Dave,
Are you REALLY that stupid ? Let me clarify as you obviously do not understand. On the Escort Cosworth it has two fans, only ONE comes in on the first stage THIS IS NOT MAN ENOUGH TO KEEP TEMPS DOWN . THE SECOND STAGE DOESN'T COME IN UNTIL 100°C - are you with me?

If you fit the Sapphire fan switch BOTH FANS COME IN TOGETHER - WHICH IS MAN ENOUGH TO BRING TEMPS DOWN.

Please tell me you have now grasped this?

YOU REALLY ARE A MONGALOID TWAT .
