I=E2=80=99m not sure it reduced heat, but it looks great!

didn't notice any difference in running temps.

In 1991 bolt on cooling fans didn't have sufficient CFMs to be =
particularly effective, but worked well on the jags and MGs that had =
them simply because they designed the systems around the CFMs they could =

viable option now.

Although my view still remains to make sure the cooling system is =
sorted, suggest jet hot coating the exhaust header first, and go with a =
plastic 5 blade fan and use a 165 deg thermostat. If that still doesn't =
work then consider adding a fan.

Always fit a thermo-switch and a manual override switch. The thermo =
switch should be compatible with the opening temperature of the engine =
thermostat. The thermoswitch should switch off at a temperature about 5 =
degrees C over the opening temperature of the thermostat. It should =
switch on near 90-95 degrees C.
Remember, the higher the temperature the better the cooling because of =
an increase in Delta T.
