Does not have an electric cooling fan do you mean hydraulic clutch fan is staying on or is making noise at this drawing air through the condenser? Has anyone checked the vacuum on the engine at idle and on snap throttle to see if it's responding correctly? Did you run a cylinder compression test yet? Did anybody check fuel pressure?
