In the Red (Why a Vehicle Overheats)

December 21, 2025

Heat is one thing that can damage a vehicle, especially if a problem isn’t taken care of soon.  Be on the lookout for signs that it’s getting too hot in some parts of your vehicle, starting with the most obvious one: the heat gauge/warning light on your instrument panel.

When you see that heat gauge heading into the H zone or the warning light comes on, it’s often because your engine’s coolant is contaminated or running low.  It’s important to let a pro look at it soon before serious damage is done,

The radiator is another trouble spot that can cause overheating.  It has a fan that needs to run properly, and it needs to be free of debris and dirt. Another radiator trouble spot is the core.  When it gets clogged and coolant isn’t circulating as it should, an overheated engine can be the result. Have your cooling system checked regularly, including its thermostat.

Your water pump is another part of the cooling system that can wear out, and when it’s not working right, your engine can get hot quickly.  It should also be on the list of regularly checked engine components.

Finally, your vehicle has several rubber belts and hoses that play vital roles in making sure the coolant is getting where it needs to be.  It’s important to have those inspected by a technician before they fail and heat starts to build up.

Your vehicle’s cooling system is complex and critical to its operation. Plus, it must be maintained so it does what a vehicle’s engineers designed it to do.  When it comes to your vehicle, cool is cool, hot is not.
