leaking radiator fluid

[plugger]

I have a '98 Explorer that is leaking radiator fluid. I appears to be leaking between the resovvoir and the radiator. Is this a busted hose?

Leaking coolant is pretty much a gravity thing follow the trail upward.

The hose from the radiator cap to the reservoir stretches and leaks at the connections.

Also the crimps on the radiators get funny in cold weather and leak.

Finally the bottom hose can leak at the fittings if it is old or clamped too tight.
This is in addition to the obvious hose splits.

Get on your back with a flashlight, under the car and look for a trail.

Another thing to do is to connect a cooling system pressure tester.
