There are plenty of fans available in the aftermarket from companies like Spal and Pacet. Switches you can get from your local motor factor, or somewhere like

Most modern fans now fit through the cores using some glorified cable tie things so they are fairly easy to fit as long as you have measured up correctly.
Unless you are very nervous about overheating and/or electrical failure your old plastic fan needs to come off - I think it's 6 bolts into the water pump pulley.
Can't think of much else.
If you are going to stick with Kenlowe, they are very helpful and you can deal with them direct at

Good luck!
