How to Clean a Vehicle Radiator?
2 Answers
Vehicle radiator cleaning method: 1. Wait for the coolant temperature to drop, open the expansion tank and add rust remover cleaner to the radiator; 2. Start the engine and let it idle for 5 to 10 minutes after the cooling fan operates; 3. Turn off the engine and remove the front bumper of the vehicle; 4. Ensure the coolant has completely cooled, then drain the radiator rust remover cleaner along with the coolant, and replace it with new engine coolant. The function of the car radiator is to dissipate excess and unnecessary heat from the engine, ensuring the engine operates at normal temperature under various speeds or driving conditions.
When I cleaned the radiator myself last time, I found it actually quite simple, but it has to be done step by step. First, find a safe place to park and wait for the engine to cool down completely, otherwise, getting scalded by hot water is no joke. Then, open the radiator cap and drain the old coolant with a special wrench—remember to catch it in a bucket. Add a radiator cleaner, the kind that removes rust, and let it circulate for about ten minutes, following the instructions. When rinsing, use a hose to flush water through the filler neck, repeating several times until the water runs clear. After using this method myself, the engine temperature was better controlled, and there were no more fluctuations. Key points: Don’t misuse tools to avoid damaging the pipes, and don’t forget to add new antifreeze at the end, or all the effort will be wasted. Doing this regularly can save a lot on repair costs.
