I- -1 n21 2 MOPAR PERFORMANCE PARTSOIL COOLERSEngine Oil CoolerThis specially engineered, finned radiator design oil coolerprevents engine oil from overheating, thus ruining itslubricating characteristics. This cooler is ideally suited forendurance-type engine applications and utilizes 1/2" pipethread fittings. Measures 1 1 " x 12" x 1 - 1/2".P3690956Engine oil cooler.Heavy Duty Engine Oil CoolerThis heavy duty steel, full flow oil cooler is the best wayto ensure peak engine oil cooling efficiency under heavierthan normal driving conditions. It is thermostaticallycontrolled to provide continuous cooling of your engine'soil. Install in oil filter circuit. Oil circulates in acontinuous loop from the pan, through the pump, then tothe cooler. Includes built-in relief valve. Designed forsimple installation. Cooler is 1-1/2" thick. Measures 6" Wx 18" L.P48769 17Heavy duty oil cooler.Universal Oil Cooler PackagesSpecial universal coolers mount between engine and oilfilter to circulate heater core coolant to reduce oiltemperatures.P4529690P452969 1OILUniversal oil cooler package, standard.Universal oil cooler package, extra cooling.Use only high detergent and additive engine oil. The oilmust meet Mil Spec MS-DG. DO NOT use viscosityimprover oil additives. The only oil additives you shouldconsider using are anti-scuff additives, such as MoparEngine Oil Supplement. Anti-scuff additives should beused only for running in and should be drained from theoiling system before racing (be sure to re-fill the engine oilto the correct level before re-starting the engine).SAE ViscosityAn SAE viscosity grade is used to specify the viscosity ofengine oil. Use only engine oils with multiple viscositysuch as 5W-30 or IOW-30. These are specified with a dualSAE viscosity grade which indicates the cold-to-hottemperature viscosity range. Select an engine oil that is bestsuited to your particular temperature range and variation(Figure 4-38).Il iENGINE OIL VISCOSITY GRADES-29" -18" -12" -7" 0" 16" 27" 38" 1Temperature range anticipated before next oil changeOil Level InspectionFigure 4 - 38Caution: DO NOT overfill crankcase with engine oil,pressure loss or oil foaming can result.Inspect engine oil level approximately every 800kilometers (500 miles). Unless the engine has exhibited lossof oil pressure, run the engine for about five minutes beforechecking oil level. Checking engine oil level on a coldengine is not accurate.To ensure proper lubrication of an engine, the engine oilmust be maintained at an acceptable level. The acceptablelevels are indicated between the ADD and SAFE marks onthe engine oil dipstick.1.2.Position vehicle on level surface.With engine OFF, allow approximately ten minutes foroil to settle to bottom of crankcase, remove engine oildipstick.3. Wipe dipstick clean.4.5.6.Install dipstick and verify it is seated in the tube.Kemove dipstick, with handle held above the tip, takeoil level reading.Add oil only if level is below the ADD mark ondipstick.Engine Oil ChangeChange engine oil at mileage and time intervals described inMaintenance Schedules of your owners or service manual.Run engine until achieving normal operating temperature.1. Position the vehicle on a level surface and turnengine off.2.Hoist and support vehicle on safety stands.3. Remove oil fill cap.4. Place a suitable drain pan under crankcase drain.II
