Remove the exhaust pipe from the exhaust manifold. Remove the manifold bolts. Remove the manifold. Remove the manifold gasket and clean the surface. Reverse the process to install the new manifold gasket.

Hi..I recently had troubles with my alero, and it was the intake manifold gasket, which i guess is a common problem with 2000 alero's...i would get that checked out

The Lower Intake Manifold gasket. Do a search on that in Google, the Chevy Malibu and the Pontiac Grand Am and the Alero all have the same motor with the same problem. Yay!

you can go to any auto parts store and get a Hayes repair manual this will tell you how to fix your problems. Hope that will help with your intake gasket problems

$2200 is what I spent but it was head gasket and intake gaskets.

On a 1999 Oldsmobile Alero, the knock sensor is located on the engine block. It may be bolted to the intake manifold, or to either side of the block.

Remove the valve cover retaining bolts. Remove the valve cover gasket and clean the gasket surface. Put the new valve cover gasket on and return the valve cover to its original position.

As Long as Your Alero has a 3.4, You should be good. #1 - You will need to change the timing cover, some of the pulleys are in a different spot. #2 - The motor mounts are different, they will need to be changed over. #3 - The fuel rails connect in a different spot on the engine, you can change them if you want, but it's not necessary. FYI - 3.4 is notorious for Lower Intake Manifold Issues until 2004. The gaskets leak because they are plastic. If you're going to buy a used motor, look for coolant in the oil and around that manifold area first before you buy. The gasket set is about $120, and it takes a few hours to replace them.

These cars do not have a distributor or gasket. They are run on a coil pack which is controlled by the ECM.

Any parts store can provide you with the correct gasket.

The cost to replace the head gasket of a 2000 Oldsmobile Alero costs between $20 to $190. This depends on where the part is bought, the brand of the park and any costs concerning labor or shipping.

Take the old one out and put the new one in. You will have to remove the rubber snorkel from filter to intake plenum in order to get at the filter.

Sometimes the coolant will burn away before hitting the ground, and you will not see it. A pressure test needs to be done on the system. Some common areas of leaks on the 3.4 v6 is the intake manifold gaskets, water pump, or headgaskets. - TechJK ------------------------

The O2 senors will be in the exhaust system. They may be in the exhaust manifold all the way to the convertor. You can locate them easily. They will be the only thing in the pipe or manifold that have wires attached to them.

The pinch welds under the car indicate where you put the jack to change the tire on a 1999 Olds Alero. Look under the rocker panels.

on my 2002 alero I havw the 2.2 4cylinder ecotec engine, on the intake there is a cover that says 2.2, remove the four bolts and the plugs are down in the little cylinder holes mine require a 5/8 spark plug socket and you will also need an extension.

Could be a few different things. Spark Plug, plug wire, coil, injector, ignition module (these are most common) Head gasket, cracked intake, mechanical (ie valve,piston,cam etc) (less common)

Many things can cause the car to overheat. 1. Low coolant caused by leaking hoses, water pump, intake manifold on v6 engine. 2. Bad headgasket on v6 engine causing coolant to overflow out of the reservoir jug. 3. Stuck thermostat. - TechJK ETC. -----------------------------------

Every 50,000 miles, is not easy to do, you have to take out the pan under the car at the left side. Remplace the filter and the gasket... be sure before start to buy the filter kit, around $22 dollars.
