Next, turn on the heater to its maximum setting. This may seem counterintuitive, especially on a hot day, but it will help dissipate the heat from the engine. The heater works by drawing heat away from the engine and blowing it into the passenger compartment.

If you’re driving in stop-and-go traffic and can’t pull over immediately, turning off the air conditioner and turning on the heater may not be enough to prevent the engine from overheating. In this case, try putting the car in neutral or park and revving the engine a few times to get the coolant flowing.

How Long Should You Wait Before Driving a Coolant-Refilled Car?

If you’ve recently added coolant to your car’s radiator, it’s important to wait before driving. Coolant helps to regulate your engine’s temperature, and if it’s not at the right level, your engine could overheat. It’s important to let the engine cool down and give the coolant time to circulate before driving your car.

Most experts recommend waiting at least 30 minutes to an hour before driving your car after adding coolant. This gives the engine enough time to cool down and the coolant enough time to circulate throughout the system.

However, if you’ve added a significant amount of coolant, or if the engine was very hot when you added it, you may want to wait a bit longer. Temperature is the key factor here – you want to make sure the engine is at a safe operating temperature before hitting the road.

It’s also important to note that adding coolant does not fix the underlying problem of why your coolant level was low in the first place. If you’ve had to add coolant, it’s a good idea to have your car inspected by a mechanic to determine if there are any leaks or other issues causing the low coolant level.

Wait Until the Engine Cools Down

Patience is key when it comes to refilling the coolant and driving your car. You need to wait until the engine cools down before you can drive it. Depending on how hot the engine is, this could take anywhere from 30 minutes to an hour.

Don’t rush it – driving your car with a hot engine can cause serious damage and potentially cost you thousands of dollars in repairs. It’s not worth the risk to your car or your safety.

Be mindful of the weather – if it’s a hot day, it may take longer for the engine to cool down. In this case, it’s best to wait until the temperature drops in the evening or early morning.

Check the coolant level – once the engine has cooled down, check the coolant level again. If it’s low, you’ll need to add more coolant and wait for the engine to cool down once again before driving.

Take it slow – even after the engine has cooled down and you’ve refilled the coolant, take it slow and easy when you first start driving. Keep an eye on the temperature gauge and watch for any warning signs that the engine is overheating again.
