How to replace the radiator, thermostat and hose?
Once these items are removed, you can access the hose clamp holding the upper radiator hose to the thermostat housing (See Figure 14 ). At this point, if you are not replacing the thermostat, simply put the new hose on and re-assemble the front end of the car. Replacing the thermostat is a bit tricky as it is a tight fit within the engine bay.
Where is the radiator hose on a Mini Cooper?
The upper radiator hose runs from the upper port on the radiator, through a plastic connector hose with a bleeder screw to another radiator hose that runs behind the intake manifold to the front of the thermostat housing cover. This hose is also secured in place with a small plastic hook molded into the intake manifold.
How big is the cap on a HPS heater?

Can a radiator get stuck in a heater core?
The heater core looks a lot like the radiator in miniature scale. In fact, the inside of the heater core has a similar network of small gauge tubing, which works to produce hot air for the heating system. If scales or debris break away from the radiator piping, it could end up stuck in the small tubing of the heater core.
What happens when you open the radiator cap?
This will cause air pockets to get inside of the heater core, thermostat, and radiator hoses. As a result, the engine will start to overheat because it cannot sustain a temperature that is consistent. Warning: Never open the radiator while it is hot!
How to get the top radiator hose to be hot?
1 Remove the splash tray and push the coolant catch tray in. 2 Remove the thermostat cap, usually on the top hose at the engine. 3 Clean the stat seat on the engine and cap. 4 Lube the new stat seal with fresh coolant and fit it, check the orientation (Jiggle valve up). 5 Tighten down the cap bolts and torque to approx 10Nm (89in lbs).

What does the thermostat on a radiator do?
The thermostat has a special function within the circuit, it’s job is to restrict coolant flow back to the radiator when coolant temperature is below 180 deg F (83 deg C). Above this temperature a wax filled cylinder within the stat melts and expands causing the valve to open proportionally until fully open at about 199 deg F (93 deg C).
