Repair Sharan/Sharan Volkswagen>> System of greasing of the engine>> Oil radiator
At operation of the engine the temperature of karterny oil should not raise strongly in order to avoid falling of its viscosity. Partial cooling of oil occurs in the pallet of a case and in the filter case owing to обдува their air from the fan of system of cooling. To more intensive cooling of karterny oil apply oil radiators.
Because of the different device of oil filters on VR6 engines and 2,0 l are used various oil radiators.
Engine of 2,0 l
On the 2,0-liter engine an oil radiator 4 (fig. 177) is located between the basis 2 oil filters and the oil filter 6. The oil radiator acts in film only after removal of the oil filter and a detachment of hoses. For this purpose unscrew a nut 5 from the bottom surface of an oil radiator. Between an oil radiator and the basis the sealing ring 3 is established. At assembly a nut it is necessary to tighten the moment of 25 N · m.
On the VR6 engine the oil radiator of liquid cooling is established on lateral face of the block of cylinders (fig. 178) .
At liquid cooling the oil radiator consists in the case through which there passes working liquid of system of cooling of the engine, and decrease in temperature of engine oil is carried out by cooling liquid. Hoses for a supply and removal of cooling liquid approach to accession places on the filter.
To remove the oil filter it is possible after cooling liquid from system of cooling will be merged and hoses of a supply of cooling liquid are disconnected. Then unscrew a cover from outer side of the oil filter and remove a radiator. On each party of an oil radiator there is an O-shaped sealing ring which should be changed always if the oil radiator was removed.
The oil radiator with liquid cooling provides not only oil cooling at work under trying conditions, but also fast warming up of oil at engine start-up.
At installation of an oil radiator grease both sealing rings with engine oil. Establish a radiator and tighten a cover the moment of 25 N · m. Attach hoses and fill in cooling liquid in cooling system.
