I own a Ford Orion Mk1 with an RS Turbo S2. It has some modifications like Kent cam, Simota air cleaner, custom built 4-pot intercooler, Garrett T3 and a superchip, which result in a best recorded 1/4 mile time of 13.6s. However I have a problem with the engine temperature. The car used to have two fans but one of them had to be removed becuase the intercooler took its place and stands in a vertical position. Since then, when I get stuck in traffic, temperatures go up exactly below the red mark. If I switch off the engine when the temperature is this high some coolant water is released from below. I'm sure it's not a blown gasket, and when I'm driving at cruising speed the temperature goes down. I know that in my country temperatures are very hot in summer but I don't think this is normal. I've fitted Bailey's oil breather and swirl pot to help a bit and I'm planning for a fifth injector and water injection. But still, what could be the possible cause of this?
