I'm having trouble with the coolant. There's no leaking on the floor, but the coolant fluid isn't lasting more than around 5 days. The heating doesn't work – only cold air blows out. Even though it's summer now, I want to get this fixed now and not wait until next winter. What do I do to solve these problems?

Antifreeze leaks can be caused by a variety of things but the two most common factors are age and dirty coolant. Dirt or oil in your coolant can accelerate wear in your system, leading to leaks in your water pumps, at gaskets, or at o-rings. Flushing your cooling system is the best way to stop this type of leak.
Leaks in The Coolant System
Any signs of leakage in the coolant system can cause the coolant level to drop and make the reservoir empty which may translate to various engine problems. So, make sure that you look for any signs of leakage in the coolant system.
While Mini Coopers are known to be high-quality vehicles, they have been known to experience coolant leaks. Some of the older models of MINIs are known to experience radiator and thermostat housing leaks, but the most common problem with a coolant leak in a Mini Cooper is a faulty water pump.
Other Reasons Coolant Is Disappearing
Another reason the coolant in your car may be disappearing without any visible trace is because the leaking coolant is coming in contact with the engine block and burning up. This scenario may be a small problem like a crack in a hose or a big problem—more on that in a bit.
It may be a broken hose and/or a hole in the radiator. Solution: Check your hoses to see if any coolant is coming out. Replace the hose(s) if you notice coolant coming out of them. If you notice coolant leaking out of your thermostat that can be an easy fix.
Some of the most common issues that cause engine overheating, particularly in MINIs or BMWs are: low coolant levels (possibly due to engine leaks), radiator malfunction or failure, or water pump failure.
Generally speaking, the operation of the AC system should not create a coolant leak to occur, as coolant does not flow through the AC unit in any capacity. However, an engine will “work harder” when the AC is on, so smaller leaks may increase in volume when this occurs.
How much coolant loss is normal? Providing that the engine is running well, with no leakages or damage, you can expect a coolant loss of 0.25% every four to six months. This means a loss of two to three ounces a year is completely normal.
A faulty radiator cap can result in engine overheating, loss of coolant or major engine damage. So, Pressurized cooling systems help prevent overheating and coolant loss.
There is an easy way to find out if your engine`s head gasket has blown. Simply check under the oil filler cap. If the gasket is not damaged, the inside of the oil cap will be mostly dry. If you discover a milky brownish-yellow substance that is similar to the thickness of a milkshake, you probably have a gasket leak.
The normal engine operating temperature for a Mini Cooper can range between 195°F (90°C) and 220°F (105°C), depending on factors such as driving conditions and engine modifications.
The MINI Cooper S holds 6 liters or roughly 1.5 gallons of coolant so make sure that whatever container you use is capable of holding all of that coolant.

If there is a leak found in the refrigerant lines themselves, it`s possible to replace them but the refrigerant will need to be recovered and then replaced as well. The copper lines should be purged with nitrogen as well to clean them of any debris that can damage the compressor.
A leak in your refrigerant means that your sealed system is no longer sealed. This creates a few problems: Most obviously, a freon leak will prevent your vehicle from retaining the refrigerant. To keep your AC system working, you need to find and repair leaks at the source.
Most of the time, excess coolant is expelled from an overflow hose. You`ll likely see a puddle of coolant beneath your car if this has happened. In worst case scenarios, overfilling your antifreeze tank can lead to electrical damage if overflow comes into contact with engine wiring.
The average cost for a Mini Cooper Water Pump Replacement is between $848 and $991. Labor costs are estimated between $447 and $564 while parts are priced between $401 and $427.
With the engine off, open your hood and locate the water pump pulley. With gloves on, grab it and wiggle it back and forth. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem.
Overheating. A dead or dying water pump cannot circulate coolant through your vehicle`s engine and, as such, the engine will overheat. The hotter the engine gets the greater the chance of serious damage, including a cracked engine block and damage to the cylinders, pistons, and head gasket.
Refilling your coolant is a normal part of car maintenance. But if you find you have to top off your coolant frequently, this could indicate your car is leaking coolant. If this is the case, you need have a specialist at Natrad inspect your cooling system.
Start your car`s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
Corrosion within the radiator is one of the leading reasons that coolant leaks. As the tubes get older and weaker, you may get sediment or debris inside that causes a leak. The sealing gasket between the tank and the radiator can also wear out, and that could lead to a leak.
This deteriorated liquid can trigger severe harm to your engine by failing to control the temperature. Therefore, manufacturers suggest replacing the coolant periodically. It is recommended you change coolant after the first 210,000 km (140,000 miles) or 120 months, then every 30,000 km (20,000 miles) or 24 months.
