Riding along with cruise control at about 55mph when suddenly the engine rpm increased then dropped off as I heard something like a "snap". Engine just turns over now but doesn't start. I'm guessing it's the timing belt. It's got 150,000 orig miles on it.
The 8th VIN number is a "3". Believe this is a 2.0 DOHC engine. Is it going ot be worth my while to buy all the parts and replace the timing belt, idler(s), tensioner and wter pump? Is this a "free floating" engine?
Thanks, George O.  

planning on doing it your self?????

you will have to pull the valve cover and timing cover...

there are no timing marks on the sprockets... there are no keyways aligning the sprockets on the cams...

the cams are aligned with a bar through the back end of the cam...

the cams do to the design... and it cannot be fixed...  will move when you set them at the perfect point.. so you have to lock the cams carefully....

there are also several tensioners and idlers... that should be replaced...

you with that kind of mileage also really need to change the cam and crank seal...  if you loosen the cam sprockets.. you will have to have the special tool to align the back of cams.. while the sprockets are loose... you also have to hold the sprocket when torquing the sprockets so you don't break the camshafts...

i don't know if that is a free wheeling motor.. i will check and post again...

there are instructions online at

the belts have been replaced without loosening the sprockets.. just by pulling the valve cover... and aligning the back by eye..

putting a bolt with a pair of fender washers installed lightly between the sprockets to hold them in alignment while you drop the belt on... and put the tensioner against the belt to take up the slack...  be careful not do damage the cam sprockets....
