Evans Waterless Coolant Aviation: A Solution for Cooling Problems in Large Engines

Large engines, such as those found in aircraft like the Caddy 500, can be prone to cooling issues when towing heavy loads or operating in hot temperatures. One solution that has been successful in addressing these problems is Evans waterless coolant, a proprietary product designed specifically for aviation use.

In my experience, I have run Evans in my Caddy 500 for years, and it has consistently performed well even under demanding conditions. The secret to its effectiveness lies in its unique composition, which allows it to flow freely through the engine's cooling system without the risk of boiling or vapor lock.

One common issue that can arise with traditional coolants is air trapping in the heads, which can cause hot spots and reduce thermal efficiency. To combat this problem, I recommend using an infrared heat gun to identify hotter areas on the head surfaces and comparing exhaust header temps to pinpoint any issues. By addressing these problems early on, you can prevent more serious damage from occurring.

Another solution that has been shown to be effective is drilling additional coolant holes in the deck of the block at the rear. This allows for increased flow through the system and helps to dissipate heat more effectively.

In addition to using Evans waterless coolant, I also recommend backing off the timing by a degree or two to see if it improves cooling performance. Some radiators can be modified to use multiple passes, which can also help to increase cooling efficiency.

It's worth noting that many large engines, including those with superchargers, are able to run safely and efficiently using Evans waterless coolant. This product has been specifically designed for aviation use and is available in a range of formulations to suit different engine types and operating conditions.

In conclusion, Evans waterless coolant is a reliable solution for cooling problems in large engines like the Caddy 500. By addressing air trapping issues, increasing flow through the system, and using a high-performance coolant, you can ensure that your engine operates safely and efficiently even under demanding conditions.
