What type of power steering fluid does a 86 Volvo 240 wagon use?

Most Power Steering units use the generic power steering fluid available at most auto part stores. However, some import makes are different, sometimes using different fluid types in different years. Your best bet is to check the manual for the correct type. Volvo 240 manual specifies the following: Power steering fluid Capacity: 0.8 US qts = 0.75 liters.

Fluid type: ATF

Replace: no fluid change required.

The dipstick is attached to the cap. Fluid level should be between MIN and MAX marks. Add fluid when the level is at the ADD mark. The ATF in question is Dexron/Mercon, also used in the 240's automatic transmission. You may find it in different types, like II or III. The later type supersedes and replaces the older type. If you have to add fluid more often than once every couple of months, look for leaks. Hoses would be the first place to check, followed by pump and rack.
