Question about Cars & Trucks
I was wondering will it be better to do a motor flush first before I start breaking down everything to get to the head gaskets on my 2003 Chevy Malibu or does it even matter.
I would think it would be better after you change the head gasket and drain the old oil from the system. Then check the new oil and depending of how much water you are seeing in the new oil you may want to flush the engine. I suspect it will not be necessary because the time it takes to change the head gasket will also allow for the excess water to drain to the oil pan.

That engine does not have a timing belt, it has a timing chain and therefore much easier to work with as it can only go on a certain way, the primary focus being getting the dots on the timing chain sprockets lined up properly.
I believe, with the engine at Top Dead Center on cylinder #1, the dots will be facing each other. That is to say, the do on the cam sprocket will be facing the dot on the crank sprocket.

Overheating could be a combo of many thing's.If your thermostat is stuck you will have no circulation which will cause overheating.Also if your eng. has alot of miles your water pump may be in need of replacement.Listen for your radiator fan motor and be sure that's working and also check to see if you radiator is good.If your loosing antifreeze because of a headgasket you will see a white cloud out of the exhuast because it is burning it and sometimes you also get a little in your eng.oil.Using a pressure tester on your coolant system will help to diognos the problem,if you have a leak some where it will not hold pressure.Sign,s of a bad waterpump are poor circulation and a antifreeze leak from a vent on the waterpump.Be sure the eng. is cool before working on it.Hope this was helpfull.

The first step is to remove all the parts that are in the way of you being able to remove the valve covers. (Ex.: air intake, loose wires etc.) Then you will need to remove your valve covers (using basic tools) and be very careful to not let anything get on your lifters, which your valve covers protect. Once you have the valve covers off compare the new gaskets to make sure they are the right size. Then remove the old gasket and replace with the new one using a high temp gasket sealant (available at any auto parts store) to attach the gasket to the valve covers. Then tighten down snug and check for leaks after replaced.

Well first you can please follow the below steps -
1. Make sure the ignition key is in the off position and the headlight switch is off. Release the hood latch.
2. Open the hood and locate the top of the headlight assembly where you intend to change the headlight. If a plastic shroud is present, locate the center bolt and remove it with a ratchet and a socket. Lift the shroud out of the way to access the headlight assembly retaining brackets. Some later models may feature a snap-release shroud requiring no tools to remove.
3. Locate the brackets on the top rear of each side of the headlight assembly. Lift them all the way up to align the hole on the bottom of each bracket to the retaining tabs on the assembly.
4. Pull the assembly forward away from the Malibu, but be careful not to scratch the bumper. There are three guide pins that require unseating. The guide pins are what aim the headlights and it may take some wiggling to get the pins from their seats.
5. Support the assembly with one hand and then reach behind the unit with the other. The low beam bulb is on the outside, the high beam bulb is on the inside. You can also replace the parking light if desired. Locate the wire harness connection. Un-clip the wire harness from the back of the bulb socket. Remove the bulb by turning it counterclockwise 1/3 of a turn to align the release tabs of the ring and the assembly. Wiggle the bulb out of the assembly.
6. Place the latex gloves on your hands before opening the package of the replacement bulb. Oil in our skin can damage the glass bulbs of halogen headlights.
7. Carefully insert the new bulb into the ring and then align the tabs of the ring to the tabs of the headlight assembly. Push inward and then twist clockwise 1/3 of a turn to lock the bulb in place. Reattach the wire harness. Rest the headlight assembly inside its cavity and test the operation of the headlight before securing the headlight assembly in place. Be sure to turn the lights and ignition back off.
8. Align the three guide pins to their seats and push the assembly back into them gently until they snap into place. Replace the retaining brackets by pushing them downward to lock into place. Replace shroud, if applicable. Remove the tools and old bulb and close the hood. Post comments for further help or information......
