So I need some ideas as to what problem I'm having. This doesn't have to do with my mustang, it has to do with my volvo but I figured the cooling system is basically the same from car to car. I have replaced the waterpump and thermostat on my 86 volvo 740. There does not appear to be any leaks. The return hose from the thermostat housing gets warm/hot and the waterpump hose gets warm. The system also appears to be getting pressurized. The heater blows cold and the car slowly creeps up in temperature until I wont let it get any hotter and kill the car. What issue could I be having? Should I check the thermostat? The radiator doesn't look original and it looks fairly new. Could it need a system flush? Any ideas as to what it could be would be appreciated.

As an aside I removed the cracked fan shroud until I have time to get another one. Do those things make that big of a difference as far as drawing air into the radiator?
