Vehicle Overheating and High Temperature Gauge The primary role that coolant plays in your vehicle’s functioning is keeping your engine temperatures low. If you find that your temperature gauge is always high and your engine is frequently overheating, chances are that you need a coolant flush.

Why is my car losing coolant but not overheating?

If you’re leaking antifreeze but not overheating or you have a car leaking antifreeze when parked, you still have a chance to repair your vehicle for a lower cost. Chances are you have either a radiator cap leak, internal coolant leak or an external coolant leak. …

How long after adding coolant can I drive?

“Your personal safety is most important,” he says. “Waiting for at least 15 minutes allows the hood, engine and leaking coolant to cool.”

Is it normal for coolant to get low?

There are only two ways that the coolant in your car gets low. There is a leak, either in the radiator, the hoses, or the engine.

Why is my coolant draining so fast?

This can be caused by a number of things such as low coolant levels, a faulty thermostat, a clogged radiator or a failing coolant fan switch. … In addition to leaking around the pump, you may have a leak elsewhere in the cooling system coming from one of the hoses going to or from the radiator.
