Question about 2007 Mini Cooper S Convertible

Open Question

2006 Mini S blows a short blast of hot air through the A/C.

At what sure seem s like just the time the coolant thermostat opens after the engine reaches the correct operating temperature, the cold air from the automatic A/C blows hot for maybe 5 seconds, then returns to ''normal'' operation.

Dealer says they can find nothing but recharged the A/C system. That did not help. Still have the problem.

Engine overheats and heater blowing cold air


You have air trapped in system , change thermostat , bleed air from system , let it run hot while adding coolant with blower full blast on all front and rear heaters .

yes a bad water pump will cause it not to circulate the coolant through the heater core,find your coolant leak 1st is it leaking into the cab on the passenger side of your truck? thats another sign of a bad heater core also.make sure that you don't have an air pocket in your cooling system.it has to be full for the heat to work properly.thank you for choosing fixya.com

REPLACE THERMOSTAT.MAKE SURE COOLANT SUPPLY PIPE OR COOLANT RETURN PIPE NOT STOPPED UP AND YOU HAVE ENOUGH COOLANT IN THE SYSTEM.REPLACE THERMOSTAT.CRANK ENGINE UP AND LET IDLE UNTIL WARM UP KEEP EYES ON TEMPERATURE GAUGE. WHEN ENGINE THERMOSTAT OPEN COOLANT HOSE SHOULD BE HOT.IF NOT TURN OFF ENGINE.USE LARGE RAG WAIT A WHILE BEFORE REMOVING RADIATOR CAP CHECK TO SEE IF COOLANT LEVEL DROPPING IF SO ADD MORE COOLANT.CRANK ENGINE UP UNTIL THERMOSTAT OPENS UP.HOSE WILL GET HOT.IF STILL COLD CHECK COOLANT LEVEL.ONCE YOU AIR OUT COOLANT SYSTEM RADIATOR HOSES WILL GET HOT SO YOU WILL GET HEAT.IF COOLANT LOW YOU WONT GET NO HEAT.

My heater does not blow hot air. 1 thermstat has been replaced 2 could water pump be bad 3 water does not seem to be circulating through the hoses. 4 the air mixer under the dash seems to be workig.


If the thermostat was recently replaced, it could be trapped air in the cooling system. First, you need to establish that the thermostat is working. Remove the radiator cap and start the engine. Let it warm up to normal operating temperature on the temp guage. Make sure the heater is set to the hottest setting. Observe the coolant in the radiator. If the coolant is flowing when the engine is cold, then the thermostat is stuck open and the heater won't get warm. If the coolant is not flowing, continue to watch the coolant. When the thermostat opens, the coolant level will drop in the radiator tank, add antifreeze to bring it back to full. Each time the coolant level drops, add more antifreeze. should the thermostat close while doing this, antifreeze may spill over from the radiator tank. No to worry. As son as the thermostat opens up again, add antifreeze to fill the tank. Continue to do this until the coolant level no longer drops. Sometimes it is necessary to raise the front of the vehicle so the radiator is high than the engine in order for the air to escape. Put the radiator cap back on. If the problem was air in the system, then the heater should be warm now. In the old days we would just drill two 1/8 inch holes in the new thermostat before installing it. That allowed the trapped air to escape slowly. Might still be an option.Let me know if this helps.

My mini cooper is blowing cold air inside when the car is hot and it start overheating


Clarence,
your mini-cooper may just need a new thermostat. if the thermostat in your car is the original, then 4 years is a goodly amount of time for any thermostat to last. Thermostats fail in 2 ways: (A) stuck open, which causes engine to warm really slowly, and (b) stuck closed, causing overheating and
causing the heater to blow cold air - since the heated coolant can't get past the closed thermostat to
circulate through the heater core (a small radiator-like device used to heat the interior of your car).
Your car's thermostat has failed in mode (B).
Your cost: $5-$15 at any auto parts store.
Project complexity: any handy person could teach themselves to replace a thermostat.

When the car is idling, the heater blows out cool air but when the car is moving, the heater works fine


When the coolant in the heater core is hot from the engine and your fan is on hot air will blow through the hot fan coil, i figured it out, when i stepped on the gas i could here the coolant squeezing by the control or limiter valve, because the higher rpms make the belt spin faster which makes the water pump pump harder causing more pressure, so when u idle that hot coolant will cool down from the fan blowing on it, u need to find the control valve and open it up to full blast, then hot coolant will always be flowing through your heater coil. ;)

Engine Coolant Hot Message Noticed AC was blowing hot and looked at instrument panel and saw message above. Drove short ways and an individual tried to loosen cap, of course hot coolant went everywhere....


I wouldn't think it would be the water pump mostly because they will either start to get noisy, pour coolant out of the seep hole or completely seize all of which you would probably notice. My guess would be that you have air in the system that may be causing the thermostat to remain closed or possibly a bad radiator cap and/or faulty fan clutch (usually when they "fail" they stay engaged all the time but it is worth inspecting. I was taught to ALWAYS drill a small bypass hole in the rim of ANY thermostat I replace. It helps to gradually open the thermostat during warm up and if the thermostat fails to open, there is still a passage for coolant to flow. This is a must for any GM vehicle.

Heater/defrost doesnt blow hot heater hoses one


The heater core is probably clogged. The best method i have found is to remove the heater hoses, and blast compressed air into one side or the other in short bursts. This will tend to launch a clump of sludge out of the other side, and is very messy. Once the heater core is unclogged and reconnected, it is a good idea to chemically flush the entire cooling system, then flush with clean water and refill with universal coolant.

Heater temperature does not stay hot


1st thing to check is the coolant level. I've seen cars w/ no heat, or very little quite a few times caused by low level in cooling system--not low enough to overheat the engine, but enough that circulation of coolant to heater core is affected (no or little hot coolant circulation to heater core=no or little heat),
Is the engine temp gauge in the normal range? If it's in the low range, engine not reaching operating temp. it could be caused by a thermostat stuck in the open position (or no thermostat, sometimes people remove them when their car overheats, and this should not be done).
Here's how the system works: the heater 'box' contains a heater core (a mini radiator) w/ a fan and hoses connecting the heater core to the engine cooling system. Hot engine coolant is circulated thru the heater core. When u activate the heat switch on the dash, a flap door opens to expose the heater box to the passenger compartment. The fan switch on the dash activates the fan, which blows air thru the core, which heats the air.
So, if it's not the coolant level at the radiator, the fan is obviously working, the engine is reaching operating temperature, I would say it must be the flap door that opens, isn't opening fully, or isn't staying open. It could be the dash switch is defective (not supplying current to open flap door) or less likely the flap door is binding somehow. Hope it's as simple as correcting coolant level, if not, the dash switch control should be checked
