My '84 SD only warms up to 60 deg C after an 8 mile drive. To save money, I'm tempted to attempt to change the thermostat myself. I'm not sure where the thermostat goes, but I would expect to have to drain the coolant from the radiator.

How much coolant do I need to / should I expect to catch to get below the level of the thermostat? Is there anything else I'd need to buy, such as a gasket, etc.? Thanks in advance.
