How to Prime the Jeep Oil Pump
Priming the oil pump in your Jeep engine brings the oil pressure up to normal before the engine is started.
This will protect the engine from premature failure cause by a dry start. Dry start is a condition whereby
the engine is initially run for a short time
without any lubrication on the bearings
. This can wipe and spin
bearings and cause quick and devastating damage to the engine internals. Priming the engine using the
following instructions ensures that the first time it is started there is proper lubrication on all internal parts.
Once the engine has been primed and run for the first time, a thin layer of oil always remains on all of the
bearings and protects them for those first few critical seconds during startup while the pressure builds up.
Priming the oil pump is the most important step to take just before starting your engine for the
first time!!
1
. After you install the engine into the Jeep
’s engine compartment, make sure that you install a
new name-brand oil filter such as Wix and fill the engine with the proper amount of oil. Using the factory
oil pan and oil dip-stick, fill to the factory level on the stick.
2
. Install the priming tool into the engine through the distributor hole and attach a
” electric drill
to the priming tool. If you don
’t have a priming tool, you may cut the handle off of a flat-head
screwdriver and use that to turn the oil pump drive shaft. Be careful, though, as the cut-off
end may be sharp.
3
. Next, turn the drill clockwise until you feel the drill load-up. This may take a few minutes, but
you will eventually feel the drill start to torque back on your arm. This is a sign that the oil has
now been pulled through the oil pump pick-up tube and is now actually pumping through the
engine.
4
. Continue running the drill for another minute after the drill loads-up. This ensures that all of
the bearings and moving components have been properly lubricated.
5
. After priming is completed, install the distributor and start the engine.
