Drainage problem of Santana 3000 water tank

Go to the garage or elevator in the sewer. 3000 water is plugged at the bottom of the water tank. Unscrew it. Be careful when it is a plastic plug. If you can't find the water plug, open the sewer pipe with carp pliers or screwdriver. There are two water pipes in the water tank for drainage, and then there is a * 14 screw under the engine exhaust branch pipe. That's the drain screw on the cylinder block to drain water (Santana 3000 doesn't know if there is such a drain screw, I haven't touched this car). Then start filling antifreeze. After filling it up, hold the water pipe by hand. Then start the car, and the antifreeze will sink a little before filling it up. After turning on the electronic fan, screw on the water tank cover and wait for the temperature to drop. When the electronic fan is turned off, it will be OK. Santana 3000 is automatic and does not need to exhaust. I hope I can help you.
