1. Coolant: Coolant, also known as antifreeze, is a colored liquid used in internal combustion engines to regulate engine temperature. It is typically a mixture of water and ethylene glycol or propylene glycol, with added corrosion inhibitors and dyes for identification purposes. If the coolant is low or has leaked, it can cause the engine to overheat or freeze. Pink coolant is often used to distinguish it from other types of coolants, such as green or blue coolant.
2. Transmission Fluid: Some automatic transmission fluids are dyed pink to make them easily identifiable. If there is a leak in the transmission system, it can cause the pink fluid to leak out.
3. Power Steering Fluid: Power steering fluid is another fluid that is often dyed pink. If there is a leak in the power steering system, it can also cause pink fluid to leak out.
If you are unsure about what the pink fluid is, it is best to consult with a qualified mechanic for proper identification and repair.
