Warning: Do not open the expansion tank cap when the engine is hot.
1. Check the coolant level. The level should be between the MAX (HOT) mark and the MIN (COLD) mark on the side of the expansion tank. If the level is below the MIN mark, proceed as follows.
2. Place a thick cloth on the expansion tank cap and slowly turn it counterclockwise. Release the pressure in the system, then turn the cap further and remove it.
3. Bring the fluid level up to the MAX mark by adding a mixture of antifreeze of the correct type and concentration (see illustration). In extreme cases, water can be used. Do not add cold water to an overheated engine.
4. Install the expansion tank cap. If frequent refilling is required, check the system for leaks.
