The timing mark for the crankshaft on the 1989 Volvo 740 Turbo is typically located on the harmonic balancer. It should align with a corresponding mark on the engine block or timing cover when the engine is at top dead center (TDC) on the first cylinder. This alignment ensures proper timing for the engine's operation. Always refer to the service manual for specific details regarding your engine's configuration.
To change the timing belt on a 1989 Volvo 240 DL, first disconnect the battery and remove the front engine cover. Align the timing marks on the crankshaft and camshaft to ensure proper timing, then remove the old timing belt by loosening the tensioner. Install the new belt by following the same routing as the old one, ensuring it's tight but not overly strained, then reassemble the engine components and reconnect the battery. Always refer to the vehicle's service manual for specific torque values and procedures.

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
You can find a picture of a 1989 Nissan Pulsar crankshaft timing marks in several places online. Websites like automotive forums, Nissan enthusiast communities, or repair manuals such as Haynes or Chilton often provide detailed diagrams.

On a 1989 Volvo 240 DL, the crankshaft position sensor is typically located near the crankshaft pulley or the front of the engine, often mounted on the engine block or transmission bell housing. It is positioned to detect the position and speed of the crankshaft as it rotates. In some cases, it may be integrated with the ignition system components. Always consult the vehicle's service manual for precise location and installation details.
The fuse box for a 1989 Volvo 740 Turbo Wagon is located under the dashboard on the driver's side. You can find it by looking to the left of the steering column, near the side of the dashboard. There may be a cover that needs to be removed to access the fuses. Additionally, there is a second fuse box located in the engine compartment for certain circuits.
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.
