If you have high head pressure, first check you condenser fan relay switch & fuse, located between the fender well & fuse link box drivers side. If your fan is not running, you will develop high head pressure. Second, you may have a stopped up expansion valve. If you do not have the equipment to do so, you need to take it to a repair shop & if they do replace it, make sure the blow out your condenser & evaporator coil while the system is down.

Kia picanto drive time ac good cooling traffic stop time not cooling


check that the fan for the condenser is working
with the vehicle moving the air flow will keep the compressor pressure down but when stationary and no air flow the gas pressure will go too high and the high pressure switch will stop the compressor
have it inspected by an accredited ac specialist shop

On my 2006 ac works good when engine is cool, in stop & go traffic it blows hot air & head pressure gets high in ac, car temp is ok what's wrong


How do you know head pressure is high? Do you have an auxiliary electric cooling fan that is not coming on in this situation? It should be in front of the AC condensing coil. There may be a switch tied to the system that is bad. This switch is sometimes activated by the pressure in the high-pressure line to the condenser coil. If there is not enough freon (134a) the pressure will not be high enough to activate the cooling fan switch. I recently added one can to my system and it made the fan run whereas it did not before adding the freon.

Why does my montero cooing system makes gurgling noise


In many cases of gurgling cooling system, you have a possible head gasket problem starting and the combustion from the engine is pressurizing the cooling system. Check your cooling system thoroughly for evidence of a possible blown head gasket.
Are you loosing cooling system water?
Is your radiator overflow tank being pressurized excessively by the engine. Headgasket problems can sometimes put some much pressure in that overflow tank that it begins to bulge outward.
Check the oil and look for any white/greyish milk shake consistency fluid on the oil fill cap or on the radiator cap. Keep a close eye on your oil and water levels if your gurgling sound continues. This is not normal and again, usually is a sign that there is a possible leak between the headgasket and a water jacket on the head.
Did you overheat the vehicle anytime soon? This will many times breech a head gasket between water jackets and begin spraying water in small amounts right into the engine cylinders, while it pressurizes the cooling system and makes gurgling noises.

A local garage mechanic says the clutch has stopped working on ac that is why it blows hot air instead of cool says it will cost $900. to fix cause I have to buy the whole ac unit does this sound correct?...


have you tried charging the ac system? most ac compressors have a pressure switch that will not allow the relay to engage the clutch if the coolant pressure is low. $15 can of r134a and maybe a $20 Haynes manual is well worth the price difference, eh?

My 2004 Montero Sport a/c problem


If the fan doesnt run with the A/C on then something's wrong.
Fan will run intermittently but not necessarily permanently with the air conditioner compressor running.

Have it troubleshooted by a mechanic.
