It pushes in and uses an oring seal on the little tube.I tow with a Jeep Grand Cherokee 3.0CRD ( Mercedes Diesel) and honestly cannot fault it.Permanent 4WD , 215bhp, 500nm of torque and over 2 tons in weight make it a good towcar I get 22mpg towing an Eldiss Odyssey 544 and around 27 solo. Taking it easy on a solo run i can top 30mpg. The 2.7 will be very capable and more importantly reliable. Darryl
2002 2.7crd grand cherokee wont change gear. « on: November 19, 2006, 13:45:30 ». Hi all, my Jeep has just stopped changing gear, it will go into reverse and forward gear but will not change upwards; max speed of 40mph. The fault light that looks like a gearbox has also come on. There is no dipstick to check the oil for some reason.
Laura. Discussion starter · Dec 13, 2020. Hey! I have Jeep Grand Cherokee 2.7 crd. After changing fuel lines at high pressure pump my jeep wont go over 1.5k rpm, it just turns off engine. Check engine light is on and the P0403 code is up. Maybe i mixed the fuel lines up? ma0PZ3V.
