Checking and adjusting the valve clearance must be done on a cold engine (coolant temperature 20˚С), with the cylinder head mounted on the block
To prevent damage to the cylinder head, wait until the engine has cooled down before removing it
Checking the technical condition of timing parts
Sprockets, hydraulic tensioner, chain guide and tensioner arm
Checking the technical condition of the timing drive
Remove the top cover.
Check the timing belt (A) for damage, oil or coolant ingress
By default, we already have the cylinder head removed
Power units are designed for operation at ambient temperatures from minus 60ºС to plus 50ºС, relative humidity up to 98% at a temperature of 25ºС, air dust content up to 0.4 g / m 3, as well as for movement car in mountainous conditions at an altitude of up to 4500 m above sea level and overcoming passes up to 4650 m above sea level with a corresponding decrease in power and economic indicators.
Thermal gaps in the valve mechanism are used to ensure a hermetic fit of the valve on the seat, when the parts of the valve drive expand during engine operation
