The V70 Timing Belt Change can be done without removing the crank pulley.
I’ve been using VADIS instructions and some of Volvospeed’s instructions for the 850 and talked to MIJ a couple of times.
I did go clockwise 1/4 turn from when the marks lined up and then back before removing the belt.
I had a heck of a time getting the new belt on and the marks lined up with the tensioner adjusted properly. I had to do it over about 5 times to get the tensioner right and the marks all lined up.
After this last time, on the crank, the mark is in the marked sprocket “valley” but to one side of the valley (before I took it all apart it was right in the middle of the valley. On the cams, they are lined up right on the mark.
Anyway, after redoing this so many times and adjusting the cam pulleys a sprocket one way or the other several times, I am pretty apprehensive about starting the car.
The last time I redid it, I also ran the crank 1/4 turn past on the mark and then back before removing and readjusting the belt and tensioner.
My quesion is, if it’s not lined up right is there a way to tell without taking the valve cover off and before trying to start the engine? I’ve rotated the crank about 6-8 time and I don’t feel anything (except the compression – left the plugs in) and I dont’ hear anything (metal clanking or scraping). Does that mean it’s OK?
Thanks in advance!
Scroll all the way down. The whole process took about 3 hours including removing engine mount and replaced the serpentine belt tensioner. So far I’ve used the whiteout trick on a 960, 850 and the S40. It should work on every whiteblock.”
