#2059 - Antifreeze Tips, Hybrid vs. EVs & Cold-Weather Car Care

Antifreeze does much more than prevent your engine from freezing. It removes excess heat to help prevent overheating during warm weather and contains corrosion inhibitors that protect cooling system components. Maintaining the proper coolant mixture helps keep your engine running efficiently throughout the year.

PEAK recommends checking your coolant level at least once a month and before long road trips. Always check it when the engine is cool. Look at the coolant reservoir and make sure the fluid is between the marked minimum and maximum levels.

Concentrated antifreeze must be mixed with the proper amount of distilled water before use. A 50/50 premixed coolant already contains equal parts antifreeze and water, making it convenient for topping off your cooling system. The premixed option is especially useful for drivers who want a ready-to-use product.

Some antifreeze formulas can be mixed, while others should not be combined. Coolant colors can indicate different chemical technologies, so color alone is not enough to determine compatibility. Always consult your owner's manual for the correct coolant specifications.

Common warning signs include visible coolant leaks, cracked radiator hoses, and a sweet smell coming from the engine compartment. That sweet odor can occur when leaking antifreeze contacts hot engine components. Address coolant leaks promptly to help protect your engine and prevent pets from coming into contact with the fluid.

The best choice depends on your driving habits, access to charging, and transportation needs. Hybrids can offer improved fuel economy without requiring external charging, while electric vehicles may work well for drivers with convenient home charging. The C&C Auto Show crew recommends considering your lifestyle and total ownership costs before making a decision.

Cold temperatures reduce a battery's available cranking power. A battery that seems adequate during summer may struggle when temperatures drop, especially if it was already testing marginal. Having your battery checked before colder weather arrives can help you avoid unexpected starting problems.

Newer diagnostic scan tools can perform functions such as activating vehicle components, displaying sensor locations, and providing detailed diagnostic information. Some tools also offer vehicle inspection features that identify visible damage. These capabilities can help technicians troubleshoot problems more efficiently, and increasingly affordable tools are making advanced diagnostics more accessible.

If floodwater reaches an engine's air intake, water can be drawn into the engine. Unlike air, water does not compress, which can cause severe internal damage, including broken connecting rods. The show explains how differences in vehicle ground clearance and air intake height can affect the risk of water entering the engine.

Proper storage includes cleaning the vehicle, performing needed oil changes, and adding an appropriate fuel stabilizer. A battery maintainer can also help when a vehicle will sit unused for several weeks. Taking these precautions can reduce starting problems, fuel-related issues, and unnecessary repairs when you're ready to ride again.
