quick TB question
getting ready to tackle the timing belt, water pump, and thermostat with a friend. this will be my first major DIY. i searched the tech section and the best i could find was a guide for the 1.8. i have the 2.8 so im wondering if the 1.8 guide will be sufficient enough to get us through. Thanks Ahead! Larry

You don't need a timing bar, or a crank lock. Mark the old belt and each cam pulley, along with the crank pulley too. Then remove the belt, count the teeth between the marks and mark the new belt accordingly with a paint pen (white or orange show the best). It's easy. Make sure you mark which mark goes to what pulley.
I always make sure #1 is at TDC according to the harmonic balancer, the make sure that the large holes in the cam alignment "ears" are pointing towards eachother. |

LOL...
Don't use a bar. I like buying cheap Audi's with smashed valves. It happens ALL THE TIME. You can replace the cam tensioner seals with removing sprockets but not the cam shaft seals. |

These were total loss engine failures. Also as mentioned the timing bar is needed to manually tension the timing belt on 12V V6 engines. |
Youll get a fault also if youre "close enough". Cam position sensor bank whatever. Also dont you have trouble with the cam spinning back bc of valve tension? I saw this at work recently on a water pump job, once the bar was removed the pass side cam would snap backwards about 10 degrees or so.

welp it took a little longer than expected haha ok actually alot longer. but my buddy and i took our sweet time. we didnt use the bar just put the necassary marks. did the water pump and thermostat while i was in there. Ive put almost a thousand miles on it since and i tore s*** up in two snow storms. Shes running good as ever. This was my first diy minus an oil change so as long as you have common sense i would recommend this job to any aspiring diy'er.
