2008 Impreza 4EAT 2.5i Differential Fluid Capacities?

LethalMonk6 · 05-16-2013, 07:03 PM

I'm having trouble finding how much differential fluid I need for the front and rear differential on my 2008 Impreza OBS, with 4EAT.

I've bought 2 quarts of 75w90, will this be enough for both?

The rear takes .8 and the front takes 1.2-1.4. It may be hard to get it into the rear. What I did was get a hand pump that fit the bottle and pumped away. PITA but it worked for me. If you spill some 2 quarts may be running close. You can choose to have an extra just in case. After you do the rear throw the rest of that bottle and a whole new one in the front diff. Then check the level. You should do your trans fluid too if you haven't already. Just replace as much as you took out. I did my coolant at the same time as well as pcv valve, brake flush
