69 GMC radiator question
 

Took the truck for a ride and notice after few minutes on the parking lot , that was water leaking from the radiator ( the hose conected to the top )

open the cap and really the water is there,,,maybe 2 inches under the cap

Any idea?
The engine did not over heat

is that normal ?

If its leaking, its not normal. Id replace the radiator hose and see if that doesnt help. It may not be overheating now, but you dont want to be stuck in traffic on a hot day with a blown hose or water pump.

That's normal. It finds it's own level. Enough for expansion.

well the radiators look fine
not even getting hot,,,

Re: 69 GMC radiator question
 

it is normal, the fluid only needs to cover +1" over the coils in most cases. a little expansion room is good. also condensation will come out of the overflow tube if real cold or hot outside.

Thank you
was running dripping for maybe 5 minutes,,,enough to make a mark on the driveway
could say a good beer cup
will keep eye on

Re: 69 GMC radiator question
 

When it finally stops dripping check and see what the level is. Keep it full to that point.

Good looking GMC!

If it bothers you it is easy enough to install an overflow tank. As has been mentioned it is normal for the radiator to spit some fluid out if it is over filled.
