Is Evans Waterless Coolant Right for My Classic Car?

Posted on

For many, classic cars are our true pride and joy. We put countless hours into restoration, preservation, and detailing, but no matter how much work you put in, time is the strongest test, and the battle to preserve these classics is always ongoing. At Evans, we receive countless inquiries about our waterless coolant products and whether they are right for your classic cars. 

We’ve sorted through frequently asked questions and put together some information to help you determine if Evans Waterless Coolant is right for your classic car. Don’t forget, you can always call our tech team to talk about your specific vehicle. 

 Which cars are ideal for Evans coolant?

Systems that are clean and free of leaks with OEM type stock engines and OEM radiators. A dirty system that has been running since 1950 will need to be cleaned with system flush before being converted to waterless coolant.

Advantages of Evans Waterless Coolant for Classic Cars

Storage 

Evans does not freeze and expand in the way that water does. If your car has long periods of inactivity during the winter months, waterless coolant will help protect against damage caused by solidifying solutions. (For long-term storage, the system should be filled to the top and sealed to prevent the coolant from coming into contact with air.)

Engine Corrosion

Water-based coolants need to be changed periodically due to inhibitors falling out of your solution. Evans Waterless Coolant eliminates the water, thus blending the inhibitors directly into the coolant. This allows for maximum protection against engine corrosion throughout the life of the coolant.

Protection from Overheating

Without water to boil, Evans Waterless Coolant can run at a higher temperature without creating steam and boiling out of the system. This prevents engine metal temperatures from ever exceeding a critical limit.

Disadvantages of Evans Waterless Coolant for Classic Rides

Operating Temperature

Each vehicle is different, and in some cases where the goal is to lower operating temperatures, Evans may not be the right solution. For questions involving operating temp, we suggest giving our tech line a call at 888.990.2665to discuss your specific car and issues. 

Leaking Components 

If your vehicle is already experiencing leakage prior to conversion, our product can make those leaks worse. Evans lowers surface tension, thus exposing any imperfections. If your vehicle experiences a leak, any dry stop leak product works, but we suggest part # HDC from Bars Leak.

What should I know about waterless coolant before installation?

  1. Evans Waterless Coolant does not claim to lower the operating temperature of your classic car. It will run at approximately the same temperature or slightly higher depending on your system components.
  2. If you are already experiencing leaks, Evans can make those leaks worse.
  3. Understand and locate your block drains before purchasing Evans Waterless Coolant.
  4. To reap the full benefits ofEvansWaterless Coolant, it cannot be mixed with any additional additives. In the case of an emergency, you can add traditional 50/50 coolant to the mix to reach the nearest service station, but you will then need to drain, flush, and refill your system. 
  5. Know the total cooling system capacity of the application.

Are paper/leather seals OK with Evans?  

Leather seals and paper gaskets are meant to work with water. When Evans Coolant is used, the paper should be sealed with silicone sealer (RTV) on the sealing surface and the edge or be replaced with a modern gasket. Leather seals should be replaced with a modern seal whenever possible to prevent any potential leaks.

Before Evans, many classic car drivers have struggled with the negative effects of traditional water-based coolant. Evans products prevent water-based damage while increasing reliability and engine life. To discuss your vehicle specifically, call our tech line at 888.990.2665.
