WARNING:

Risk of scalding due to hot steam and hot coolant.

  • The coolant system is under pressure when the engine is warm.
  • Cover the coolant reservoir cap with a cloth and then open it slowly to release the pressure.

Danger of personal injury due to the coolant fan turning on by itself.

  • The coolant fan can come on even when the ignition is turned off, for example, caused by the heat still in the engine compartment.
NOTE:

Secure all hose connections with hose clamps of the same type as those equipped by the factory. .

Arrows on coolant pipes and coolant hoses must line up across from each other.
