silicone boy Posted September 20, 2002 Share Posted September 20, 2002 I've seen this topic before, about putting oil in the strut housing like the factory manual says, to act as a heat sink. The only reason I'm bringing this up again is because I'm putting my front suspension back together and it's easier to do this now than later. Is this really necessary? I have never done this for any car I have ever owned, and I'd rather not cause it's seems kind of messy (and a waste of oil to boot). How many of you people use oil and how many have not?

RB30-ZED Posted September 20, 2002 Share Posted September 20, 2002 Yes it is necessary, as ive seen insert removed that didn't have a liquid to transfer the heat and they had burnt the paint off them, which is certainly not good for the hydraulic oil. I don't use oil as it can look like a leak. Use coolant which will do a better job and will not cause corrosion. Steven Quote Link to comment Share on other sites More sharing options...
slownrusty Posted September 20, 2002 Share Posted September 20, 2002 The oil also does a few more things as well as heat transfer: 1) Helps dampen suspension vibration (which coolant cannot do) 2) Prevents corrosion to the inside of the strut casing and the strut itself. So about 30mL of oil if strongly recommended. Good luck - Yasin Quote Link to comment Share on other sites More sharing options...
Mike C Posted September 20, 2002 Share Posted September 20, 2002 Coolant does prevent corrossion, it just doesn't "stick" to the parts as well. How can oil in the tube contribute to suspension damping? The strut insert does that and is completely self contained. The insert is solidlly bolted into the housing if installed correctly it has zero movement, thus nothing to be damped. Quote Link to comment Share on other sites More sharing options...
Mike kZ Posted September 20, 2002 Share Posted September 20, 2002 I didn't add any oil, so far so good Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 20, 2002 Share Posted September 20, 2002 I would imagine on an extreme driven machine anti freeze or oil would have an advantage in cooling properties. Anti freeze sounds like a solution that would have temperture control benefits for the hard run. Quote Link to comment Share on other sites More sharing options...
