From the "high horsepower in a small package" super pee-wee racing machines to the big bore four-stroke machines famous for churning out massive heat, Engine Ice proved to be the coolant of choice of top racers everywhere. All the ingredients of X1 are generally recognized as safe (GRAS) by the US FDA so there is no need to worry about the safety of the product in your home.

To drain it, I just use the fast and easy method of removing the lower radiator hose, but there is a very detailed post and pictures on here somewhere by Dave C on the correct way to do it. With the new liquid surface tension optimizer added to the formula, P1000 Pastel Coolant Series has minimized the risk of airlock and made filling up your system easy! DEX-COOL antifreeze uses two inhibitors: sebacate and 2-EHA (2-ethylhexanoic acid), the latter which works well with the hard water found in the US, but is a plasticizer which can cause gaskets to leak. So if it (in theory) helps keep isolated areas of my engine head cooler and it doesn't hinder but can help. Also unless I’m seriously mistaken “Engine Ice” is designed to help keep engine temps down/stable while racing and does Not have antifreeze characteristics.

While it's true, you won't lose coolant; your engine components will get to temperatures that they are not designed for and could ultimately lead to engine failure. Straight water actually cools better than any coolant mix, but it will boil at around 230-240 under a pressure cap. If you live in an area that encounters freezing temperatures, you could be aware of pipes splitting inside your home.Rapid Cool Blue Antifreeze contains corrosion inhibitors suitable for aluminium engines and is suitable for use in petrol and diesel engines.

In a service department scenario, the recommended action is to flush and change simultaneously with an oil change.As for the original question, if you are just slightly low, and need to top off, you should be able just to use distilled water if it isn't enough to change the mix ratio much. Viscosity affects the fluidity of coolant, lower viscosity indicates less resistance therefore better flow of coolant. Before adding coolant your cooling system must be clean and have no chemicals of any kind left in the coolant loop. In the case of a head gasket, it doesn't have to overheat to expel coolant, as it pumps the cooling system full of over the limit pressure. Thanks to the TT exclusive formula, the old days of repeatedly unplugging the system or waiting for 12 to 24 hours for the air to clear out after filling the loop is behind us.

The rear cyl will drain as is and the front, hell, not enough to bother with removing the screw unless you are switching antifreeze brands and want the last tea spoon out of the system. Reinstall drain plug to proper torque specifications and pour ready to use Engine Ice to top of radiator. No problem tooth, though as others have pointed out, I misspoke, going by color alone isn't a good idea, especially across manufacturers. I would've expected at least 5 minutes from a cold start (unless cold start means sitting in the sun in 110F weather or something like that, but still wouldn't expect 30s). If you fill it to the top, just warming up to 255 will force some coolant out due to expansion, but the coolant level should settle out right about where the cold coolant is just at the tops of the radiator core tubes.

Since the technician is already disassembling the machine for an oil change, there is not much additional time associated with the coolant change and flush.
