engine coolant LAND ROVER FRELANDER 2 2006 User Guide

To ensure t hat the air is releas ed from t he oil sys tem, a valve is locat ed in t he oil pump on t he pres sure s ide. During t he build-upof press ure, air is routed out into the crankcas e. This cont inues unt il t he valve clos es at approximat ely 0.2 bar.
Oil Filter and Cooler Assembly
The majorit y of oil is routed t o the oil filter, which is a s eparat e s ingle filt er element locat ed in t he housing. The over-flow valvefor t he blocked filt er is in t he cover. The valve opens at approximat ely 2 bar.
There is a valve at t he bot t om of t he hous ing. The t ask of t he valve is t o drain t he housing of oil when t he oil filter is removed.W hen the oil filter is ins t alled, the valve is closed. A spring loaded ring at the bott om of t he filt er hous ing is affect ed by t heact ual filt er. The ring is , in t urn, mechanically connected t o the valve.
W hen the filter is removed, the s pring lifts the ring, which, in turn, opens t he valve whereupon t he oil drains to t he oil pan.

The non-return valve ens ures that t he oil filt erhous ing is not drained of oil when the engine is s wit ched off. The valve opens at approximat ely 0.2 bar.
The oil first pas ses t he oil cooler, a plat e oil cooler. The chamber for oil and coolant is split alternat ely between the plat es. Thereare 20 plat es used in tot al. The first 16 plat es are us ed for oil, which is routed through the engine's normal lubricat ion circuit , i.e.the oil is routed t o t he oil filt er.
The 4 las t plat es are us ed t o provide a proport ion of the oil with ext ra cooling before it is rout ed onwards to cool t he vibrat iondamper. The circuit is calibrat ed t o achieve correct flow.
There is a by-pas s valve parallel t o t he oil cooler. The valve ens ures an oil flow to t he oil filt er even if the oil cooler is blocked.The valve opens at approximat ely 2 bar.
Intake Valve (Piston Cooling)
The oil is also rout ed to the duct for oil cooling, which is parallel to t he ducts for main bearings and connect ing rod bearings .
The oil first pas ses a valve that opens/clos es at approximately 2.0 bar. Thereaft er, t he oil is rout ed to the jet s for pis t on cooling:
If the valve has t oo high an opening pres s ure, t his means that t he oil flow t o t he pis t ons reduces , which can caus e enginedamageIf the valve has t oo low an opening press ure, this produces an increas ed flow t o piston cooling. It can, in certain s ituat ions(before the relief valve is opened) result in t he engine's oil pres s ure being t oo low causing engine damage
The jets direct the oil t owards the underneath of t he pis tons. Each cylinder has it s own jet .
