I had a hole small hole in one of the manifold covers on my truck, noticed it after I saw lots of steam coming out of it, so I used heat tape( got from Checker Auto Parts) to cover it, and to date it's still holding. (mind you this is only a temporary fix)
This is a common problem for all Saturn S-Series 2000-2002. The plastic intake manifold cracks at the coolant stems, even if the engine does not overheat. This is especially true in the southern half of the US (hotter climate). The intake manifold would need to be replaced, or repaired so no further damage will occur like overheating the engine. CarSaturn of Conyers, GA sells a repair kit to fix this problem- Worked for me. Link is below www.carsaturn.com Good Luck!
It seems to be directly under the intake manifold, which is closest to the firewall, if you from the drivers side fender you can see about half of it through the holes in the intake manifold
in between the intake manifold, bottom half.
The sensor is located under the intake manifold. It takes about 2 and half hours to replace the intake manifold, book time. Knock sensor is about $35 + $60-$90/hr labor. So you are talking about $300.
I don't know for sure, but I DO know that the intake manifold is a faulty design (thin plastic?? wtf!) which they released an aftermarket replacement for which has METAL on one side. A common problem is a crakced intake manifold on these cars- mine's like that (90% sure) and oil is getting into one side of the spark plugs causing them to crap out needing often replacement. This problem is endemic, if you replace it with the new half-metal manifold it should be fixed. Hopefully!
i think u r talking about the MAF sensor or mass air flow sensor which is like half way between the air filter and the intake manifold on the air tube
Not sure if this is your problem, but my 1996 Olds Cutlass Supreme leaked coolant into the oil. This was caused by broken intake manifold gasket. Apparently they're somewhat notorious for developing leaks. That repair required taking the top half of the engine apart. Not sure where your leak is, or how much it's leaking, but you may want to consider the intake manifold and head gaskets.
the firing order is stamped on the intake manifold, it's 1-8-4-3-6-5-7-2
I have a 1994 jetta. easiest way is to take the intake manifold off using Allen screws. Be sure to catch the gasket between the upper and lower half of the manifold. This gives easy access to all spark plugs.
It attaches on the inside of the intake manifold. Tkes the vortec cover off and then the top cover of your intake mainifold. I know it seems wierd but it is actually a two part intake the will seperat in half. you will then see the4 fuel dilivery system and the fuel lines.
Ontop of the motor youll see a 9mm (i think) bolt head popping up infront of your intake manifold. Undo half way as it has a slot cut half way up the thread to vent.
Spray starting fluid around the engine. its probably the pcv elbow beside the exhaust manifold or the pcv end assembly elbow on the bottom of the intake manifold. Mine had both elbows almost in half.
