Ford Galaxy / Ford S-MAX. Manual — part 258

NOTE: The varying design of compression checking devices and fluctuating starter motor
speeds normally only allows for a comparison to be made of the compression pressures in
all cylinders.

1. 1. Using datalogger in the

Ford diagnostic equipment

, check that the fuel pressure

has dropped to zero and that the fuel temperature has either reached ambient
temperature or is below 30°C, whichever is the greater.

2. 2. Raise and support the vehicle. REFER to:

Lifting

(100-02 Jacking and Lifting,

Description and Operation).

3. 3. Remove the engine undershield.
