Fri, 09 April 2004 13:56 After you raise the back of the bonnet or remove the rubber bonnet seal, check where the air is flowing while you are driving by doing some wool tuft analysis. Just sticky tape a piece of light wool onto the trailing edge of the bonnet. If it flies up - looks like air is coming out from under the bonnet. If it gets sucked into the engine bay, air is likely to be going in. The area at the base of the windscreen is a high pressure area and at speed air may go INTO the engine bay. This may sound OK, but it may also reduce the airflow into your engine bay through the radiator / intercooler. I'm sure bug companies like Toyota would have not put in that bit of bonnet rubber sealing if it didn't do anything (they could save a few bucks). I took it off anyway, because it does reduce underbonnet temps when the car is going slowly / in traffic (checked with underbonnet thermocouple over the turbo). [Report message to a moderator]
