Stock M Series Cooling Fans
The early M series used two electric cooling fans in the States and one fan in the UK.
The fans were white, had six blades, and were made by Kenlowe Accessories, pn: KLM 1005.
The UK cars switched to a black ten bladed Kenlowe
fan, which pushed much more air than the white ones.
Replacing the six blade fans with
ten blade units puts much more air through the radiator without having to modify
the car to use different electric fans.

The late MGB used two yellow four bladed
fans, I have used them too, but they don't fit too well and the black Kenlow fans push more
air and vibrate less.

M Series Radiator Mounting
The M series cars used two styles of radiator: the "large" radiator, used on most Taimar
and 3000S which mounted behind the spare tyre and the "small" radiator used on all other Ms
and all the Turbos which fit under the spare tyre. ("Large" and "small" seem to be factory
terms.) The "small" radiator is mounted with two pins on the bottom which fit into holes on
the frame and a bracket on top with a bolt hole that matches a bracket on an upper frame tube.
Most people clamp these brackets together as the factory intended. When driving through pot holes
(a rarity in England) the frame flexes from side to side - the very stiff radiator, pinned
between the two pins and the bracket resists this flexing and sometimes snaps a solder joint.
Throw the bolt away to prevent this problem. Between the pins and hoses
the radiator isn't going anywhere.
