Using this coolant hose kit is easy. First, make sure your engine is cool. Then, remove the old factory coolant hoses. You can directly bolt on this new silicone hose kit in place of the old ones. When installing, check that all connections are tight to prevent any coolant leaks. As for maintenance, it's a good idea to inspect the hoses regularly for any signs of wear or damage, like cracks or bulges. Also, keep an eye on the coolant level. If it seems to be dropping, there might be a leak. If you notice any issues, replace the hoses as soon as possible to avoid engine overheating and other problems.
