Hi,
Just got it a week ago and I have done some work on it such as a new front link bar and Track rod end.
The usual issues I can sort out such as the Belt tensioner and such but never got an owners manual with it and I have two dash warning lights which I have no idea about.

Light one is the coolant light which remains on even though the car is loosing no water and I never had to top it up or anyhting, no over heating to indicate a Head gasket. Can someone tell me were I can locate the sensor for this 1993 model?

Light two is orange with a green almost distorted triangle in the middle and this really throws me. Any Ideas?

Thanks for the help folks.

The first light for the coolant comes from a sensor in the expansion tank itself. See if one of the sensors has become dislodged and it floating up or is disconnected under that tank. You can buy a new tank and/or sensors from www.fcpgroton.com for a fairly cheap price. Second sensor sounds like a the sensor you often see when an 02 sensor goes bad. Have the codes read or read them yourself. This will tell you how to read the code: http://www.volvospeed.com/CheckEngine.php You want to find out what the DTC (diagnostic trouble code) is. Also, read up on all of your maintenance for this vehicle here: http://www.volvospeed.com/maintence.htm#Misc
Furthermore, here's your owner's manual: http://apps.volvocars.us/ownersdocs/199 ... 850_1.html
Hope this helps.
