    Do you know, by any chance, how well this cooling system has been maintained over its lifetime? IOW, is the condition of this valve a result of only one or two coolant changes in the car's lifetime? It would be sort of interesting to see what the valve looks like from a car that's had new blue stuff every two years.

    I do not mean complete disassembling, just clean that part. See first pic and this one

    Gee, they're kludged but it looks like they'd still work.... (perhaps NOT)

    How much the PO sucked u can tell from the cooling system, always.

    Trouble with most is by the time they are this 'kludged-up' the shaft seals are gone and the solenoids have filled with coolant- over the space of a few years causing a terminal 'oxidisation+kludge' problem fixable only by replacing the solenoid (or more often the valve itself).

    My valve body refused to divide very well (it is very easy to have it come off crookedly and thus break the shafts on the little valves) though I think mine broke in use as I noticed the broken bits before I it blew apart. See my previous posts on them for pics.

    ps. If anyone has an old valve, PM me, I need one of those two little valves from inside to make mine work!

    What's the usual life span on those ? I have no record of mine being replaced by the PO (that I can recall anyhow).
