PROBLEM. I have just replaced the original radiator on my 1967 TR4a engined Plus 4 DHC with a new aluminium one from Mulfab and my thick fan belt and pulleys with the newer thin version. There is insufficient room on the engine side for the old cooling fan and also no attachment points on the water pump pulley, so the obvious answer would seem to be a "Pusher" type electric fan in front of the radiator.

Has anyone done this, if so, what fan did you use and have you had any adverse effects?

Many thanks in advance


Suggest You look at installing a Honda thin fan with shroud on the inside of Your radiator. You do this by extending the rad perches and moving the rad forward. Contact Me offline and I will send You information. wmbutton@gmail.com BTW: this is a U.S. product called "Flex O Lite".


Sorry I failed to answer Your second question. Yes I use a SPAL fan in front of My +8 Radiator. It works OK at slow speed (In traffic) but at 70 MPH pulling a long hill My +8 heats up. I must slow down to about 50 MPH to cure this. My theory is the Spal Fan in front acts like a air blocker at speed.

Is the area under the radiator blocked off? It's said that otherwise air pressure can build up in the engine compartment restricting air flow through the radiator.


NO! But it has been in the past and blocking under the rad is a good idea. Read Dwight Smith article on GOMOG.
