is the leak at the top of the radiator?if it leaks around a bolt then the radiator is probably cracked. alot of people mistake the drain as a bolt wich is located towards the bottom of the facing the engine.if this is the case then you probably have a drain that loosened up and all you do is tighten it back down.
If it is red or brown it is the transmission cooler (in the radiator) leaking. If it is milky white, internal engine oil leaking in to the cooling system, head gaskets.
Can be leaking from a hose not secured properly or a hole in the system.
leaking head gasket or improper fluid in cooling system
The radiator drain plug on a 1992 Ford Thunderbird is located on the bottom, left side of the radiator. It allows for the cooling system to be quickly drained during maintenance.
Is it leaking from the water pump or radiator? Is the system properly pressurized?
Orange liquid leaking from any vehicle is usually a sign of a leaking cooling system. If the location is in the front then it is likely an issue with the radiator.
the little gray box on top the a.c. compressor or by the radiator.
A leak in a coolant system can usually be fixed by replacing a hose. If the leak is at the end of the hose, a new clamp might be necessary. If the radiator is leaking, the radiator might need to be replaced.
Sometomes it is hard to get all of the oil out of the cooling system. However the place that replaced the engine should flush the cooling system until it is clean. Also if your car has an engine oil cooler , it could be the cooler in the radiator and not have been the engine in the first place.
The question is referring to pour in type cooling system sealers such as Stop-Leak. If the radiator itself is leaking Stop-Leak will likely come right out as it is designed for small seal and gasket sealing.
The water outlet, also called a petcock is located near the lowest point in the cooling system and is used to drain coolant from the engine. The petcock typically has wings, which are designed for better grip when turning the valve. If coolant is leaking from this point, it may be the petcock is partially opened and might need only to be closed completely to stop the leaking. The petcock is press-fitted into the bottom of the radiator. A leak around the petcock can be caused by a crack around the collar or a solder joint that has broken. Have a radiator shop pressure test the radiator to make sure there are no other problems with the radiator, such as other cracks. During a pressure test air is pumped into the radiator and then it is dunked into a water tank. Air bubbles escaping from the radiator indicate leak sites and will need to be repaired. --mark
The transmission cooler is built into the radiator, and the tubes on the cooler are leaking Trans. fluid into the engine coolant. Need to replace radiator.
