Q: No radiator drain plug in a Suzuki

That’s because they don’t have them. They were cheaply made vehicles. Just as easy--you can take off the bottom radiator hose and do it when it’s cold so you don’t scold yourself. Make sure that it sat over night and it’s cool. You can just undo the fastener on the bottom of the radiator, pull the radiator hose and drain it that way. You are looking for something that doesn’t exist. If you’d like a professional to flush your radiator fluid for you, a technician from YourMechanic can come to your home to perform this service so that you can sit back and relax.
