if it is a 2.5L it should be 12 degrees before t.d.c.
The timing can be adjusted by loosing the 2 bolts that hold the distributor on any pre-1989 740s. Be sure your timing belt is installed properly too. Another note here, the harmonic balancer on the 4 cyl Volvo has a rubber mounting between the inner part that attaches to the crankshaft and the outer part that the drive belts go around. They are known to slip. If your timing is way off, put a small white paint mark on the crank pulley and rev the engine a few times while watching it with a timing light. If it is changing positions a lot then you are going to have to replace the balancer before it comes completely apart. you cannot set the timing in a 740. if it doesn't run, it's not right. No one said it did not run. Timing belts can be off as many as three teeth and still run. Over 35 years in the Volvo business myself. Do note the question was about a 1990 Model that is a crankshaft position sensor fired car. The timing is not adjustable on a 1989 or later as the above answer states, PRE-1989
I own a 1989 745 Turbo Wagon &, a 1996 960 both absolutely trouble free.
Yes. However it's not that easy due to the turbo versions electronics (if it's a 700 series turbo your after). But fully possible and has been done several times.
you cannot fix the timing on your tbird as it is electronically controlled and does not have a distrubutor. have your camshaft or crankshaft sensors checked
The 1989 Volvo was offered in the model 244 with a 2.3L L4. The gap for this application depends on the spark model and electrode material. Iridium and platinum plugs for the application come pre-gapped from the factory.
Adjust ignition timing. check knock sensor.
its a ct26
Turbo Outrun happened in 1989.
