2006 LAND ROVER FRELANDER 2 spark plugs

ItemPart NumberDescription1-Seal2-Coolant pumpThe coolant pump is ins t alled on t he RH side of t he cylinder block rear face and is s ecured and s ealed via 6 bolt s and an 'O' ring.The coolant pump and power s t eering pump are bot h driven by a single pulley via a poly-vee belt . A keyed s haft at the front of t hepulley drives t he power s teering pump, while a driver mechanism at t ached to t he rear of t he pulley drives the coolant pump.
Coolant Inlet Pipe

Variable Camshaft Timing Solenoid and Camshaft Position Sensors
ItemPart NumberDescription1-CMP Sens or - exhaus t cams haft2-VCT s olenoid3-CMP Sens or - intake camshaftThe profile, or pos ition and shape of the cams haft lobes are opt imiz ed for a cert ain engine rpm, but this normally limit s low-endtorque or high-end power. At high engine s peeds , an engine requires large amounts of air. However, t he intake valves may clos ebefore all t he air has been given a chance t o flow in. On t he other hand, if the cams haft keeps t he valves open for longer periodsof time, problems st art t o occur at t he lower engine speeds . This will caus e unburnt fuel t o exit t he engine s ince t he valves arest ill open.
To overcome t his , VCT changes t he valve t iming by eit her advancing or ret arding the cams haft s t o allow for opt imum engineperformance, reduced emis s ions, and increased fuel efficiency. This is achieved via an electronically controlled hydraulic s olenoidvalve locat ed in t he camshaft housing at t he rear of t he engine, behind the rear CPS s olenoid. The ECM t rans mit s a signal t o thesolenoid, which direct s engine oil int o t he VCT unit. A valve s pool in the VCT unit regulat es t he flow of oil.For addit ional information, refer t o: Elect ronic Engine Cont rols (303-14A Elect ronic Engine Controls - I6 3.2L Pet rol, Des cript ion andOperation)..
There are 2 CMP s ens ors locat ed in t he camshaft housing. The CMP s ensors monitor the posit ion of the cams haft s t o est ablis hignit ion t iming order, fuel injection t riggering and for accurate VCT cams haft advance-retard t iming feedback.
The CMP sensor is a Hall-effect s ens or, which s wit ches a batt ery fed supply on and off. The s upply is s wit ched when t he t eet h ofthe reluct or pas s by t he tip of t he sens or. The 4 t eet h are of differing s hapes , s o the ECM can determine t he exact pos it ion of t hecams haft at any t ime.For addit ional information, refer t o: Elect ronic Engine Cont rols (303-14A Elect ronic Engine Controls - I6 3.2L Pet rol, Des cript ion andOperation).

Driving hints
R
ECONOMICAL DRIVING
There are two main factors which influence fuel
economy, the way the vehicle is driven, and
maintenance.
Driving tips for economy
• Avoid unnecessary jour neys, especially
short stop-start trips.
• Accelerate smoothly and gently from a
stand still.
• Use the gears to avoid labouring, or
over-revving the engine.
• Allow time to brake gently and smoothly.
• Be aware of traffic and road conditions
ahead, and take action in time to avoid
hard braking or acceleration.
• When stationary apply the park brake, and
select neutral.
• Turn off the air conditioning when not
needed.
Maintenance and fuel economy
Regular servicing by a Land Rover
Dealer/Approved repairer, along with regular
checks by the driver are essential for vehicle
longevity and fuel economy.
The condition of the engine (oils, filters, spark
plugs, settings etc) tyre pressures, and wheel
alignment, will all have a bearing on fuel
economy. For this reason it is essential that the
vehicle is checked regularly by the driver, and
serviced by an approved Land Rover
Dealer/Authorised Repairer at the correct
intervals.
Note: If you are in any doubt about the
maintenance requirement s, intervals, or
checks required, contact your Land Rover
Dealer/Authorised repairer for advice.
