Question about 1999 Saturn SL

1 Answer

I need to replace my intake manifold gasket on my 99 Saturn SC1 1.9L. I have everything removed and all the nuts taken off. I tried pulling the manifold off and the metal line coming from the power steering reservoir is in the way. I was wondering if there was a way to get the manifold off without having to remove this. Any ideas would be very helpful as this is very frustrating for me. Thanks

Tip

Stalling and running rough - Hyundai Elantra - 2001-05


The Hyundai Elantra 2001 - 2005, 2.0 L engine is noted for this problem. It will lack power on acceleration and run rough and stall while driving. The engine light will come on for misfire codes. This problem is caused by a vaccum leak at the intake manifold gasket. The gasket is broken and needs to be replaced.
To replace the intake gasket with a new one, remove the 12m nuts holding the intake to the cylinder head. Then pry back( note: you do not have to completely remove the intake manifold here) the intake manifold to gain excess to remove the old gasket. Remove any excess gasket and clean with brake cleans the surface area of the intake. Install the new intake gasket on to the head and carefully install intake on to cylinder head studs. Tighten up nuts gradually and evenly to 15-20 ft.lbs.

Why does my 99 saturn sl idle erradically sometimes?


One of 4 things. Your TPS [throttle positioning sensor] IAC [ idle air sensor ] vacuum leak, or intake manifold gasket getting bad.Easy test for you to do before you get into replacing parts is as follows. Start car, and take some engine cleaner spray, and spray directly onto the gasket where the intake manifold bolts onto the block. Spray liberally. If you hear the engine RPM'S change in ANY way, your gasket is bad. These cars are well known for this. I suggest that you try this first and get back to me. If this is not it, I can walk you through the next easy tests. Let me know, but if I were a gambling man, I'd gamble on it being the intake gasket. $40, and 2 hours to do it yourself. I also made a video while I was doing my own. Let me know if this info is helpful

Trying to figure out how to change my intake manifold gasket on a honda civic 97


  1. Take loose the intake tube from the intake and breather box.
  2. Remove the wiring harness from the intake mahifold there should be 4 injector plugs 3 plgs on the back of the manifold .
  3. You must take loose the fuel lines both the supply line on the left side of the fuel rail and the return line on the fuel pressure regulator
  4. Throtle cable must be taken off of the throtle body(and also dentent or shift cable if it is an automatic trans.)
  5. There is going to be a bracket on the underside of the manifold that more than likely will have to be gotten from the bottom should be a 14mm take loose from the manifold not the block
  6. There will be 8 to 10 12mm bolts that hold the intake manifold onto the head all of which are hard to get with the head still on the car but it can be done for a couple of them u will need a wrench and possibly even a swivel socket
  7. Remove the intake and pay attention to the hose that runs from the intake to the oil breather on the back of the motor its a bit tricky to get back on if u dnt have samll hands
  8. Make sure the gasket area of the intake and head are clean before installing the new gasket
  9. Reverse the instructions to replace the intake and make sure you torque the intake stud nuts to 16 ft/lbs

Will a 99 1.9 dohc fit my 2001 dohc


More or less, yes. As long as it is the 9 bolt exhaust manifold on the '99 then everything except the intake manifold will bolt into your '01. The intake manifold on your '01 is a vertical plastic type while the '99 has a horizontal aluminum type. Bolt off the '99s and put on your '01 and you should be set.

How do i remove the head from my saturn 1.9 engine?


Removing it isn't too hard, replacing it is another story. Drain antifreeze. The top radiator hose will need to be taken loose. Air intake from front of car to filter.The fuel lines...You just need to pinch the plastic clips with a pair of needle nose pliers while you pull on the lines.The timing chain will need to come off,make sure the marks are at top dead center, bottom and top sprocket. You will need to take off the EGR valve, The vacuum lines on top of the throttle body. Vacuum line under Air intake. Throttle cable, manifold exhaust, 02 sensor, A/C compressor if you have one, just lay it aside...doesn't need to be discharged. Power steering pump need to take the bolts out of it by turning the sprocket so you can get a deep dwell socket in it...about 3 or 4 bolts there. The tension pulley needs to be taken off, of course after the belt is taken off. A few other things that are obvious by looking. Most importantly, have the head tested before putting on new gasket. The bolts should all be replace on the head since they are torque to yield. The torque procedure is 25lbs, all then 35lbs. all then turn the wrench on all of the bolts from 12 o'clock to 3 o'clock which equals 90 degrees. That will give you the torque to yield...
