They said in case of an emergency I could add upto 100 ml of mineral water to top up the coolant. The folks at the Triumph dealership specifically asked me not use any other coolant. So coming back to Triumph and its proprietary HD4X Hybrid OAT, the name tell me that it’s a Hybrid coolant that’s specially designed for Triumph engines and the cooling systems they use. So that’s why it’s important to use the right coolant to cool your engine otherwise you run the risk of slowly eroding parts of your engine and its cooling system. Inorganic salts protect parts of the coolant systems belonging to older engines, whereas organic acids are good at protecting more fancy metals like aluminium and magnesium which are use in modern engines and cooling systems. Hybrid coolants use both thereby enjoying the best of both worlds.Īnd now for the all important piece of information. Traditional coolants use inorganic salts as corrosion inhibitors whereas OAT coolants use organic acids. There are three types of coolants: traditional, OAT (Organic Acid Technology) and Hybrid. The third property is achieved by adding chemicals called corrosion inhibitors which is where things get interesting. Glycols are liquids that exhibit the first two properties and are used as coolants. Liquid cooled engines have a coolant flowing through them whose job is to transfer heat from the engine to the environment.Ĭoolants need to have three basic properties:Ģ) Should not boil and vaporise at operating conditionsģ) Should not corrode parts of the cooling system (engine block, radiator, etc.) Another third is ejected out of the engine through the hot exhaust gases and the remaining third gets absorbed by the engine making it hot, thereby creating the need to cool it down. Turns out only a third of the heat generated by the explosion of fuel in an internal combustion gets used to turn the crank shaft of the engine. However I ended up doing some research on the topic which has prompted me to write this. Since the closest one is in a different state, I figured I could buy a coolant with the same specification. Triumph HD4X is a HOAT coolant, and specifically a Si-Oat coolant.I was looking to buy a can of engine coolant to store in the luggage of my Triumph Tiger 800 XRx in case of emergency and ended up learning that Triumph uses a proprietary coolant called “HD4X Hybrid OAT” which is available at Triumph dealerships only. I just ordered some of the new stuff (D2053 - #T4007771) so I can sleep at night. He didn't know the details of the change but believed that Triumph discovered issues with the old formula. I just spoke at length w/my favorite dealer (Motopia in Albuquerque) and they now stock the new coolant formula and no longer use the old stuff (HD4X). The important thing I got from all of this is that you DO NOT want a silicate-free coolant like others are recommending. I called Triumph and asked what the difference was and he referred me to their technical information site which costs $9/month. ![]() This article references the HD4X product but now Triumph's changed the recommendation to the D2053.
