Was thinking, the upper driver side valve can be removed without removing the radiator. My bad (sorry long Tall Sally). The upper passenger side valve can be too but you have to disconnect the power steering [FONT=
]reservoir[/FONT]. The bottom two...maybe a midget with four hands. The problem is if one valve is problematic, all four should be checked hence the radiator removal idea I got hung up on.
Poss 1:The valve is a simple robust sleeve design and is probably just fouled with dirty oil. Someone before you may have missed an oil change too often. I think they can be cleaned (haven't done that but have looked at them) and not need to be replaced.
Poss 2: If the actuator is not getting proper signal or the actuator magnet is damaged (1/$), the scan tool will say it's the valve ($$$$^2). A dealer tech that doesn't care will send you on a expensive goose chase.
