The answer in most cases is YES. The reason that the air is coming out of the condensate overflow (drain) tubes is because there is a positive air pressure being exerted by air handler or furnace. There are some systems where there is a negative air draw on the drain and could possibly be capped. Depending on the configuration of the unit and the location of the evaporator coil it could be a normal part of the operation of the condensate overflow to have air coming out. Depending on the way the condensate drain was designed, it may be required to be "open" in order to drain properly. Covering or capping the drain opening could cause it not drain properly or back up. There is no way to know if should be covered or not from a discussion. You would have to see the actual drain design and orientation of the equipment to decide if it should be covered. It was designed and installed that way then leave it alone. Otherwise, a professional should SEE it before making any changes.
yes
If it's part of the AC system you're just getting a little condensate from the cooling coils. Often the defroster will also cause a little condensate to build up. It has to go somewhere and many auto manufacturers have a tube or other device for allowing the condensate to leak out. Not only is it normal, it's necessary to get rid of the condensate.
Well, no. But its normal for the float in the carb to get get stuck and cause the gas to overflow through the overflow tube.
Is the temp. light coming on? Check your coolant level in the overflow reservoir If the level is to low it could cause the fan to run more than normal. I have a 2002 Sportsman 500 and my light was coming on and the fan was running more than normal. I had a pin hole leak in the tubing between the radiator and the overflow reservoir This was causing it to leak antifreeze and allowing it to suck air into the cooling system. Which was causing my fan to run and my temp light to come on.
this sounds like a bad thing to me...like the reservoir and/or the cooling system, has no antifreeze in it and heat from the engine is exiting through the cooling system. Does your temperature gauge read in the normal range? Is the car running OK? FriPilot
A gurgling sound and increased water production can indicate a clogged condensate line or drain issues in your central AC unit. This is not normal operation, even in hot temperatures. It's best to have a professional HVAC technician check and resolve the issue to prevent potential damage to the system.
Condensate dripping from your AC is normal and not considered a leak. Anything else is bad.
Normal Running temp is 200 degees.
The Normal running temp is 180 - 190
In all probability you either have a bad radiator cap or an air lock.
A lot of heat is gonna build up when there is no air going through the radiator fins. This is one way that the cars vents some of this pressure. It is possible that it had too much coolant in it and the overflow tank filled up and pushed the rest out the overfrlow tube. It is normal for coolant to go back and forth between the overflow tank and the radiator. Just keep an eye on it and if it is not over heating then I wouldn't worry about it. Good luck.
It most likely means that the unit is working as it should. Some explanation is in order... First the air conditioner in your home is designed to cool the air. When air cools, any moisture that is in the air gets squeezed out. This is called condensation. Most air conditioners have a condensate pan buildt into the unit, and a line coming out of the pan through which the condensate can and will flow under normal conditions. Most units also have a secondary drain line. if water is comming out of this line then the firs is possibly obstructed. Hope this helps Terry Good explanation but if I'm understanding the definition of overflow tube it means you have problems. In my house, one of our A/C units is in the attic and has 2 drains. It has 1)a primary that drains to the house sewer system and 2)a catch pan under the unit that drains to a pipe and empties outside under the eaves. This is the overflow. If you see water dripping from a pipe outside, it means your primary is clogged and it should be fixed SOON. If the overflow also clogs, you'll have water damage to walls, ceiling, floors etc. We live in Texas and our air conditioner will remove gallons water from the air in a normal day. Imagine if it has nowhere to go. Riley
