Cooling fan

[malc4d]

My '73 US car with A/c seems to have a cooling fan with fewer but wider blades. Is this normal and as Triumph put a fan with more blades later should l exchange it ?

I think you'll need a conversion kit to change it. Different viscous coupling & pulley. Probably will provide more cooling.

My car only had twin 10" electric fans mounted in front of the radiator, when I retrofitted aircon to my car I chose the EJ Ward ally rad to which we welded brackets to mount the condenser. I then fitted a 16" Davies Craig in front of the condenser, the fan only runs if the A/C is on or the engine needs some cooling. I was advised to use a modern high flow condenser mounted as described rather than the original set up. I have also used a more efficient axial compressor instead of the original reciprocating York type. The A/C unit supplies air at 3C even on a tropical 35C day.

Sorry cant help you with the support bracket, it would be easy enough to fabricate from thin walled mild steel tube with the ends flattened and drilled for the bolts.
hope the above is of some use,

Not sure if Malc is referring to the A/C condenser fans or the rad cooling fan which was different on the early cars... as were the A/C fans for that matter.
Mine look like this.

Your picture just answered the question Nik....It seems that your plastic fan looks like mine, less but wider blades. It doesn't show up in the parts book though...If you look at the fan available it has more but thinner blades. Hmmm, does this mean that the newer cools better. Anyone ?
Raoul, where did you get the ' modern high flow condenser '...do you know which car ? and do you have the part no. for the compressor ?
