    coolent question

    my radiator and cooling system are currently at shops getting serviced after rust was found. i suspect they will just use a generic brand of coolent to refll it.
    so my question was how bad is this/ is there a different between generic and subaru brand coolent?
    and if so how difficult is it to change?
    thanks

    The motor is aluminum. The Subaru coolant is formulated for this. The question is whether the generic will not only be formulated for Al but also not clash with the Subaru coolant in your car already and result in a precipitate. This is possible but as more and more motors are Al it is not as likely as it may have been in the past. Just tell them to use Subaru coolant. Changing is not difficult.

    As SD stated, make sure it's formulated for use with aluminum engines.

    If they're doing a complete flush, I see no problems with using a different brand of coolant, so long as you don't go mixing things. When you start mixing different makes of coolant, you run into problems.
