It all depends on the terrain and the driving method that is followed as a lot depends on the fuel consumption if the terrain is hilly and the traffic condition is worse. Use of AC is another factor.
You can have your fuel pump checked or calibrated for a final assessment only if you notice smoke in exhaust.... Not sure of your mileage clocked to know the state of the engine but have the scheduled maintenance done accordingly..

When I went back I'm using cruise for 100 km/hour and towing a motorcycle? on the top hill.(edited)


ok its a 2008, MK49 jeep, Patriot
no engine stated.
gas or diesel, or turbo diesel.
if its the VW diesel
it is really 3 cars in one.
Jeep, Mitsubishi and VW.
not a fun job to fix or diagnose, cars like that.
mixed parts...
but gas dirt cheap here, at 50 cents a liter.
so we run nice big V6 here. common on all jeeps.
3.7L petrol.
getting diesel smog clean is problematic. (NOX issues huge)
see the VW law suits. yah. more pain.

so what engines is really really there

How do you bleed a diesel pump jeep Cherokee turbo diesel 3.1 5 cylinder 2001


we dont have this engine here, USA.
but i have the WG jeep book,
starting page 12 , chapter 14


FUEL INJECTION PUMP BLEEDING
(1) If the fuel injection pump has been replaced,
air should be bled at the overflow valve before
attempting to start engine.
(a) Loosen the overflow valve (Fig. 18) at the
rear of the injection pump.
(b) Place a towel below the valve.
WARNING: WHEN CRANKING THE ENGINE TO
BLEED AIR FROM THE INJECTION PUMP, THE
ENGINE MAY START. PLACE THE TRANSMISSION
IN NEUTRAL OR PARK AND SET PARKING BRAKE
BEFORE ENGAGING THE STARTER MOTOR.
CAUTION: Do not engage the starter motor for
more than 30 seconds at a time. Allow 2 minutes
between cranking intervals.
(2) Crank the engine for 30 seconds at a time to
allow air trapped in the injection pump to vent out
the fuel injector drain tubes. Continue this procedure
until the engine starts. Observe the previous WARNING
and CAUTION.
(3) Tighten overflow valve.
HIGH-PRESSURE FUEL LINE BLEEDING
WARNING: THE INJECTION PUMP SUPPLIES HIGH-
-PRESSURE FUEL OF APPROXIMATELY 45,000 KPA
(6,526 PSI) TO EACH INDIVIDUAL INJECTOR
THROUGH THE HIGH-PRESSURE LINES. FUEL
UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE
THE SKIN AND CAUSE PERSONAL INJURY.
WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE
CLOTHING AND AVOID CONTACT WITH
FUEL SPRAY WHEN BLEEDING HIGH-PRESSURE
FUEL LINES.
WARNING: DO NOT BLEED AIR FROM THE FUEL
SYSTEM OF A HOT ENGINE. DO NOT ALLOW FUEL
TO SPRAY ONTO THE EXHAUST MANIFOLD WHEN
BLEEDING AIR FROM THE FUEL SYSTEM.
Bleed air from one injector at time.
(1) Loosen the high-pressure fuel line fitting at
the injector (Fig. 19).
(2) Crank the engine until all air has been bled
from the line. Do not operate the starter motor
for longer than 30 seconds. Wait 2 minutes
between cranking intervals.
(3) Start the engine and bleed one injector at a
time until the engine runs smoothly.

Transmission dip stick keeps popping out


check trans. fluid level per owners manual.The high operating temperatures cause fluid to expand greatly,an over-filled transmission can actually force excess fluid out of the dip stick tube.check level with trans. hot,engine running in park on a level surface. After driving,place shifter in park,hold brake and move shifter through all gears and back to park.remove dipstick,wipe clean,re-insert and check fluid level.normally,trans fluid & filter should be changed +/- 100 k miles

I have a FORD Econolinen 1993. When I drive he abuse 45 ltres of gaz on 100 miles . Is this normale ?


on normal that trk should be around 6-7 gallons used per one hundred miles drove. i based that at 15 mpg. now that is also based on a V8 engine. now 1 gallon of gas is 3.78541178 liters which totals 12 galons of gas to 45.42494136 liters. This would mean that it took 12 gallons of gas to travel 100 miles which totals 8.3333333333 mpg. not as good as i would have thought. 8 miles per gallon (mpg) hell that engine must be a big block 460. If it is that big cubic inch i could understand but any other motor should do better mpg than 8.3. so i agree that is not normal, tune up, or look for fuel leak in the fuel supply or( feed ) line. From the tank to the motor. This must be a canadian truck yes? well hope for the best or trade that guzzler in for a new breed. stay warm!

How much and what type of coolant does a 2002 Jeep Grand Cherokee use?


depends on engine ,if you buy five litres of pure 100% antifreeze any colour and drain some of the rad then add this it will be ok ,if your in the artic circle then just use 100% and add neat no problem .so long as its eythlene glycol you cannot go wrong ignore the pundits with their usual brown stuff from bulls ,the colour is immaterial the basic ingrediant is all the same so it doesnt matter about mixing it at all .i live in spain on the med coast where it never freezes or gets cold and i use 100% in everything i repair ,its an anti corrosion inhibitor as well as antifreeze so just drain some off add a minimum of 2 litres and you will not be far out ,unless you in alasaka on the ice road truckers run .nice motors these jeeps as long as its a diesel with a manual gearbox .

The car's peformance has been poor, especially on picking from a stationary position (no power).


I would suggest to have the pump timing reset and probably have a diesel specialist to check the pump as well. It is very difficult to give extra help over the net as most of the things have been covered by the mechanic I supposed. But as per your description I think the pump may have not been timed properly or it may need overhauling as well.
