Racing Engine Coolant Additives
Is engine coolant the same as antifreeze?
No. Though engine coolant and antifreeze serve the same purposeâ€â€to keep your engine from freezing up or overheatingâ€â€they are not the same. Antifreeze is a concentrated glycol-based solution that must be diluted with water before use. Engine coolant is a 50/50 mixture of antifreeze and distilled water so no dilution is necessary.
Can I add water to my engine coolant?
Engine coolant is already pre-diluted with water, so no addition is necessary. Though a little bit of water added to the engine coolant won’t cause damage, adding too much will reduce its effectiveness.
