![]() The boiling point is really raised by the radiator cap, now on the sealed reservoir which is included in the circulatory path. # Boiling point of a 50% mix is 225F or 107.2C. Colors include blue, yellow, green, red, pink, turquoise, orange and purple. We will break it down for you to better understand why this liquid comes in a multitude of colors. This can be confusing for people who don’t know what each color indicates. # Freezing point of a 50% EG mix is -34F. Coolant (Antifreeze) can be found in more than 1 color. # Flow increase is required with EG as compared to water. With a 50% mix & temp >36F the specific heat capacity is decreased by 20%, so volume of coolant has to be increased. Consequently, the blending will have 1 quart of blue, 1 quart of green, and 2 quarts of water. If your green-blue coolant amount is 2-quart, add 2-quart of water. You must also use the same quantity of water. # Water is a better conductor of heat than ethylene glycol (EG). After blending the coolants with an equal ratio, add water to them. As I used to make wine I have a pH meter too!). ![]() SG for a 50% mix 80-100C is 0.88), 3) electrical conductivity w/ a multimeter & 4) pH (U can use strips or a pH meter. # The coolant can be tested 1) visually, 2) SG w/ an antifreeze hydrometer (not the ones used for batteries, but a wine hydrometer will do. The 1.5 dci engine was designed in 2001 w/ a cast iron block & aluminium head. Now with all aluminium parts silicates are required to prevent corrosion. In the days of 'green' there was only green! That was ok for the cast iron blocks & copper or brass radiators. I noticed that Dacia is using yellow now. Use the same colour coolant that your car came with. What would James Bond do if he didn't have any Tonic, he would add more Gin. Allow the engine to run for a few minutes so that the coolant can circulate. Once you have added the coolant, replace the cap and start the engine. Dont know where it is but there must be a drain valve for a complete (engine block) drain. Be sure to use the correct type of coolant for your Honda Accord. If you can't get yellow then add blue! Any time in the future if the coolant is being replaced then go back to blue after flushing w/ distilled water. To add coolant, remove the cap from the reservoir and slowly pour in the coolant until it reaches the fill line. I have personally done a complete job in my 2006 Corolla & it was very easy. It’s just dye that gives an antifreeze color, but those dyes are added to help keep you from using the wrong antifreeze in your vehicle, Finch said. The label recommends a 50/50 mix, but your owners manual may specify a different ratio depending on the climate in your area. My intention is not to complicate matters, but just to illustrate that the colour is a coding for different formulations.ĭraining the system & a complete flush before filling the recommended coolant is not an easy option as these cars are not designed w/ drain taps in the radiator and drainage plugs in the engine block. Add distilled water to concentrated or full-strength antifreeze. I am attaching a screenshot of a table for your reference. Your original coolant seems to have been changed in between. Renault/ Nissan/ Honda/ Hyundai use BLUE. The most difficult thing will be to flush it enough to make sure the two coolants do not mix.If COLOUR doesn't matter, then SIZE doesn't matter! I remember a quote of Henry Ford: "You can have your car in any colour you want, as long as it is BLACK". ![]() That is the reason on The Speed Bump I change coolant more often. I remember all the issues with the GM Dexcool where even if the right coolant was put it caused issues that destroyed engines and associated parts. Out of curiosity I checked my recovery tank today (there was a question as to if the level was low last time it was inspected) and mine is a light green not the usual conventional neon green. Either way get it changed somewhere else ( your driveway or a shop that cares) with a coolant for Asian cars that is whatever color. The question I would ask is if they use different coolants in different vehicles or if they claim it is universal and safe for every thing. It maybe fine but there is a reason why the different vehicles specify a different coolant which is indicated by color. They may get it in bulk and they are cheap and use the same coolant in everything. Honda Antifreeze Coolant Type 2 Recommended coolant for most Honda and Acura vehicles. The Acura coolant color is typically blue, not green. As for the abrasive quality of the silicates I think it is pick your poison. You need to know what formulation its and if anyone put the wrong color in mine that would be 2 trips in one ( first and Last). The coolant generally used in Acura vehicles is, in most cases, a Honda Type 2 engine coolant. (50/50 mix) Change it at regular intervals at or before the recommended time and mileage. Brand does not matter every brand makes multiple formulations.
