1. Are you absolutely certain that the timing chain NEEDS to be replaced? Generally, a timing chain is only replaced when rebuilding the engine. Saturn timing chains generally last until the engine has worn to the point that other internal work should be performed.
2. If you are CERTAIN that you need a timing chain, the easiest way would be
- remove the engine from the vehicle, but you CAN simply pull the passenger side fender cover and try to work in that tight space.
- Pull the dampener pulley (that's the big pulley that drives the serpentine belt.
- remove the front engine cover. In the Saturn it is also the oil pump.
- remove the timing chain tensioner assembly and make certain that you do not misplace any of the internal pieces... the spring will fly across the room if you aren't careful.
- Remove the timing chain guides from both sides of the engine and the third one from the head (twin cam only).
- turn the engine to #1TDC. note the timing holes on the camshaft(s). They should line up with a matching hole on the head when the engine is at #1TDC.
- Disconnect the cam sprocket(s) and remove them, taking care to not turn the crankshaft or camshaft(s).
- Put the new timing chain and sprocket(s) in place, making certain that the camshaft sprocket(s) line up with the alignment hole(s). This step assumes that you have not turned the crankshaft away from #1TDC. Tighten the sprockets.
- Install the new timing chain slides in the original position.
- Use the retainer to hold the chain tensioner while you install it. Sometimes a helper can be beneficial in this procedure.
- Install a NEW dampener pulley oil seal.
- Replace the engine cover/oil pump assembly, making certain that all surfaces are clean and that new gaskets have been used.
- Install the dampener pulley, making certain that the key is properly installed.
- If necessary, re-install the engine.

Does a 1994 Saturn with a 1.9 liter engine have a timing chain?
Yes, a 1994 Saturn with a 1.9 liter engine typically has a timing chain rather than a timing belt. Timing chains are more durable and typically do not require regular replacement like timing belts.
Does the 1987 22re have a timing belt or timing chain?
The 1987 22RE engine has a timing chain, not a timing belt. Timing chains are generally more durable and are designed to last the life of the engine, whereas timing belts need to be replaced at regular intervals.
Does a 94 mercury topaz have timing chain or belt?
The 1994 Mercury Topaz has a timing belt, not a timing chain. It is recommended to replace the timing belt at regular intervals as part of the maintenance schedule to prevent potential engine damage.
How often do you need to change the timing belt in a 94 mercury topaz?
It is recommended to replace the timing belt in a 1994 Mercury Topaz every 60,000-100,000 miles. It is important to follow the manufacturer's guidelines to prevent potential engine damage due to belt failure.
If the timing is off in a '92 Mercury Topaz how do you fix it?
To fix timing issues in a 1992 Mercury Topaz, you will need to adjust the timing belt or chain. This involves aligning the marks on the crankshaft and camshaft to the correct position using a timing light. If the timing is severely off, you may need to replace the timing belt or chain altogether. It is recommended to refer to the vehicle's service manual for specific instructions.
