I bought a 1992 Volvo 740 Wagon today with the SOHC non turbo 2.3l engine. It appears to be unmolested and has a little over 181k miles on it and working AC. There are a couple of things it is doing and I would love some insight.
1.) Vibration: It vibrates like crazy and it seems to be drivetrain vibration. It kinda fluctuates with RPMs and what gear it is in. It's kinda loud driving too. Never owned a Volvo before so i do not know how they drive. Good thing for you guys.
2.) Loud Valves: Yeah, they are a little loud and I'm wondering if adjustment is a solution. I have a Chilton's manual in the mail from half.com already for specs.
3.) AC Cuts Out: Going up inclines (not steep either) the HVAC fan blowers slows down to almost nothing and then blows better again at the top of the hill. Now I have heard of AC compressors shutting off under heavier loads but never the HVAC fan. Any idea what this is.
I bought all new fluids (engine oil, trans, rear diff) as well as filters (air, oil, trans) and plan on adding a bottle of Lucas trans fix and a can of SeaFoam to the crankcase when I do the oil change. What else should I do?
If anyone has any insight to this car or can share a link that lists a ton of information about it I would be very grateful.
