Mine was low when my mechanic checked it earlier this year. This is a great reminder for me to check it again and add some or get the system checked for leaks!
Hello.
I had a similar problem on my 97 that was cause by a $2 O'ring between the top filling tank and the bottom return line tank. There is 2 O'ring in this section, and the green one was crack. check for pentosin leak often. you don't want to replace the pump $$$.
