About the engine
Car enthusiasts in many countries around the world are well aware of such a car as the Toyota Corolla A100; it was its power unit that was taken as the basis for the Geely MK. Manufacturers from China bought a license for the Toyota 5A-FE engine. It is characterized as a reliable, economical power unit, which, with proper, timely, high-quality maintenance, allows you to drive a million kilometers.
Subsequently, an engine of its own design was developed for the Geely MK MR479FQA. It is rightfully considered one of the best developments by Geely. The technical characteristics of this power unit are in no way inferior to the developments of other well-known engine manufacturers. Experts note its relatively low production cost, low noise level, and good maintainability.
The engine is an in-line design with four cylinders, two overhead camshafts. The valve mechanism requires periodic adjustment, which cannot be ignored. The head is made of aluminum alloy, the inlet and outlet channels are in opposite directions. The timing mechanism is driven by a belt drive, in which the belt requires replacement after some mileage.
Features of the gas distribution mechanism
A special feature of the gas distribution mechanism of this car is the presence of 16 valves, that is, 4 valves per cylinder. To put them into operation, two camshafts are installed in the head, which are driven into rotation by a toothed belt.
The camshafts are equipped with gears that are rotated by a belt. There are also tension and deflection rollers. The Geely timing belt also rotates the coolant pump.
The power unit is designed in such a way that it is difficult to reach the components of the gas distribution mechanism. When the timing belt breaks, the valves on this engine most often do not bend.
Installing a new timing belt
We install the timing belt tension roller in place, be sure to put on the spring, otherwise after installing the belt it will be very difficult to put it on. Do not tighten the bolt.
We check all the marks again and install a new timing belt in place. First we put it on the crankshaft sprocket, the camshaft sprocket and the tension roller, pulling it off with your finger. Make sure that the right side of the belt between the crankshaft and the camshaft is tensioned. Tighten the tension roller bolt. We install all the removed parts in the reverse order of removal.
Everything is very simple.
Good luck on the roads. No nail, no rod.
Replacement timing
Car manufacturers Geely MK recommend not exceeding 60 thousand km to replace the belt. However, there are cases when it fails much earlier. Experts recommend paying attention to the condition of the timing mechanism drive parts whenever servicing the power unit. If cracks are noticed in the belt cord, fabric peeling, or other damage, the belt must be replaced. Its accelerated wear is caused by technical fluids and motor oil entering the work area. If leaks are detected, they are repaired immediately. The operating conditions of the machine can also reduce the service life of the timing belt. In this regard, there have been cases of belt replacement at 30–40 thousand km.
How to set control marks on the timing belt
To set the control marks of the Geely SK gas distribution mechanism, you need to rotate the timing belt. This must be done using the crankshaft gear. It has a thread for a bolt that secures the crankshaft pulley. This bolt is what you need to turn the timing belt. You need to turn the timing belt strictly to the right, that is, from left to right. To make this task easier, you can engage 1st gear at the gearbox.
- We control the position of the crankshaft gear. There are markings on the wheel, these are the letters “L” and “F”, that is, “Left” and “Front”. The letters must be in a strictly horizontal plane. Additionally, the position of the crankshaft wheel can be controlled by the keyway. The groove should point straight up.
- We control the position of the camshaft gear. The reference point for the correct position is the letter “K”, which is on both sides. The pointer should point straight up. In this position, the letter “K” will coincide with the arrow-shaped mark that is engraved on the engine body.
If all the marks match, then you can remove the timing belt and carry out further engine repairs.

How to set timing marks in Geely SK
The gas distribution mechanism (GRM) is the most important functional system of any car. The timing belt includes critical Geely SK spare parts, which require timely maintenance and replacement every 40,000 - 60,000 (km) mileage.
With any intervention in the gas distribution mechanism of Geely SK, it is necessary to set the timing belt according to the marks. That is, the marks on the pulleys and gears must match the marks on the engine body.
The alignment of the control marks of the gas distribution mechanism indicates that the piston of the 4th cylinder is installed in the TDC (top dead center) position.
If the timing marks coincide on both the camshaft pulley and the crankshaft pulley, then the gas distribution mechanism is configured correctly. In this case, the stroke of fuel injection and exhaust gas removal will coincide with the rotation stroke of the crankshaft.
If the phases of the gas distribution mechanism are out of order, then the Geely SK engine may suffer serious damage: bending of valves, deformation of the camshaft and crankshafts, deformation of the piston group, destruction of the cylinder block, etc. In order to prevent the timing phases from being disrupted, it is necessary when dismantling and installing the timing belt control the correct position of the marks.

