A bad radiator is a radiator that is leaking or clogged. If you are loosing coolant then you have a leak that should be easy to find if the leak is at the radiator. If it is clogged your engine will overheat.
assuming you have no water in the radiator. there can be several causes for this. one is the radiator has a hole, the water pump bushing is bad and leaking, you have a cracked block or head, or you have a blown or rusted through freeze plug, or your heater core could be leaking as well. or a hose has a hole in it. fill it up and see if you can find any leaks. if there is water in the radiator. it can be a bad thermostat, bad water pump, cracked head or blown head gasket.
You may have a bad radiator cap.
There are a lot of reasons why your cars is leaking coolant , some can be a bad water pump, a bad upper radiator hose or a lower or it can be a bad radiator it self , is can be bad head gasket,or your radiator is not holding Enough PSI the normal range is 8-14. so i hoped i help the best i could.
Several possibilities: 1. Radiator is leaking. 2. Coolant hose is leaking. 3. Hose clamp is loose. 3. Seal on water pump is leaking. 4. Overflow container is leaking. 5. Radiator clamp is loose or bad. Two highest possibilities: Radiator or hose is leaking.
Bad radiator fan motor; bad radiator fan relay; clogged radiator; thermostat stuck closed; loose belt; bad water pump; hoses leaking;
bad radiator cap
could be a cracked radiator, bad radiator cap, a busted radiator or heater hose, bad heater core, or a busted fill box!
either your radiator is leaking,head gaskit is leaking if it's your head gaskit leaking you will have water in your oil or water coming out your exhaust pipe,or you might have a freeze plug going bad.
Radiators do not have exhaust.
A couple of reasons, faulty waterpump, leaky radiator, bad hose, bad radiator cap, thermostat housing.
if it leaks on left side of engine at hose,could be a bad water pump! on 3.1 engine. if pump is bad it will leak out of releif hole on bottom of pump!
From easiest to hardest: Does radiator have enough coolant? Is the fan working? Could be a bad thermostat. Water pump (there is a small hole in the bottom of the water pump. If there is water dripping out of the "weep" hole, then the water pump is bad). Could be a blown head gasket. (Is there any water in the oil or does the coolant in the radiator have a fuel smell?
It could be a number of things, a clogged radiator,bad thermostat,low coolant, hoses leaking coolant, radiator fan not working,or a leaking head gasket. Hope this helps you.
A bad or incorrect radiator cap.
bad hose like a pin hole or bad clamp
bad hose, radiator leak, leaking into engine.
When the water pump goes bad it can leak coolant. Coolant loss can also be caused by bad hoses, a bad radiator, or a hole in a freeze plug.
besides making a sqeeling noise , or leaking from the weep hole , you can wait until the thermostat is open ( top radiator hose will be HOT ) and squeeze the top radiator hose , when you stop squeezing the hose if there is no surge of coolant flowing through the hose then your water pump is not actually circulating your coolant and has a bad impeller inside the water pump
Noisy, leaking from the weep hole on the bottom of the pump, or engine overheating.
Bad head gasket? Bad thermostat? Defective radiator cap?
Water leaking at the plug, radiator fluid level going down too fast.
Intake manifold gasket leak....big problem with that engine. Sorry for the bad news.
water pump seal bad
There are several reason why a car might lose antifreeze. The water pump might be bad, one of the radiator hoses could be leaking, the radiator could have a leak, a freeze plug could be leaking, or it could have a blown head gasket.
