How to Replace the Coolant in a Haima S5?
3 Answers
The method for replacing the coolant in a Haima S5 is as follows: 1. Unscrew the radiator cap to drain the coolant; 2. Start the engine and let it idle, then inject clean water until the water coming out of the radiator is clear; 3. Once the clean water has drained completely, close the water valve; 4. Add new coolant until the liquid level is between the MAX and MIN marks; 5. Close the cap and let the engine idle for two to three minutes. The Haima S5 is a compact SUV under the Haima brand, featuring a MacPherson strut front suspension and a multi-link independent rear suspension. In terms of body dimensions, the vehicle measures 4418mm in length, 1823mm in width, and 1630mm in height, with a wheelbase of 2630mm.
I've changed the antifreeze for my Haima S5 several times by myself. The engine must be completely cooled down—don't rush it, or you might get badly scalded. Open the hood and locate the round coolant reservoir cap, usually made of plastic, and slowly unscrew it on the right side. Place an oil drain pan beneath the drain valve or lower hose outlet to carefully drain the old antifreeze. It's advisable to flush the system before refilling to prevent old residue from clogging it—use water or new fluid to rinse thoroughly, but avoid mixing different types. Then pour in the new antifreeze; Haima S5 recommends ethylene glycol-based antifreeze, matching the blue-green color, and fill it up to the MAX line. Start the engine for about ten minutes to let the fluid circulate, then check if the level has dropped or if there's any air leakage. The whole process takes roughly half an hour—wear rubber gloves and goggles since antifreeze is highly corrosive. Regular replacement protects the engine, saving money and ensuring peace of mind.
Be cautious when replacing coolant. After the Haima S5 engine cools down completely, first open the radiator cap to confirm pressure release. Connect the tools to drain the old fluid, and locate the drain hole for operation. Proper disposal of old coolant is crucial—never pour it down the drain to avoid environmental pollution. Choose a compatible new coolant, check the label to ensure the ethylene glycol concentration meets standards, and a 4-liter container is recommended for a full refill. After filling, start the vehicle to raise the temperature; fan operation indicates normal system function. Then turn off the engine and recheck the fluid level, topping up to the standard mark. Use a multimeter during the process to verify circuit stability and prevent overheating-related failures. Remember, mixing coolants can cause corrosion—prioritize safety throughout and operate in a well-ventilated area. Regular maintenance reduces major repair risks, offering multiple benefits.
