Cooling system failures
The cooling systems on the 6.2 and 6.5 trucks of the 90's came with aluminum radiators that were fitted with plastic tanks.
These usually have a fairly good life span but the tank seals do fail as do the fittings.
It's not all the rare to see one of hose connections snap off.
The upper radiator fiitting is the usual suspect.
This can start out very subtle anad just weep some or it can fail all at once and dump coolant everywhere.
Here is the radiator from my 94 Burb that has failed in such a manner.
This is likely the original radiator at 270K miles and it was caught before it failed totally.
The plastic degrades over time with heat and the flexing from normal opperation
This one manifested itself as a small puddle on the ground and what apeared as a leaking tank seal.
Upon removing the old radiator the broken fitting presented itself
