How to Add Engine Coolant in a 1994 Buick

Maintaining proper radiator coolant levels in your 1994 Buick prevents engine overheating. All General Motors vehicles use a specific brand of antifreeze called Dex-Cool. According to General Motors, the use of any other fluid could cause catastrophic radiator and coolant system failure. Dex-Cool is required because its chemical makeup does not damage the metals in the 1994 Buick radiator.

Things You'll Need:

• Distilled water
• Dex-Cool antifreeze

1. Open the engine hood by pulling the hood release tab

Open the engine hood by pulling the hood release tab located under the dashboard on the driver’s side of the vehicle. Secure the hood in the open position with the hood prop.

2. Remove the radiator cap from the filler spout

Remove the radiator cap from the filler spout on top of the radiator by turning the cap counterclockwise. Never remove the radiator cap when your Buick is hot, because the coolant system is pressurized.

3. Pour a mixture that is half distilled water and half Dex-Cool antifreeze

Pour a mixture that is half distilled water and half Dex-Cool antifreeze into the filler spout of the radiator until the fluid level is within one inch of the top of the filler spout.

4. Start the Buick engine

Start the Buick engine. Turn the heater on to its highest level. Let the vehicle idle for about five minutes to purge the radiator of any air in the system. Turn off the Buick engine. Add fluid until the fluid level is within one inch of the top of the filler spout.

5. Put the radiator cap back on the radiator

Put the radiator cap back on the radiator filler spout by turning the cap clockwise.

• This was really helpful my car has the 2nd type you showed in the video and anywhere I would take my car to ask about how to fill it while showing a picture of the inside of my hood 90% of the people I asked had no clue what to even tell me so thank you for this it really helped
• One thing this didn't show is putting your heater on full blast too.. that way the coolant gets circulated through the heater core and helps to get air out of the lines.
