Replacing the timing belt Opel Astra N Z16XER

Finally, an old friend of mine exchanged his rusty bucket for a normal car and immediately came to our sales post. So, we have an Opel Astra H 1.6 Z16XER replacing the timing belt, rollers, oil and filters.

Since this is an Opel, in addition to regular keys, we will also need Torx sockets, but they have long been in every tool kit. We will also make a clamp for variable valve timing clutches from an eight bolt and two washers. If this method seems unreliable to someone, you can buy clamps in any online store for only 950 rubles. Let’s make a reservation right away that if the car is equipped with a manual transmission, then there will be no difficulties, but if it’s a robot, then you will have to either make a crankshaft clamp or use a pneumatic impact wrench. We do not change the pump since it is driven by the alternator belt. It took an hour and a half and one mug of tea to replace the timing belt.

Actually, the patient himself.

Under the hood is a 1.6-liter engine called Z16XER.

First, disconnect the air filter with pipes from the throttle valve.

We remove the front right wheel, the side plastic protection and jack up the engine through a plank. We remove the generator belt, using a nineteen key, using a special protrusion, turn the tension roller, thereby loosening the belt. In the photo it has already been removed.

Remove the engine mount.

We dismantle the support.

Remove the upper protective cover of the timing belt.

Remove the middle part of the plastic protection.

Set the top dead center. We turn the crankshaft by the bolt, always clockwise, until the marks on the crankshaft pulley and the lower protection coincide. It's not very visible, but it won't be difficult to find them.

The marks on the top of the camshaft couplings should also match.

Unscrew the crankshaft pulley bolt. If the transmission is manual, then this procedure will not pose any special problems. We place stops under the wheels, turn on the fifth wheel, insert a specially trained screwdriver into the brake disc under the caliper and, with a slight movement of the hand, unscrew the bolt. But if the robot is like in our case, then a wrench helps us, but if there is no current one, we make a crankshaft pulley clamp. In the corner we drill two holes by eight and insert two bolts there, tightening them with nuts; we eventually insert these bolts into the holes in the pulley. You will get the dimensions yourself by measuring the distance between the holes. In the photo, the lock is shown schematically with a red rectangle; any holes can be used.

Remove the pulley and lower timing belt protection. On the left we see a tension roller, on the right a bypass roller.

We check the camshaft marks and, if they are gone, we bring them down. The marks on the crankshaft sprockets, in turn, should also match.

We install our Russian clamp on the camshafts and mark the old belt, just in case.

Using a hexagon, we turn the timing belt tension roller counterclockwise, thereby loosening the belt and removing the belt and rollers.

Let's start the installation.

We put the new rollers in place, and the tension roller has a protrusion on the body that should fit into the groove during installation.

Here in this groove.

We check all the marks again and install a new timing belt, first on the crankshaft sprocket, idler pulley, camshafts and pulling the tension roller onto it. Do not forget about the direction of rotation indicated on the belt. We remove our clamp.

We check the marks and, having replaced the lower protective cover and the crankshaft pulley, turn the engine two turns and check all the marks again. If everything matches, install all the remaining parts in the reverse order of removal. In principle, there is nothing complicated here, the main thing is to be attentive.

How to properly prepare for replacing rollers

Before replacing, place the car on a lift or inspection hole and allow the engine to cool for two to three hours. This is done to avoid burns, as well as to ensure correct belt tension. The fact is that when heated, the pulleys and rollers of the gas distributor expand in different proportions and move slightly in opposite directions. Even if you manage to properly tension the belt on a hot or warm engine, it will still sag after a couple of hours. Before the procedure itself, you need to remove the keys from the ignition and disconnect the negative terminal of the battery.

To replace timing rollers on an Opel Astra we will need:

Set of wrenches;
Set of heads;
Screwdrivers;
Shaft lock.

Causes of timing belt breakage in Opel Astra H

On XER series engines corresponding to the Opel Astra H, the pump is installed on the drive belt and is changed every 150 thousand km. On other models, it has the same maintenance schedule, similar to the belt; unfortunately, car enthusiasts often abuse the replacement of this part. And when the pump jams, a break also occurs.
Oil getting into the drive. Oil may squirt out through the valve cover gasket or camshaft seals. There is an option to prevent this by constantly inspecting the valve cover of the Astra engine for oil leaks. For which the design is intended, if they are detected, it will be necessary to replace the gasket and seals.

Step-by-step replacement instructions

Replacing the timing belt and rollers on an Opel Astra h looks like this:

Remove the engine compartment pan, the right front wheel, and jack up the engine;
Remove the air filter;
We unscrew the fastenings of the belt tensioner of the mounted units, and then remove the belt together with the tensioner;
We unscrew the mounting bolts of the timing case and remove it;
We set the camshaft marks. To do this, scroll the crankshaft pulleys clockwise until the marks on them are opposite each other;
We fix the pulleys in this position;
We dismantle the flywheel and lower timing case. Align the mark on the crankshaft pulley with the mark on the body;
Remove the engine mount and crankshaft sensor;
We unscrew the fastening bolts of the parasitic and tension rollers, and then remove them;
We pull off the timing belt;
If necessary, you can dismantle the pump. To do this, unscrew the four mounting bolts, having previously prepared a place to drain four liters of antifreeze;
We install new rollers and tighten the belt.

At this point, the replacement procedure can be considered complete, however, before you begin reassembling the engine, you need to check the belt tension and whether the marks are off. To check the tension, take a spring household scale and, hooking the hook onto the belt between the camshaft pulleys, pull the belt to the 10 kilogram mark. After this, we take a caliper and measure the deviation. A deviation of 5 - 5.5 mm is considered normal. Now that we have set the correct tension, we check the marks. To do this, you need to rotate the camshaft gears. If after two turns the marks match, then everything is in order and you can assemble the engine.

Consequences of a broken timing belt Opel Astra H

If the belt on an Opel Astra N breaks and oil leaks from under the valve cover, provided it has a pump installed, then an antifreeze leak is likely. On the Astra's dashboard, the oil pressure icons, the check mark, the machine with a wrench and the oil level sensor will light up.

If you suspect a break, you should not try to start a car with a manual transmission, pushing it, or holding it on a cable. When you try to start it with the key, the starter will spin and hum, but unfortunately nothing will happen. There is an option to tow the Astra to service in neutral gear, regardless of the gearbox.

When the Astra's timing belt breaks, the intake and exhaust valves hit the pistons and bend. Also, depending on the valve timing of the vehicle speed, there are variations in damage to the pistons and cylinder walls.
