2001 Toyota Highlander 6 cyl Four Wheel Drive Automatic 119000 miles
2001 Toyota Highlander, V6 3Liter, I am changing the timing belt & water pump as part of a major service. Following the manuals instructions step by step I removed everything in the way and had access to the belt.
The crank shaft mark was on “O", both cam shaft marks were lined up with the marks on the their heads.
The instructions then said to rotate the crankshaft counter clockwise 60 degrees, then release the tensioner pulley, and remove the belt in a set sequence.
When I removed the belt from the cam shaft on the front of the motor, it spun about 30 degrees.
First instinct was to put all parts in box, have car taken to garage – let them
fix it !
I have done 5 or 6 timing belts before, but never had anything move when I removed the timing belt before.
Still willing to try and do this myself if I can do so without ruining motor.
If I go ahead and install the new water pump, without disturbing any of the shafts, then move each shaft back to its timing mark, install the new belt, then rotate the motor numerous times – as long as each time the crankshaft mark is on “O", both cam shafts line up with their marks, then:
1. Best case, all is well, car will run as designed.
2. “Worst" case, car will not run – BUT neither of the heads will be smashing valves on pistons because the marks mean that at TDC the valve will always be in an ok position relevant to their pistons.
I appreciate any advice to get me successfully out of this situation !
have the same problem?
