We have discussed cooling ad nauseum on these pages, Tigers United, club pages
and in shop notes and newsletters everywhere. The solutions are usually better
water pumps, better radiators, blocking the horn holes and under the rad,
auxilliary fans etc., all items associated with the water cooling system.
Here are some other ideas that come to mind that may or may not have been
discussed before.
My car has the rectangular bodywork opening in front of the radiator cut down
at the bottom by about 1" so that little of the radiator face is blocked - a
looks like a crude 1960's mod. or is that stock Tiger?
Oil cools the engine too, so a windage tray and a larger (7 Qt) oil pan with
cooling fins would help too.
Those of you with interest in the works rally cars may have Marcus Chambers'
book "Works Wonders", and the wonderful new Graham Rood book "The Works
Tigers". In both of those books Des O'Dell is quoted as fixing the Tiger
cooling problems by "taking a pipe from the header tank to the bottom hose"
similar to Aston Martin and Mercedes. Has anyone tried this?
The other obvious item you can see from the works cars are the holes in the
side of the fenders to exhaust hot air from the engine bay and encourage
proper flow through the radiator. Not many of us want to do this, so less well
known was the practice of propping the hood open a little at the rear. They
did this by adding some hard foam blocks in front of the driver and co-driver
at the rear of the hood land with gaps at the center and at the edges. I
suspect this was to avoid spraying the windshield with oil and coolant. They
used external latches to hold it down but hood pins would work or perhaps even
a longer "stock" bonnet latch pin for those averse to cutting holes.
