WARNING

Hot liquid under pressure!
Never remove the filler cap or the recovery tank cap while the engine is running or the coolant is hot.
Let the system cool. Turn the filler cap to the first notch and allow any pressure to escape, and then
remove the filler cap. Loosen the recovery tank cap slowly to allow any pressure to escape.
Failure to comply could result in death or serious injury.

W0296A

NOTE:

emissions sensors mounted in the exhaust stream are sensitive to extreme vibrations. Use of tools that gen-

erate extreme vibrations, such as impact wrenches and hammers, will result in damage to emission sensors. Avoid
using these tools during any service procedure in close proximity of emission sensors. If the use of these tools cannot
be avoided, remove the sensors using extreme caution prior to performing any service procedure.
