I have a 1991 240 Volvo. While driving the engine temperture rises just below the dangerous red area, it'll then drop to normal and again after a short while rise to the red line again. I changed the thermostat but the problem continues. I thought that the radiator may not have enough anti-freeze in it to circulate properly, but because the radiator doesn't have a cap on it I can't check the level. Anyone have any ideas, clutch fan, water pump, or what?

The volvo is designed without a radiator inlet hole. The anti-freeze is fed to the radiator/engine through the over flow reservoir which has a feeding hose about 3/4 of the way up on the side of the radiator.

No radiator cap?? That is strange. I would find a RADIATOR SHOP, not auto repair< and have it looked at. I would suggest the rad. may be partially plugged.

Feel the upper hose and check for excessive pressure, you may be dealing with a headgasket issue

Put a radiator cap on it.
