The spark plugs in an Olds '95 "quad four" are located under a metal shroud on the top of the engine. It also houses the coil packs and a unique coil pack holder which sets directly above the centrally located plugs. There are no plug wires, nor will you find a distributor.
You don't say what size of engine you have, if you have AA 6 cylinder, there are 3 plugs/wires in front of the engine and 3 in the back. You might have to take off your dogbones in front to pull the moter forward to get to the back plugs. If you have a quad 4 engine, they are under the intake manifold , on a quad 4 there are no plug wires, the spark plugs hook into spark plug towers . There are 2 bolts in the top manifold(where it says quad 4 ohc) and 2 bolts in the back, undo these and take off the manifolld and the plugs are right there.Hope this helped. Bratt
Remove the cover that reads Quad 4 then you will see the spark plug boots
I have a '95 grand am quad 4, 2.3 liter engine. The 2.3 quad 4 engine has the spark plugs underneath the ignition module cover, which is the cover that has "Quad 4" written on it. You have to remove this cover to get to the spark plugs. To remove the cover, you have to first unplug the negative batter cable and then unplug the crankshaft sensor from the ignition module housing. The cranshaft sensor is the plug that is to the top right of the ignition module housing. After you have unplugged the sensor, you have to unscrew the four bolts that are on top of the ignition module cover. After you've done that, you can lift the cover directly up. This disconnects it from the spark plugs. When purchasing new spark plugs, make sure you get the right ones for the engine, adn you can ask the guys at the shop to set the correct gap for you.
Answerwhat size is the engineIf it is the 2.3 engine they are under the top engine cover 4 or 6 maybe even 8 can't remmember spark plug boots are attached to the under side of the cover also there should be an electrical connector at drivers side of the engine cover you need to disconnect if it is the Quad 4 engine it should say Quad 4 on the engine cover you need to remove to get to the spark plugs.
quad 4? on top of the engine remove 4, 13mm bolts of the coil pack and pull up.the spark plug should be visible
They are under the coils. Which are next to the fuel injectors.
You need to unbolt the metal casement, that will say 'quad.." then lift up and remove spark plugs. If you have already gotten this far, then you probably don't need any more advice. We are trying to replace plugs on a 94. and Can't get it to start again.
The spark plugs are located under the silver plate on top of the engine. There are 4 bolts on that plate to remove - 2 right above the "16V QUAD 4 DOHC" notation on that plate; and 2 more, slightly farther apart than the other 2 and closer to the driving compartment.
quad 4 does not use spark plugs This must be a joke all gas motors use spark plugs yours are under the metal cover w/ 2.4 or 2.3 on it rite on the top of your motor
they are under the idi cover, its on top of the engine, 4 bolts hold it on, on the cover it says high output quad four... take cover off, plugs are underneath...
Under the engine top cover ( the piece that says Quad 4 or some thing like that)
