i have a 1999 subaru legacy. i know my car is overheating but im not sure why. the cooling fans work fine and there is antifreeze in the reservoir and radiator. It was slowly rising towards the H until it went beyond it. I check under the hood and i saw that in the radiator cap, the liquid was falling through the sides. i think the antifreeze is not going through or something. what could be wrong. could it be the radiator?

try replacing the radiator cap on it first,sometimes that will cause one to run hot,,that's not a real old car ,but you may also want to change the thermostat in it,their supposed to be changed every year,but not many people do this,i use mine till it goes bad,then change it,which isn't good,but try that ,usually when you get a condition like yours is doing its the thermostat that causes it to happen,it can also be the bottom of the radiator getting stopped up on it,that too will cause it to run hot,good luck with it.

STOP all work. NEVER replace any part till you know the problem. Water pumps, thermostats, radiator caps NO NO NO. Take your car to a RADIATOR SHOP, not an auto repair shop, and let them check your radiator. I will bet it is plugged and needs cleaned. NEVER flush a radiator. It will stir up all the sediment in the system and plug the coolant passages in your radiator. Don't waste your effort on the other ideas listed here. A mekanik with 37 yeears experience should know that a radiator cap doesn't cause overheating. It may cause loss of coolant but that is not a primary cause.

either your water pump is bad or your thermostat is sticking. Oh, and btw, overheating your car will easily ruin your engine by warping the heads, blowing a gasket, and all kinds of bad stuff.
Next time the needle starts to go toward the H, pull over and shut it off until it cools down. A hot engine could lock up forever within mere minutes after overheating by the pistons welding themselves to the cylinder walls.
overheating an engine is BAAAAAADDDD!!!!

You probably have a bad thermostat which is a relatively inexpensive repair. You might also have a malfuctioning water pump or your radiator could need flushing. At any rate don't drive it hot, have it towed to a mechanic so you don't burn the motor up.

This is something I dealt with before, it's pretty simple ready ? Flush that dam radiator out !!!! That's all it is, debri is gathering in your radiator and blocking air flow, it will cause it backflow sometime, forcing the coolant through the runoff tube. Try that and get back to me..

It could be a few different things. The easy and least expensive things to try is a thermostat. You could do major damage to the engine and/or head damage if you keep driving it overheated.

you could have a bad water pump that is not circulating the coolant, you might also have a thermostat that is not opening to allow the coolant past.
