Jeep Grand Cherokee
With the engine off, spray a liberal amount of cleaner onto all metallic parts in the air opening. Let it sit for a few minutes, then crank the truck up and run it for several minutes. Shut the truck off and repeat the procedure until the metal is shiny and clean.4.
1. Alter the Glimmer plugs with higher-performance models by turning Everyone one in a counter-clockwise trail and securing a current one into the opening. Two matters affair the most on a Glimmer plug: heat radius and the fracture distance of the gratuity. The Grand Cherokee can employ a plug with a heat reach of four, on the other hand using a hotter or colder plug can interchange the performance of the Engine. For towing, or high-torque applications, a hotter plug Testament functioning bad. For highway driving, a colder plug gamut of three Testament be enhanced efficient. Be confident to "cavity" the plug, whether using a one-node dummy, to approximately .060 mm. Provided using multi-node, or all the more quad-tipped plugs, then gapping is not essential.
2. Install a Disinfected air filter by opening the air box in the front of the engine and replacing the bleached paper Component inside. A cleaner air filter can accrual the air flow to the Engine and hope for less petrol to burn. An aftermarket air snorkel instruments can maximize this air flow, on the other hand can author issues with the pc systems that manipulate an MAF sensor.
3. Clean the fuel injectors, intake manifold and throttle plate with a commercial spray cleaner. Take the air hose off of the intake manifold by turning the hand-screw on the unit in a counter-clockwise direction.A Jeep Grand Cherokee can bend between 12 and 20 miles per gallon, depending on the engine extent, options and weight of the Motor lorry. Increasing this mpg can be done by using additives, installing bolt-on Accoutrement and replacing perpetuation items with high-performance alternatives. The standard backyard mechanic can accretion the mpg in a Grand Cherokee in approximately two hours.
Instructions
Clean the MAF or MAP sensor, if equipped, by removing the sensor from the air hose near the air filter box. Most types are an in-line hose unit that will couple with the air hose with a hose clamp. Turning this hose clamp counter-clockwise will release the hose and MAF sensor unit. Some later models of 4.0-liter straight-six cylinder engines and most 5.7-liter V-8 motors will have a MAF or MAP sensor that meters fuel by constantly testing the incoming air oxygen content. These sensitive sensors can be cleaned with special cleaning spray that does not leave residue. Spray the sensor until it is clean, but do not touch it. Replace it and secure the air hoses.
5. Add BG-44K to the gasoline tank during a fill-up. This unique cleaner will break up carbon deposits in places the spray cannot reach. It will also clean parts of the fuel system chemically.
