V6 engine replacement filter base, oil radiator pad, pulley kit
ViolaDelia 
14 3.0V6 engine, DIY replacement filter base, oil radiator gasket, and pulley kit. Last year, it was found that there was a slight oil leakage in the filter base of the machine, and it was ignored all the time. In order to prevent the mixing of oil and water, it was decided to deal with it earlier. Tuben has now run 120000 kilometers, because the filter base of the disassembly machine needs to disassemble the tensioner and the transmission wheel. The swing of the tensioner feels a bit large, and the belt is also aging. By the way, we will replace this set of things together. I also have to thank the moderator and all the friends of the E forum. My interest has made this rookie dare to fix the big run by himself. The tools and accessories for this maintenance (inquiry selected from the shops recommended by the moderator) are all purchased online.
Because I did not lift the equipment to remove the chassis guard to empty the coolant, so I emptied the coolant by the way of pumping coolant. It happened that the barrel of pump oil bought last time had a high temperature and leaked oil, so the store directly refunded the money and gave it to me (fortunately, I didn’t throw it away). It’s no problem to pump cold water. Disassemble the bucket and wash it thoroughly.
Open the coolant kettle and drain the kettle first, then remove the return pipe, draw the coolant from this return pipe (marked in red), draw about 4-5 liters, and pay attention to the coolant kettle lid open to form hydraulic circulation.
The closed interface is just right to be plugged in, and it can be pumped very quickly. I don’t know if it is possible to change the coolant like this.
I smoked more than 5 liters, and accidentally missed a little bit when I disconnected the joint.
Remove 2 intake ports
Take a picture of the winding structure of the belt
Press counterclockwise on the big bolt of the tensioner with a No. 17 socket wrench, and the belt will be loosened and removed.
Remove the wheel with an E12 sleeve (as shown in the picture), take a picture before removal, and refer to it during installation.
Remove the wheel with an E14 sleeve (shown in the small red circle)
Continue to use the No. 17 sleeve to hold the large bolt of the tensioner counterclockwise without using a thin iron bar (drill bit) to insert it into the tensioner and get stuck, as shown in the figure.
Remove the two fixing bolts of the tensioner with E14 sleeve, as shown in the red circle on the picture, remove the tensioner and see that there is oil seepage in the base.
Disassemble the fixing bolt of the thermostat with E10 sleeve, one of which is blocked by the air pump (shown in the red circle), first remove the four screws of the air pump fixing bracket, so that the air pump can be shifted and do not have to remove the air pump. I used a small flying sleeve to remove from the gap, the thermostat two screws, time and temperature response so that the thermostat gasket has been fused with the cylinder, with brute force absolutely can not break off Need to spray some rust remover, shake slowly, the thermostat interface is shiny and clean, and the coolant quality of the original car for more than 10 years is really good.
Remove the filter element of the oil filter and pay attention to cleaning up the oil
Begin to remove the bolts on the filter base of the machine, there are a total of 6 bolts, as shown in the picture, please pay attention to the length and length of the bolts and remember the fixed position of each screw. similarly, the filter base is also difficult to break, the rubber pad is “embroidered”, spray rust remover, shake, rust remover is really a good thing, it is best to cover the bolt on the filter base and remove it together, marking the specific position of each bolt.
This is the appearance of removing the base. The mat glue has aged for more than ten years at high and low temperatures. This common problem has to leak when it comes to time, so it is best to replace it when it comes to a certain time.
This is a machine filter. The pad is so hard that it has no sealing effect.
Get the radiator on the filter base of the disassembly machine on the thick paper shell. T30 sleeve has a total of five bolts, and there is also a cushion glue inside. Use the carburetor to clean the grease dirt on the base and the radiator. The radiator (left) must not be washed with water. Because there is oil in it, it is like a honeycomb network, and it is difficult to clean when the water goes in.
You can do it slowly by yourself, and it’s very difficult to remove the residual glue inside, because I didn’t use carburetor (worried about environmental protection). I sprayed it with carburetor, and I can clean it quickly with an iron brush. I didn’t know until I was brushing the residual glue on the cylinder.
Clean the oil dirt and cushion residue on the engine cylinder block, use a small iron brush, clean the fuel injector, and brush it quickly. The pad on the thermostat is very difficult to clean, and the oil outlet hole is blocked with a rag.
Key mention of these two cushion glue, because this can not be seen inside, rely on it to separate water and oil, I consulted several stores, there are several brands, Mahler, Erling, Dena, as well as the so-called original factory, the price difference is also big. When I asked a store for the original factory, he said that the original factory was also ordered outside (orange). He also guaranteed that it was the original factory, but now they officially ordered it in black. The price is more expensive, this he absolutely guarantees the original factory authentic, he thinks outside the orange color is not real, can use, but the service life is not long, think about the difference of 100 yuan finally I chose black, after receiving the goods to see the packaging and quality, there is no doubt about 4S store goods.
First install the radiator on the bottom seat, 5 screws torque 14, put the gasket glue into the groove installer filter base, bolt position corresponding, first small force tightening, and then use torque wrench to fight torque, torque value 20nm
Install the machine filter element
Install thermostat, replace gasket, bolt torque 25 nm, install new tensioner, stick clip on tightener, bolt torque 35 nm
Refer to the old photo to install two new transmission wheels, bolt torque 25 nm, my set of old parts do not have any abnormal sound, in fact, I can continue to use tens of thousands of kilometers, change early, I think the tensioner has a small swing is a normal phenomenon

Refer to the winding position photo taken in advance to install the belt, carefully check each position and the belt groove clamping position, press and hold the big bolt of the tensioner to remove the small iron bar, slowly loosen it, and the belt will be tightened.
Connect the coolant return pipe and add the extracted coolant to the pot, which may be full. There is still a little left. Leave it alone and cover the lid.
Once again, carefully check the belt installation position and maintenance parts, install the intake pipe, start the engine, observe the belt and transmission mechanism, listen to the sound is not abnormal, open the coolant kettle cover, if less continue to add coolant, observe the water temperature to about 70-80 degrees, immediately turn off the engine, if there is any surplus to continue to add the remaining coolant, how much to add
After drawing out all the coolant, continue to start the vehicle, pay attention to the water temperature, drive out for a test drive, continue to open the coolant kettle to observe, check the exhaust air, and finally perfect the end, and follow up to observe the water temperature.

This is the purchased accessory: Belt Kit Schaffler (INA). The price of Schaffler is very transparent, but it is possible to buy the same thing for double the price. In fact, the Schaffler is completely enough and easy to use. The original factory has 3 pads. I can only trust the store because I really don’t know.
This is a purchased tool. Some tools will be used when changing oil and spark plugs in the future
