hi guys, i have fitted a electric fan to the rad, and wondered if i should fit a shoud cover over the rad, as well. most modern cars have them. i believe to push the air thro, the fan. what do you thing , paul

Your fan or fans should cover as much of the radiator as possible

By doing this you should not need shrouds

Cooling efficiency is related more to volume of air that the fan puts through the radiator

Rule of thumb is that a radiator will need approx 1/3 of rad size opening in front and about 2/3 clear behind it
