Default vanishing coolant

hey everyone
i have a 95 chevy 6.5 turbo diesel and the motor runs great but my coolant is vanishing.
i checked the block and there are no cracks anywhere and the oil is fine no coolant in my oil. it isnt burning it either. no white smoke or anything. but i can top it off in the morning and drive 200km and the low coolant light comes on.

any help would be great thanks guys

Head gaskets or water pump. Only real way is having the coolant system pressure tested.

the coolant system builds pressure. i popped the cap the other day when it was running and it blew the cap out of my hand.

With the cap off watch the reservoir for bubbles with the engine running-if you see bubbles it could be a cracked head or head gasket issue-cracked block can also happen at any time.

Start it cold and feel the upper rad hose. If it's hard, you've got a HG problem.
