6/24/2023 0 Comments Evans coolant cleans system![]() I will post my results here, good or bad. But, you MUST have PRESSURE with water based coolants.Īfter looking at all these things in more depth than I have posted here, I decided to try Evans coolant. You MUST have pressure with ANY water based coolant to increase the boiling point. A 4 core radiator is even less efficient. 2 cores of 1.5 inch diameter is better than 3 cores of 1 inch diameter. You can call any quality radiator manufacturer and they will tell you the same thing. The third thing is the number and size of cores. You need as much cooling AREA as you can get. ![]() Here is a bit of what I found.įlow is EVERYTHING. There is so much outright BULLSHIT about cooling out there, that I FORCED myself to do some study. Then, in the last issue of the rag that ebooger writes for, someone from Evans wrote to ebooger, and rather than address Evans in a professional journalist way, he was a snarky jackass. I lost what little respect for ebooger I had. But what is even more appalling than not testing a product and bashing the product, is jumping on the web, and using a COMPETITORS testing, without checking on the COMPETITORS work! Pay attention to who is FUNDING the article. If for sure it's actually true, that's not good. One increase is immediate from higher head temps, and the other is a buildup over time but both eventually requiring higher octane fuel. I saw a 4-5 point increase in required octane rating simply because of the two traits of the Evans coolants. This means one of the reasons people use aluminum heads (for lower octane usage without preignition) is pointless, as when the head temps get higher preignition becomes a problem even with aluminum heads. NUMBER TWO, is that with Evans coolant "iron and aluminum" cylinder head temperatures are higher by about 140 degrees. If used with aluminum heads that buildup on the surfaces causes the heat transfer from the head to the coolant to drop dramatically over time causing hot spots that make steam bubbles in the engine and therefore can cause crystallization of the aluminum. NUMBER ONE, is that the chemicals in the Evans products sticks to and builds up on aluminum parts and this wouldn't be too big of a deal unless you have aluminum heads. With Evans Coolant in your vehicle, you will no longer need to worry about corrosion, overheating or changing the coolant for as long as you have your ride.At first glance the Evans products look pretty nice although somewhat expensive for coolant, but a real high boiling temp and no pressure in the cooling system from expansion like other coolants sounded pretty tempting.īUT, after looking into it farther and some online research I found 2 major issue's with it. Not exactly surprising, since proper cooling maintenance is one of the most neglected areas of most cars. ![]() ![]() Reported findings of the U.S Department of Transportation, which states that cooling system failures are the leading cause of mechanical breakdowns on the highway. ![]() You also need to change the coolant before it degrades to the point where it doesn't perform its job adequately. The coolant must also have the correct mixture and chemical compounds to promote heat transfer, protect against freezing, and also inhibit corrosion. The reason for this is that old, exhausted coolant can actually cause irreversible damage to your engine components.Ī properly maintained cooling system must have a few things in order: adequate supply of coolant, a radiator that acts as a heat exchanger with the outside air, a fan or air flow source, a water pump to keep the coolant circulating, and a thermostat to regulate the engine at its optimum operating temperature. In general, Porsche recommends that you flush and clean out your cooling system once every 36 months, or approximately every three years. One often neglected task on many cars is the maintenance of the cooling system. The cooling system is one of the most neglected parts of a vehicle ![]()
