![]() ![]() ![]() 15 years is a mind-blowingly long replacement cycle to me! That means barring a part failure (coolant hose crack, god-bless it a head gasket going), you're not going to replace the coolant. For your own use, make sure whatever you purchase (you cannot buy Khameleon on the market) meets the manufacturer's specifications. ![]() That was in a professional/multi-brand independent shop though. At first we had two machines, and we'd have to grab the right one for the car we were working. Khameleon is what we used, the "yellow" was just while it was itself, as in the process of a push-pull coolant flush it would end up picking up the color of what we were flushing out. TTP-thanks for the heads up about freezing point and straight vs pre-mix.Īntifreeze | Coolant | Khameleon | Safety-Kleen My GLA250 is a lovely little car, but it probably isn't going to make it to 15/250,000. I note in the MB 310.1 coolant specs that SSBGLA45 shared with us, change intervals for post m.y. It may be a relatively moot point, because most antifreeze these days is very long life, and you may not need to mess with it much. As TheThirdPhase recommends, using the antifreeze sold by your car maker for your car might be the smartest move. In fact it would appear that looking at anti-freeze color is not a good way to choose anti-freeze. Actually a jumble of different colors, some of which could be used together, some not at all. In the intervening years there have been pink, Japanese green, red, and gold, with various mixes of rust/corrosion inhibitors. Orange and yellow could not be used with copper/brass radiators. Somewhere in the 1990's car makers were going more to aluminum radiators, and were using organic acids as rust and corrosion inhibitors and life extenders. Although the ethylene glycol part was stable, the silicates degraded, so that radiators had to be flushed and refilled fairly often. The original US antifreeze was green and had silicate inorganic rust and corrosion inhibitors, and was for use in cars with copper/brass radiators/cooling systems. ![]()
