Timing belt how to because that 3.5 Pacifica
I did mine wife"s time belt and water pump yesterday. Pretty simple straight front install. I see a lot of of human being asking around it therefore i figure while it"s still new in my head ns jot down a quick how come procedure. Action one, disconnect the battery2) take the plastic 3.5 lid off of the engine3) take a screw driver and also loosen the water tap clamp through the throttle body, disconnect the sensor top top the air intake rubber hose, and take a 10mm socket and loosen the bolt ~ above the rad support that holds the air filter canister. Once that is done, wiggle the whole air intake device off that the car.4) jack increase the car, assistance the auto with a suitable jack stand on the sub frame behind the wheel so you can obtain under the car later. Remove the plastic within fender near the prior of the wheel well the covers the Ac compressor. There space 2 plugs in the wheel wel, one top top the lower framework under the rad, and also two are in the inside structure of the engine compartment.5) drain the rad. Ns took turn off the lower rad hose because I to be replacing the anyway.6) currently that the vehicle is in the air, gain a floor jack with something solid and also flat to support the oil pan7 ) v a 15mm socket, take off the 3 bolts ~ above the motor mount that"s attached to the motor, climate the 2 15mm bolts for the mount the is top top the framework of the car.8) Take off the serpentine belt by placing a 3/8 drive right into the tensioner and pull it back and remove the belt. Time to take it the bolts turn off of the timing cover. I m sorry I first took off all the 10mm bolts that I could see (2 at the top, 2 in ~ the rear side close to the fire wall), then with a 1/2" socket, eliminate the 2 at the optimal of the cover. Take it a photo of the pullies on the engine so you know how they go earlier on. Then remove them. They space all 15mm bolts. Behind the tensioner there is one more 15mm bolt that needs to be removed.

9) with a 1/2 quick socket you need to rotate the pwr steering pulley until you check out 3 bolts holding the on thru the circle feet in the pulley. There you will certainly find one more 10mm bolt securing the time cover on. Top top the left next of the time cover you will see 2 15mm nuts that additionally has to be removed.10) v a 18mm socket top top a influence drive, Zip turn off the harmonic bolt. Then with the suitable puller remove it. (it must have actually a expansion that goes within the harmonic, not your classic 3 prong puller)

17) currently the liquid record comes out and also I note the notch in the video camer spockets and belt.What functioned well because that me to be to put on the brand-new belt and also take the slack the end from the crank pillar pulley to the ideal side time sprocket. So as soon as the tensioner is tightened later, that part doesn"t move. Gain the new tensioner, loosely install it so there is currently tension top top the belt. Placed the belt ~ above the left side video camer sprocket, yet take the notch and also rotate it 2 cog belt notches front so the 2 present don"t accomplish up. Climate tighten the tensioner and also it will turn that sprocket earlier to line up the marks.
