850 dash lights 850

my 95 850 is having dash light issues. the first light to come on was the coolant light about two months ago... and recently followed by the check engine light. i read some previous threads on brickboard about the coolant light coming on due to a faulty/dirty sensor in the reservoir, but that doesn't seem to be my problem. i just took my brick to a shop here in fairfax. they hooked it up to the volvo computer and ran a diagnostic which came up negative. no problems, no errors in the sensors. they also pressure tested the coolant system without a problem. they reset the check engine light, which seemed to be a fluke, but the coolant light will not go away. anyone else having/had this issue? what can i do?

on a positive note, the shop that did the diagnostics was Chantilly Motors. so far i have had pretty good luck with them. and even with the tests they ran, they didn't charge me for having no fault found.

    "I read some previous threads onbrickboard about the coolant light coming on due to a faulty/dirty sensor in the reservoir, but that doesn't seem to be my problem."

    How do you know that it is not your problem.

    From the way you wrote your post it sounds like you suspected that the sensor might be the problem, but you took it to the dealer, who ran some diagnostics, which came up clean, so you've decided the sensor is good.

    If this was your thinking, it is wrong.

    Just because the diagnostics came up clean does not mean that the sensor is good.

    Have someone test the sensor itself.

      i took it to a volvo specialist, not the dealer. dealers are bandits.

      i suggested several times that the sensor itself may be faulty, but the tech insisted that the diagnostic would have found the sensor failure. it is possible that he was too lazy to delve further into the problem, but judging by the number of volvos in his lot (at any given time), i would think he knows what he's doing.

      thanks for the opinion, though.