1.5 is not enough, they ask us for work 5 and don’t come closer.
I also picked up the timing belt from Emex today. But I won’t change it yet, I still have the factory one, I’ve already run 135 thousand.
The valve does not bend, of course, if the belt breaks, but according to the law of meanness, it breaks at the most inopportune moment. After 100k km, it’s better to update it and not play around with it.
who said that after 100 you need to change? At the factory, who did they put a yellow sticker with the inscription about replacing the belt after 120 thousand? The factory gives a guarantee of 120 thousand for the belt, so 120 is not the maximum service life, but with a reserve. So why pay more?! Yes, 95% of jilivods change in Ukraine at 60 thousand, in Russia I don’t know, but I think + - the same amount and all because they make money from the services. I can give examples when friends changed the factory belt and it broke after 50 thousand, because it was shitty, although it was from a brand name manufacturer and not cheap. Then they just took it and installed the factory one. It was after listening to them and seeing the sad experience that I did not change it, as they say in the services. I believed the factory sticker. Now it’s clear, it’s time, I bought it for sale, it’s lying there, waiting in the wings. Buy a couple more belts and a roller and go into battle).
I just read it and understand that I’m not driving a Geely, but a million-dollar Toyota) From my own experience, I’m convinced that the original is a pig in a poke, and if you install the right analogues, it goes an order of magnitude better.
Well, of course it’s a Toyota, I have a belt from a Toyota and there are stub drains from it and little things, don’t even think that it’s a Dzhilik, this is a Toyota, we’re not rogues, we’re cool, ahaha))) But seriously, I’m like I would like to share my experience, I actually got 135 thousand on the factory belt, I didn’t even bother until 120 thousand, after adjusting the valve, then I changed the gasket and at the same time monitored the condition of the belt. I notice that the MK until 2012 was, as you say, a pig in a poke, but the 2012 restyling is already a good and reliable car. I read an article a long time ago about how the Chinese fixed the bugs and indeed, everything works, unlike earlier versions.
I agree with you kol4in 123 100%, I just started to grunt in the box when it’s cold, but at 80t.km everything else is normal. I don’t count small things like light bulbs and consumable oil and filters.

Why, you need to swap it for a Toyota milliliter, but 3 liters and you’ll get a beast)))
It was changed 20-40 thousand ago, judging by the condition.
Poti is right, 30 thousand.
Well, I guessed it)))
how long did it take to replace? I also bought all the belts + a valve cover repair kit, I want to change it the other day
Well, we drank beer at the same time as the repairs, we did it in about 4 hours
Step-by-step instructions on how to set timing marks on a Geely SK car
To get to the timing marks, you must first expose it. The timing unit is hidden behind:
- Air preparation unit
- Valve cover
- Right engine mount
- Crankshaft pulley
- Timing protective cover
Additionally, on the way to the timing belt there is a generator and several belt drives that need to be removed. As is clear, before describing the control of timing marks, you need to tell how to get to the marks.
The Geely SK repair blog has several reviews on the topic of servicing the timing unit: how to replace the timing pulley and how to replace the timing belt. In the notes you can find detailed instructions for disassembling the timing belt specifically for this car. Only the main stages of this process will be described below.
Equipment and Tools Required for Belt Replacement
To change the timing belt with your own hands, you need to have an inspection hole, use a lift or elevation. If there is no lift, then at home you can use a jack to lift the car, which any motorist must have. If such a replacement has not been carried out independently before, it would be a good idea to arm yourself with a manual or look in advance on the Internet to see how the replacement procedure occurs.
To make equipment repairs faster, it is best to collect all the necessary tools in advance, which include:
- Wrenches of different sizes.
- Various heads with long handles.
- Equipment designed to control the tightening force of parts.
- Gear removal device.
- Screwdrivers are shaped like a tip.
- Insulation.
- Felt pen.
- Clean cloth.
- Other small consumables.
For the replacement to be successful, it is recommended to carry out the repair with an assistant. Better, this person has an idea of how to make repairs and replaced the belt himself.
