The water pump went bad, I change out the water pump and the thermostat and put in antfreeze, and the engine still overheats. does it have something to do with the exhaust?

It could also be a clogged heater core. Your radiator fluid flows through it and is how your heater works to keep the car warm in the winter, but if it's clogged will not heat well and can cause your car to overheat.

It could be either the radator or the timeing is too far advanced. Did you put a 50/50 mixture of antifreeze? To much antifreeze vers water will also cause overheating. Non Exhaust.

Overheats when the a/c is off

if the thermostat has not been replaced i would do this, also while doing this flushed the radiator system out, is also best to back flush they system, also when was the last time the water pump was changed, as over time the fins on the water pump will deteriorate and cause overheating problems, with a/c it will help keep the engine cooler, but you need to check that the parts ive said have been done as this is the main cause of the engine over heating, you will probably find the thermostat is not working properly and there is rust red water in the system, and rusty parts in the emptied water thats why you will need to back flush the engine youtube back flush engine, top up with new antifreeze recommended for your area and engine. and bleed out the air from system. if the water pump has not been replaced in 5-10 years it needs changing.

I have a 1998 saturn SL2 with a LL1.9LL4 engine, want to switch out with a 1998 saturn SW2SW wagon with a 16 valve twin cam will this work? SL2 engine blown, SW2SW ****** is going!

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.

I have a 2000 saturn sl1, and i seem to be putting coolant in my car at least 2 times a week. It also overheats and when it does, it comes out of the top of the part that hold the coolant. Could this be my...

If it is coming out of the top of the radiator, you are getting back pressure. First, make sure there are not puddles under the engine where the water pump is at. If so, you will need to replace the water pump and gasket; as well as the thermostat. It sounds as though the thermostat is stuck closed - replace it (if no leaks from water pump) and see if this fixes the issue.
Also, start the car (radiator full) and let run to operating temperature. Feel the top radiator hose - if it is not hot, but the engine is, then the thermostat IS stuck closed. Be sure to ask for a thermostat housing gasket when purchasing the thermostat, as they do not always come together.
Please let me know if you need further assistance.

My S belt snapped on my 2000 Saturn SL2, and the engine immediately over-heated, and something cracked, causing radiator fluid to leak everywhere. I was told by a friend that it's part of the heating...

282420f.jpeg Does your engine look similar to this. IF you're referring to the wording on the cover, this is the valve cover. This is the only piece i'm thinking that has this. But this should not leak radiator fluid to leak. With the car overheating and something cracking, it could be the radiator busted or the head/block could be cracked. Try to fill the radiator up and see if it starts leaking. I'm just wondering if your water pump locked down or any of the other pulley's causing the belt to snap. If you would like send a picture to me at of the part and I can better help you.

My 1998 Saturn SL is not running as smoothly and

Wow, that's a tough one, if you've done all that and it still overheats, I would try replacing the temp sensor, maybe it's faulty. Plus they're pretty cheap( I like fixing things for cheap)
If that's not the problem you could try a lower temperature thermostat, and if that doesn't work I would suspect that something is preventing the coolant from moving through the block effeciently.
Where is the temp sensor?
I had a Buick that the temp sensor was on the top of the block and if the coolant level went down AT ALL it wouldn't cool the sensor and it registered as dangerously hot and give me a heart attack in the process.
As for a tune-up get anew distributor cap, rotor, spark plugs( and spark plug wires if you want it to REALLY be tuned up)
This will probably cost you in the range of 50-100
bucks, but a little preventive medicine goes a long ways.
I had a bad plug wire I thought was an ignition problem and spent 300$ in parts trying to fix.
One day I went "I wonder if it's the plug wire?"
I bought one for 8.88$ and now it runs like a brand new car.
Hopefully one of these things will work.

yes that is your problem. the water pump is made to turn clockwise. when the engine runs it turns clockwise right! if it turns counter clock wise it will not circulate coolant and it will over heat. the only thing I can say is the drive belt may be on wrong causing it to run backwards.

Belt tensioner assmebly went bad

Take the Right hand front wheel off, remove the plastic splash panel. Obviously, first remove tne belt. the tensioner should be slightly up in the wheel opening. Remove the pully, center bolt, remove the bolts attaching the tensioner asm. Local autoparts store should have replacement for around $30.00. Replace follow instructions backwards. While at auto store reference saturn manual for torque to tighten bolts when replacing. Do not over torque into aluminum block.

My 94 SW1 did the same thing, that is the same basic engine but a SOHC. I replaced the crank position sensor which is in the block behind the starter and the problem went away. There are most likely other problems which can cause stalling, vapor lock due to bad gas cap for one, but mine was fixed by replacing the sensor. Bit of problem getting to it, but you were already in the area when you replaced the fuel filter.
