This page covers tipping the engine to gain access to the pulleys and full lowering of the engine. Tipping The Engine As with other smarts, the access to the pulleys is restricted but tipping the 451 engine is a bit more tricky. Place a jack under the gearbox and...

Premium Mod 45bhp CDI EGR Clean451 Fortwo

Diesels are dirty engines, they are noisy but they are efficient. However, if they can't breathe then you aren't getting the best from the engine.

Draining Unless you like to be scalded, wait until the car is cold. Remove the front service panel and undo the cap to the coolant header tank. Look under the car at the engine over to the right. Just behind the long drive shaft, partially hidden by some...
