What is what car fluid is red?

One common red car fluid is automatic transmission fluid (ATF). ATF is a specialized fluid used in automatic transmissions to lubricate moving parts, prevent overheating, and ensure smooth shifting. It is typically red or reddish in color to help differentiate it from other automotive fluids.

ATF can also be used in some power steering systems, depending on the manufacturer's specifications. It is important to regularly check the level and condition of ATF in your vehicle to ensure smooth operation and prevent damage to the transmission. If the ATF appears to be a dark, burnt, or discolored red, it may indicate a problem with the transmission and should be checked by a professional mechanic.

Other red car fluids may include power steering fluid, hydraulic brake fluid, or coolant. It is important to consult your vehicle's owner's manual to identify the type of red fluid in your car and follow the recommended maintenance schedule for checking and replacing it.
