Question about Cars & Trucks
I noticed there was no coolant in my reservoir so I put some in three days ago. The next day, the level was lower and I noticed antifreeze under my truck. Reservoir tank is empty now, but when I take rad cap off, the radiator appears to be full. Only leaks when engine is hot.
Start engine until get hot enough for coolant get hot pressurize then turn off engine check for leaking coolant hose.

i had the same thing on my wifes 2000 mpv van...the ends of the radiator are made of some sort of composite type material....it had a slight crack in it....wasn't obvious until it got worse and started streaming water from it when warmed up....even after it cooled enough not to be spewing it was hard to actually see the crack though a few inches long....was hard to even see where the water and antifreeze mixture was coming from until i took out the radiator

you must drain air out of system
so when engine is warmed up, just unscrew slightly the thermo time switch which is the highest sensor and unit in cooling system besides the reservoir, until alittle air releases then when antifreeze starts coming out then retighten to specs. BE VERY CAREFUL !!!! LOOSEN VERY SLOWLY AND NOT COMPLETELY REMOVE FOR THIS CAN CAUSE BURNS. MIGHT WANT TO USE A RAG AROUND SENSOR. If this doesnt solve it then make sure you have the correct rad. cap. Also that the filling hose is not clogged as well as the little port on radiator.

The problem is most likely 90% head gaskets but could be intake manifold gasket leaking too. Intake gasket has to be checked when intake is removed. Might find problem there if not continue and remove heads. Bars Leak will not work.
