Question about 1987 Porsche 944
Hi my name is spencer,
The timing belt on my 87 944 recently started vibrating a bit and hitting the platic belt cover making a terribly annoying noise. i popped the hood and took the cover off to check the tensioner and it was all the way out (as tight as it would go). so i bought a new belt and the electronic tensioning tool because i have more than one 944 for i figured it cost effective to learn how to do it myself rather than take them in all the time. well heres the real problem...while fooling around with it a bit my friend said he read somewhere that youre supposed to turn the crank a half of a degree to reset the tension on the belt.we didnt have a socket big enough to fit on the crank bolt so he suggests he take a fuse out and just crank it over for a half second.foolishly i agree thinking he knows what hes doing since hes rebuilt numerous cars.when we do this the belt jumps and i believe it just skipped a few teeth.i need to know the process for lining up the cam and crank shaft finding tdc and putting the belt back on with correct tension. Anyone have any ideas?
There is a gear in the speedo that breaks. This is plastic gear on a metal shaft. The last fix I did was to remove speedo and open it up. I super glued the cracked gear to the shaft because I was unable to find a new one. It worked again with no future problems. I hope this helps.

Timing belts on 944s NEED to be changed every 30k miles. It can be a challenging job. I would recommend a shop. Balance belts, rollers and usually a water pump replacement is recommended at the same time. Cost, approximately $1400. Parts can be purchased cheap, but labor is 8-9 hrs.
If you decide to do it yourself you will need a specific timing belt tensioner gauge tool.

it could be the temperature switch in the radiator. the temperature switch is under the air box and splash gaurd. it is screw in the radiator over the flow out pipe

Sounds like a possible fuse problem. Have you checked your fuses yet. If not look in your owners manual to see which fuse(s) control your instrument panel, or anything else you are having trouble with. Keep in mind, if a short did occur for some reason, more than one fuse may be blown. When i accidental crossed two door lock wires, i blew 6 fuses, some of which were not even related to the wires i crossed. Hope this helps
