If your car begins to overheat when idling, but the temperature gauge moves back down once you get going, it’s most likely due to a broken radiator fan. When the coolant goes to the radiator, it’s spread over a large surface area to cool it down. Airflow further cools it before it returns to the engine.
Coolant leaks from the water pump are common and a clear sign that it’s time to replace the pump. The coolant is stored inside the water pump using a series of gaskets and seals. Once these parts wear out, loosen, or crack, you’ll end up with radiator fluid leaking out of the front of your car toward the center.

Coolant Leak. The water pump has several gaskets that can be damaged or worn out over time.
Engine Overheating.
High Pitched, Harmonic Whining Noises.
Water Pump Rust and Corrosion.
Steam comes out from under your hood.
Holes or leakage system on the dry side of the water pump.

Odd Temperature Gauge Readings. Your temperature gauge should register cold when you first start your car and slowly build up to normal as the engine warms up.
It’s usually noticed if your coolant is low, but low oil can also cause the engine to overheat. This can occur even if your coolant level is fine. If there is too little oil in the engine, it will continue to heat up because it has no opportunity to cool.
Why is my car overheating when the coolant is full?
However, if your car is overheating, but the coolant is full, it is probably not a leak. Instead, it may be that it’s having trouble circulating correctly. This can stem from several things, including a faulty water pump, a radiator blockage, a stuck thermostat, or a plugged heater core.

What are 3 simple things to check if your car is overheating?
Steam (often looking like smoke) coming from the front of the vehicle under the hood. The engine temperature gauge in the dashboard or driver console spiking to “H” or moving into the red area of the gauge. Strange smells or odors emanating from the front of the car, particularly near the hood.
The furthest you can drive an overheating car is about a ¼ mile before you risk irreversible engine damage. While some vehicles could still make it as far as 20 miles, we would never recommend driving very far with an overheating engine.
What is the fastest way to cool down a car engine?
Put your car in neutral or park and then rev the engine. This makes the fan and the water pump work faster, which pulls more air and more water through your car’s radiator. This increased circulation cools down the engine. Pull over and open the hood.
Can I drive my car after it overheats?
If your car is overheating, you should definitely not drive it. This could be due to several factors, including low coolant levels or a faulty cooling system. Driving an overheated car puts additional strain on the engine, leading to further damage and costly repairs down the road.
Can I pour water on my engine to cool it down?
If your engine is still hot, don’t pour cold water on it. Pouring cold water on a hot engine can cause serious damage. Instead, let the engine cool down on its own or use a coolant to help speed up the process. Be sure to follow the instructions on the coolant container, as some coolants need to be diluted before use.
Can an engine survive overheating?
Most cars can only overheat for about 30 to 60 seconds before damage starts to occur. When a car overheats, it will quickly damage the engine. In only a minute, you may seize up your valves or even blow a piston if it gets hot enough. Of course, it does matter how hot the car is getting.
How do you tell if your engine is destroyed?
Is a car ruined if it overheats?
When an engine overheats, the pistons may expand so much that there simply isn’t enough room for them to expand anymore.This may cause them to scrape or scuff against the cylinders, damaging both in the process.
How much does it cost to fix a car that overheats?
The average cost to fix an overheating car varies, typically between $100 to $1,500. Since several components help cool your engine and car, you’ll need to find out what causes the problem to get a better idea of the cost.
