1995 Oldsmobile Cutlass Repair Question
Asked on September 18, 2012
Won't start, pressure built up in radiator.......
The car will run great for a month or two then will not start and it has built up pressure in the radiator. Let the car sit for a day or two after removing the radiator cap, yes after it has cooled off. Then the car will run great again for another month or so. What may be the cause of this?

Do you have coolant losses or overheating issues?
When pressure builds up, does the coolant level in radiator drop?
Have you checked for trouble codes?

If there was too much pressure in the radiator it would pop the cap and the reservoir would fill up. When the problem occurs, if it cranks good but won't start, have a helper crank it while you check for spark at the plugs. If spark everywhere, use a gage and check fuel pressure.
