How to set timing, 1992 saturn SL2 DOHC - 1992 Saturn SL2

There are 2 different engines for the 92 SL,they are 1992 Saturn SL 1.9L TBI SOHC 4cyl 1992 Saturn SL 1.9L MFI DOHC 4cyl Here's a link to the blower motor resister,it's located next to the blower motor,2 screws hold it on.

If you are replacing a DOHC 1998 engine with another DOHC 1998 engine yes it will work. Saturn only made two engines from 91-99 and they all had the same block, difference some were SOHC and others were DOHC. The number "1" after SL or SC or SW means SOHC while the number "2" after SC or SL or SW means a DOHC.

Note if one is an auto and the other manual you are going to have to swap the flywheel/ring gear stuff over.

that means your rings, valves, or head gasket are going bad beyond the normal aging of all the cylinders. the number 3 was the first to go on my 91 DOHC too. the car is nearly 20, and that stuff happens with age and use. I would look around for a low mileage DOHC Saturn engine from a 94 SC2 or SL2. the engine is so old that to fix it you will have to rebuild it which will cost far more than the 500 dollars the whole car is worth. the same engine was in them from 92-94, possibly even a 95. make darn sure you find a DOHC engine and not the SOHC, they look almost the same but they are not interchangeable unless you change the transmission, the exhaust, all the wheels, and the speedometer.

Hope this helps (remember to rate thsi answer).

no, the plug wires snap onto the plugs which are in deep recesses in the valve cover on the DOHC, which is the SL2. On this old car you may just want to replace the plug wires at the same time unless you are sure they are less than 5 years old. get some good wires, not generics, that are made for the car.

On the SL2 (DOHC), there are two coolant temperature sensors located on the left-hand side of the cylinder head, near the upper coolant hose. On the SL2, the upper sensor with ONE WIRE controls the temperature gauge in the dash. The lower sensor with TWO wires provides input to the computer. They are not interchangeable. Here is a tip you will need a 14mm deep socket or box wrench. The new sensor may require a 13mm socket or wrench, depending on the manufacturer. Good luck and hope this helps. Keep me posted.

You'd probably have to get a reprogrammed or chipped engine computer. Removing the rev limiter though is a sure fire way to destroy your engine. Even Ferraris and Porches have rev limiters.

These engines have a timing chain, not a belt. They also have nylon coated guides under the cover that wear. If you change the chain yourself, or have it done, check the guides as well.

Did you check fuses?
