I like the manual windows on the Colorado. I have never seen the point in electric windows, they cost more and there is more to go wrong. I have never had a problem with manual windows and the effort to work them is minimal.
Too many things could be the problem. First would be to of course check the filter for crud. If that's dirty, dropping the fuel tank and cleaning it out would be in order. The pump should also be replaced if the innards are rotten. ALSO, there's the distinct possibility that the carburetor needs a rebuild... The accelerator pump being bad would definitely cause the car to die if it's not operating properly. ALSO... checking the ignition timing and setting it to compensate for timing chain slack always helps. And TAKE CARE of that exhaust leak... It could potentially lead to burnt valves... And you'd be surprised at the extra power that it's robbing. But don't worry too much... That car is incredibly clean and well worth any mechanical work that it might need. The important thing is to keep it exercised after everything is tightened up!
Regarding the radio/stereo: There is a plastic frame to fit where original radio is mounted. This allows you to mount any standard aftermarket radio. There is also the possibility to mount a radio in the lower compartment (in front of the gear shifter) with a similar frame. But it's better to mount it in the upper pocket. There is also a special frame to mount several gauges (volt, oil pressure etc) in a row in the upper compartment. Ps: Many car enthusiasts here puts a Chevy small block in Volvo 240. Then you need a 1031 rear axle with a diff, a support between the front shock towers and one support going from each shock tower to the firewall to handle the torque. /A Swedish Volvo guy.
I just remove and kit the carbs If engine junk I remove carbs and dump fuel out and into zip lock bags with information on engine size 😊 Very few people will have the electric start fixed but they sale good if they do 😊
Check the ac fuse as well before getting any freon for recharging. Also like a few others have said, the thermostat housing looks possibly wet near the base if the neck. Could be a hairline crack or could be nothing. On the fullsize. For the Colorado, make sure to get a new valve cover gasket before pulling the cover off to check the timing chain slack. Also fuse check that one too for ac issues before going deeper for compressor replacements or recharging. Either way, good snags.
i would have the cylinder deactivation tuned out of that silverado if you keep it. those trucks are notorious for having valvetrain issues around that mileage with AFM/DFM activated
