The time cover protects the timing mechanism and has oil/coolant passages. If damaged, it should be replaced to protect against leaks and also entry the debris.

You are watching: Where is the timing cover located


*

Step 1: Jack up the car. Make sure the automobile is in park, or in very first gear if it is a manual. Collection the brake and also put wheel chocks under the behind wheels. Jack the front of the car and also place it on great jack stands.

*

Step 2: drain the coolant. If your auto uses a time belt, there might be no require to drainpipe the coolant. But most cars operation coolant v the timing cover, so that will have to be drained before the cover is removed.

Remove the radiator or coolant reservoir cap, situate the drains with your workshop manual and let the coolant out into your drain pan. If your vehicle doesn’t have a drain, friend may have to loosen a water tap at a low spot on the engine.

*

Step 3: remove the radiator. No all cars call for radiator removal. If her is a front wheel drive car with a transverse (sideways) engine, it virtually certainly walk not. If your auto is a front-engine rear-drive, however, the radiator probably has to come out. There room a couple of exceptions whereby there is enough room to job-related with the radiator in place.

Remove the hose clamps and disconnect the hoses. If your car has an automatically transmission, disconnect the oil cooler lines as well. Unbolt the mounts and also remove the radiator.

*

Step 4: remove the drive belt(s). Your vehicle will have one or more drive belts that have to come off. It might be a question of loosening the mount on one alternator or other accessory, or if it is a late design car, that will have actually a spring-loaded tensioner the you have to loosen.

These are often daunting to reach and having the proper belt tensioner device will do all the difference. As soon as the belt is loosened, it might still be necessary to revolve the engine with a wrench while friend “walk” the belt turn off of the pulley.

*

Step 5: eliminate the water pump. On most timing chain cars and many timing belt cars, the water pump has to come turn off to get access to every one of the bolts or come get enough clearance to acquire the sheathe off. Remove the bolts holding that down and also gently pry it off.

*

Step 6: eliminate the drive pulley. Top top the former of the engine is a big pulley or harmonic balancer the comes through the timing cover. Obtaining the bolt off this pulley can be a an obstacle because the engine make the efforts to rotate while you attempt to loosen the bolt. You will have to use a crankshaft holding tool or an impact wrench to take it this bolt out.

Once the facility bolt is out, you should have the ability to pull the sheave off the crankshaft with little more than a couple of strikes top top the side from a dead punch hammer. If the is stubborn, a equipment puller or harmonic balancer puller will execute the trick. Watch very closely for any loosened keys that may slide out through it.

*

Step 7: eliminate accessories. The strength steering, wait conditioning, and/or alternator every may need to be eliminated to obtain complete access to the timing cover. In part cases, it can only be vital to eliminate a pulley-block from the accessory.

Study the workshop hand-operated and try to imagine pulling the cover 6 inches right off the the automobile to check out what might be in the way.

Part 2 the 3: remove the time cover

*

Step 1: remove the valve cover. This is another operation that might not apply to every cars. If your car has an overhead camshaft, it will certainly be important to take the valve cover off to accessibility the upper component of the time cover. If your vehicle has the camshaft in the block, the will most likely not be necessary.

Remove the crankcase vent hose and spark plug connections. Unbolt the cover and also work that loose. A few strikes from the dead blow hammer might be vital to get it started.

*

Step 2: remove the time cover bolts. Most timing covers have a variety of bolt sizes and lengths holding them on. It’s crucial to keep track of them. If you put a long bolt in a short hole and try to tighten that up, you have the right to do serious damage, and some that the bolt lengths just differ by a couple of millimeters.

The best way to save track of them is to attract a chart of the timing cover ~ above a piece of cardboard and also push the bolts into the cardboard as you remove them.

Some engines will have a few bolts comes up through the oil sump and also down v the cylinder head to the time cover. Be sure not come overlook these.

*

Step 3: remove the time cover. If your automobile has the cam in the block, usage your tiny pry bar or a huge screwdriver to gain purchase under the timing cover and also work it turn off the block.

If your auto has one overhead camshaft, there may be a portion of the time cover that fits increase under the cylinder head. Be very careful no to damages the head gasket at this point.

Some overhead camer engines have a two piece timing cover. There room a couple of more bolts, but this renders replacing the gasket easier. Eliminate the upper component of the timing cover before the lower part.

*

Step 4: inspect the time cover. Clean the time cover thoroughly and check the time cover for cracks or chips. Look closely at the machined surface ar where the gaskets attach. If you’re trying to fix a leak, it might be solved simply by instead of the gaskets and seals.

Part 3 the 3: installation the new timing cover

*

Step 1: install the new gaskets and also seals. Press the new seal into the timing cover and also tap it through the dead blow hammer till it is flush through the surface ar of the cover. Use RTV gasket sealer come the surface ar of the engine and also timing cover wherein the gasket mounts and stick the gasket come the engine or the timing cover.

If there space dowel pins in the block or the timing cover, rod the gasket on the surface ar that has the dowel pins.

*

Step 2: download the time cover. Installing the cover on the engine have the right to be the trickiest part of the job. The cover may need to slide across a pan gasket on the bottom or a head gasket at the top prior to it meets the surface of the engine.

A small dab that RTV sealer in the corners, where one gasket meets another, deserve to be beneficial for avoiding leaks. Insanity the covering in ar with the dead punch hammer come be certain it is steady seated.

*

Step 3: install the bolts. Refer to your diagram and screw the bolts into their appropriate location. Don’t tighten them best away. Once you tighten the bolts, occupational alternately across the cover for this reason the whole surface that the cover tightens evenly.

Tighten any bolts that go with the head or the pan last. If the engine has an upper and lower cover, tighten the lower cover first.

*

Step 4: download the front wheel or harmonic balancer. Install the pulley and tighten the bolt to the specification in the manual. This is very important since the after-effects of having the bolt loosen up if driving have the right to be serious.

Using a crankshaft hold tool and also a torque wrench, monitor the indict in the manual. The torque worth for the front bolt will be high, probably roughly 180 ft lbs.

*

Step 5: Reinstall the water pump, belts, and also other accessories. If the water pump is old, the a good idea to change it now. It’s fairly inexpensive and also will ultimately fail, therefore you deserve to save yourself some trouble later.

Likewise, it’s an excellent practice come install new belts currently since you currently have them all off. Use a little RTV sealer on the new water pump gasket once you placed it on.

*

Step 6: Reinstall the radiator and also fill the cooling system. If there is a coolant bleeder, open it up. If not, eliminate a heater water tap at a high spot on the engine. If the coolant you drained the end is an ext than two years old, you have to replace it v fresh coolant.

Pour the coolant in through the reservoir. Keep putting until coolant runs the end of the bleeder or the hose the you disconnected. Close the bleeder and reconnect the hose.

Set the heater top top high, and also run the auto until you feel warmth coming the end of the vents. Proceed topping off the reservoir if the engine is warming up. When the automobile is completely warmed up and the coolant is at the exactly level, download the press cap on the reservoir.

Check the engine because that oil or coolant leaks, then take it turn off the jack stands and also take it out for a drive. Examine again for leaks after driving about for a couple of minutes.
