My service station did a partial AC charge because it was blowing hot air, 4 days later I noticed a pool of coolant on the driveway and the AC is blowing warm air again.


Clearly you have a leak inspect your ac compressor and hoses if you cant find it i suggest use die and trace to leak as you know ac system need to be seal 100 percent in order the function i asume you have lose nuts or crack on your hoses its easy fix.

Air conditioning clog kia soul


Ac hoses do not clog as they are full of refrigerant gas that is filtered by the receiver drier.. So if you mean the drain hose at the bottom of the ac chamber in the car then remove the hose and blow it out. remove all the gunk from inside the ac chamber and check that the fins of the evaporator are not full of gunk as well. If they are get a house hold ac fin cleaner and clean the evaporator out.

03 buick century, ac control knob blows out on all vents regardless where I position it. David


This usually is related to the vacuum reservior tank/cannister or the hose leading to that chamber. Any other vacuum hose leak could cause a similar problem depending upon it's location.

The hose leading to the cannister is usually just a thin single hose/tube leading to the cannister. The system allows vacuum to build up in the vehicle and maintains vacuum on the A/C system under heavy acceleration where a loss of vacuum would cause the A/C to change operation (switching from defrost to other venting and vice-versa) due to the loss.

You could have a cracked vacuum hose, or a cracked cannister.

You can use regular carburetor cleaner in a spray can with a nozzle, and carefully spray the vacuum lines on your vehicle when idling, and should notice a change in RPMs if you spray near a leak. Only spray a small amount at a time and let the engine compartment air out between spraying/testing since this is a flammable product.

This should lead you to identify any leaks.

Good luck!

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

99 cavalier A/c doesnt work. Tried recharging still doesnt work. took to a mechanic he said maybe a small leak in the a/c hose but shouldnt be a problem... well it is a problem its hot as **** and i have...


check for a leak by installing a ac charge refrigerant with leak detector dye, it is harmless and made for this exact purpose to take all the guess work out, any mechanic that told you a small leak in your AC is okay is an Idiot BOZO, an AC system has to be 100% sealed fro many reasons excluding the har to the atmosphere from the chemical refrigerant. Moisture is an AC systems worst enemy so no leaks can exist, again install leak detector and find and repair leak... be done...please rate my help, thanks...

Oil Leak


The oil leak at bottom of radiator could be oil cooler and/or supply hose. Try check closely for wettest area .
The other leak could be thermostat cover, it only uses a sealing ring and is prone to leaking after time.
