Mazda 6. Manual - part 13

LUBRICATION SYSTEM 

.

•

A silent chain (link connecting type) has been adopted to the oil pump chain to reduce chain operation noise 
when the chain and the sprocket engage.

•

The engine oil in the engine front cover lubricates the oil pump chain. The wear resistance has been improved 
by the nitriding processing of the pin constructing the oil pump chain.

•

The durability has been improved by heating the sintering material on the oil pump sprocket inside of a furnace.

OIL PAN

A6E333010040T01

Structure

•

An aluminum alloy oil pan has been adopted for weight reduction. A silicon sealant with excellent sealing 
qualities has been also adopted.

•

Oil pan baffle plates have been adopted inside the oil pan to stabilize engine oil diffusion by crankshaft rotation 
and oil level when the vehicle rolls.

Structure

•

A plastic oil strainer with a resin filter in the middle of the strainer has been adopted for weight reduction.

OIL FILTER

A6E333014300T01

Structure

•

The oil filter is attached to the right side of the oil level gage (oil pan side) on cylinder block.

•

The oil filter adapter has been adopted for weight reduction. The oil pressure switch is installed on the oil filter 
adapter.

•

A resin oil filter has been adopted for weight reduction. A drain has been installed on the bottom of the oil filter 
replacement service ability.

•

An environment-friendly oil filter, designed so that only the internal oil filter (rather than entire assembly) need 
to be replaced, has been adopted. The replaceable oil filter is made of a material that can be completely 
incinerated.

•

A water-cooled oil cooler has been adopted to reduce the engine oil degradation. Also, the exclusive use oil 
filter adapter has been adapted for the oil cooler. (LF and L3 engine models)
