the car is a 4cyl. i think its a 2.2How to change a head gasket on a 1996 chevy corsica? step by step?This is the best site I could find.
%26quot;You have to start by draining the coolant from the radiator into a container as you can reuse it. And then you have to disconnect the positive terminal of the battery. After that you have to remove the serpentine belt.
Follow the following steps:
1, Remove alternator and brackets from engine. DO NOT DISCONNECT THE WIRES. Place alternator out of the way.
2, Unbolt and remove the power steering pump. DO NOT REMOVE THE HIGH PRESSURE LINES. Place Power steering pump out of the way. Remove Intake manifold to power steering support bracket.
3, Disconnect Tv cable and throttle cable from throttle body (ie the carburator)
4, Remove valve cover and disconnect all vaccum and sensor lines from the top of engine that may be attached to the head or intake manifold.
5, Loosen all rocker arm nuts and remove the pushrods from the engine. KEEP THE PUSHRODS IN THE ORDER THAT YOU REMOVED THEM.
6, Starting with the outside bolts loosen all the head bolts but do not remove them
UNDER THE CAR:
1, Unbolt the exhaust pipe to exhaust manifold bolts. Seperate and support the Exhaust.
FINAL STEP: Remove all the head bolts and remove the head from the car.
From there you Should be able to figure it all out. %26quot;How to change a head gasket on a 1996 chevy corsica? step by step??How to change a head gasket on a 1996 chevy corsica? step by step?Step by Step
Replacing a head gasket is not a DIY job, unless you have plenty of experience, knowledge, and the proper tools. The fact that you would even ask, %26quot;How to replace a head gasket%26quot;, would indicate to some that you should not be trying to do that repair.
To replace a head gasket you must remove the intake manifold, exhaust manifold, valve train, and then the head. This is very involved and requires disconnecting lots of sensors and the ignition system. The head must then be checked to see if it is warped, or cracked, and repaired if necessary. You must then know how to put all this back together and torque all the bolts in the proper sequence. This takes training and skill which the average shade tree mechanic does not have.
There is a difference between say a over head cam (OHC) engine and a internal cam engine. And then if it is a V6 or V8 then both head gaskets must be replaced even if only one blew. And last but not least, you have to find out if there is other engine damage and what caused it to blow the gasket in the first place. Definitely not for an amateur.
The best answer to this question: Take it to a professional.
The second-best answer: Get a repair manual and follow directions. A repair manual does not provide the training necessary to do this repair correctly, and not near enough information, but it can provide more info than can be written out in an answer like this.
Below is the best answer we can provide in this format.
Exhaust flange nuts and bolts
Head Gasket (preferably OEM)
Ten head bolts
Two valve cover end seals
Tube of RTV silicone
1. Disconnect the battery negative terminal
2. Drain the cooling system
3. Raise the front of the vehicle and support it with jack stands .
4. Remove the two 13mm exhaust bolts holding the exhaust pipe to the exhaust manifold, lower the vehicle
5. Remove the air cleaner assembly
6. Remove the upper radiator hose
7. Loosen the 13mm nut holding the dipstick tube bracket to the thermostat housing and remove the coil (if it is attached to the thermostat housing) and unplug the coolant temperature sensor
8. Remove the spark plug wires from the plugs, remove the distributor water shield and the distributor cap (this step is so you don't damage the distributor cap).
9. Remove the two uppermost 15mm-head bolts from the top of the a/c , alternator bracket where it attaches to the head and unplug the single wire temperature sending unit
10. Remove the upper half of the timing belt cover
11. Remove the valve cover
12. Disconnect the wiring harness connector that is just to the right of the throttle body
13. Disconnect the throttle cables from the throttle body and remove the two 10mm head bolts holding the bracket
14. Disconnect the vacuum lines from the throttle body
15. Disconnect the fuel lines - NOTE : The fuel lines may be under pressure , use extreme care when removing them
16. Disconnect the throttle position sensor connector and the EGR valve connector (if equipped)
17. Carefully lift up the throttle body wiring harness , the fuel lines , and the vacuum lines together and use a bungee cord to hold them out of the way
18. Remove the ground strap that is attached to the intake manifold from the fire wall
19. Remove the 15mm-head bolt holding the battery ground cable to the engine
20. Disconnect the vacuum hose from the power brake booster and the heater hose from the intake manifold left side
21. Use two plastic tie straps to secure the timing belt to the camshaft pulley and remove the pulley . Hold upward tension on the pulley and secure it with a bungee cord to the right hood hinge - NOTE: be sure to hold the upward tension with the bungee cord so the timing belt doesn't jump a tooth on the lower pulleys
22. Remove the head bolts and lift the head off the engine block . (I suggest having an assistant help to lift off the head) With the head removed , carefully check the head casting for signs of cracks. Also use a straight edge to check the head casting for warpage (maximum allowable warpage is .00
23. Clean all the head gasket mating surfaces and wipe clean with a little brake cleaner on a rag. Use a round plastic bristled brush to clean out the head bolt holes in the engine block and blow them out with compressed air .
1. After the gasket surfaces are prepared, set the new head gasket in place and CAREFULLY place the head into position, take extreme care not to place the head on the head gasket until it is in the proper position.
2. With the head in place, install the head bolts. You will need to tighten the head bolts in a circular pattern starting from the center and working your way out. I recommend hand tightening all the bolts before beginning the torque sequence. Head bolt torque: For older style 10mm head bolts : 35 - 45 - 45 - and a 1/4 turn; For newer style 11mm head bolts : 45 - 65 - 65 - and a 1/4 turn
3. Use the two rubber valve cover end seals and a bead of RTV silicone to reseal the valve cover.
4. Do Not let the silicone skin-over before setting the valve cover into place and tightening the bolts, also be sure that both mating surfaces of the valve cover are clean and oil free .
5. After the head is reassembled you will need to reset the base timing to specs. You will also want to double check the timing belt position . Use a variable timing light and set the timing mark on zero degrees . Save the setting on the timing light and shine it through the inspection hole in the top of the upper timing belt cover . If the belt timing is correct , you will see the oblong hole in the camshaft sprocket centered in the inspection hole .try this.... www.2carpros.com/makes/chevy/corsica.htm maby that can helpYou got to be kidding, step by step? Do what I did 30 years ago, they still make books, go and get one from auto zone and follow the direction. Assuming that you are mechanically inclined, it is not that hard. If you don't have torque wrench, you can rent one at A/Z also. Again it is not hard, just becareful to remember where everything go back to. Although, I don't think there is a mechanic that hasn't rebuilt an engine or two some time, and found a bolt or two left over. It wouldn't be right. What matters is where it is left off. LOL good luck. ITS NOT THAT HARD!
EDIT ... WOW, the women are showing me/us up... way to go girls!!!!
