What is the installation method for a car preheater?

Below is the installation method for a car preheater: 1. First, determine the fixed position of the preheater, ensuring it is at least 20-40 cm lower than the water tank cap. 2. Identify the series connection positions: the engine drain hole, the heater hose, and the small circulation pipe. 3. Select and confirm the installation method, then cut the heater hose. 4. Connect the preheater's water inlet to the lower cut hose and tighten it securely. 5. Slowly add antifreeze until it flows out from the preheater's water outlet. 6. Connect the preheater's water outlet to the cut hose and tighten the hose securely. 7. Fill the antifreeze to the standard level and check for any leaks. 8. Start the car engine to completely expel air from the pipes, then top up the antifreeze to the standard level. 9. Connect to a 220V power supply for testing. The power indicator light will be red, and the working light will be green. Both lights will turn on simultaneously when the power is connected. The preheater will vibrate slightly, and the heating chamber housing will become slightly warm. When the engine reaches the starting temperature of 40-50 degrees, the green light will turn off, indicating the preheating is complete.
A few days ago, I installed a preheater by myself, and the process was simpler than expected. First, determine the installation location, usually near the battery or behind the firewall, avoiding moving parts like pulleys. Prepare the water hoses and power cable accessories, cut a section of the engine coolant pipe, and connect the preheater's inlet and outlet hoses, making sure not to reverse the arrow directions. The power cable should be directly connected to the battery's positive and negative terminals, with a fuse added for circuit protection. Use self-tapping screws with anti-vibration washers for securing to prevent loosening due to road vibrations. Finally, start the vehicle to check for any water or electrical leaks, and test the preheater once when the engine is cold. The whole DIY installation takes about two hours, and it's quite cost-effective if you're handy.
