You dont add coolant to centrl air systems. They have to be charged with the appropriate refrigerant by an EPA certified technician. If the unit seems to not be cooling sufficiently that would be your sign to call someone. this is generally an item checked on an annually cooling heating inspection and tune up. Unless the unit is very old or leaking refrigerant somewhere there really shouldn't be an issue since it is a closed system. Be sure you need a recharge before asking for one, it is not cheap by any means, depending on the type of refrigerant it can run you anywhere from 25-55 dollars per pound and the typical system takes 6-10 pounds to charge fully.

Cannot locate cold fill line on impala 2008 coolant overflow tank


Just fill it up 1/4 full with coolent. Coolent expands when hot, which will fill the tank up more, so don't over fill too much. If you think your low on coolent, let the engine cool down, and open the radiator cap and fill it full from there. Filling the tank, will not add ANY coolent to the radiator untill it warms up (expands) and cools down (contracts pulling in coolent from the tank only at this moment.)

Found oil in my coolent expansion tank


Generally speaking, if you have engine oil in the cooling system, you have a leak somewhere in the engine, which could be a head gasket.
Is there any sign of coolant in the engine oil ?

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

2001 xtera loosing coolent but don't know where from


These engines had some issues with headgaskets leaking coolant externally. It is a small leak and usually only when hot, so there is no puddle because the coolant evaporates before it gets off of the block.

Get under the vehicle and, using a light, look at the rear face of both cylinder heads. If you see a greenish-white stain, that's the issue. This is a very labor-intensive job and should only be attempted by a qualified technician. I don't know your experience level, so I can't say whether you should try this yourself or not.

If you don't see any staining, a cooling system pressure test would be in order.

If you're located somewhere in central Pennsylvania, I could probably help you out.

Hope this is helpful!

Fridge not cooling


If you look in the outside compartment do you see a yellowish powder? If you do, or if you smell amonia probably the cooling unit has leaked the coolant. It does not help to add coolant, it will just leak out again quickly. You will need a new fridge or to have the cooling unit replaced. If that is the problem, Dometic has a recall on some models for leaks and will pay for a new cooling unit.
