Simple sounds that need checking out before they turn into something serious
1. GurglingDoes your motor sound like Homer Simpson’s guts after a night on the Duff? Time for a look at your cooling system. Coolant should circulate silently. Firstly, check the level, any drop indicates an issue. If there’s an air pocket, the pump won’t be able to circulate coolant properly, and it can froth around and boil if it can’t circulate away from hot spots. Top it up – if it drops again you may have a leaking seal or gasket. Bubbling coolant, or coolant being forced into the header tank too readily, may indicate a blown head gasket or another overheating problem that needs investigation.
