the other coolant compartment off to the left in front of the windshield wiper compartment, is always empty. I fill it up and i check it and its gone!! anyone got ideas, the radiator is fine.
Check under the car for drips. My cause was total destruction of nearly all gaskets. Also a year latter my coolant started to go down again but this time it was rad cap.
1. get it pressure tested
2. if there's no obvious leak, bleed the system (if there's any air in it it will always force all the coolant out the overflow)
go over all your radiator hoses and fell them for and crusty material around the hose and check all your hose clamps aswell
check that heater tap, it may look good, but could be leaking, they are very brittle break easy.
I didnt think mine leaked, but when i went to replace it, the hose lug was broken, but still sorta working
yeah my heater core is gone. will this affect it?
yes that will. Mine was also gone 2 years ago. leaked coolant like hell.
block up those hoses then, at the tap, take it out block em up, then water dont go in there.
Or u could change the heater core, but thats a mission
yeh got the core just gotta put it in
The radiator cap is probably the best place to start, if the spring is weakened with age then normal coolant temps will open it and blow the reserve out of the container. Good luck with the heater core, I've heard you can change it without pulling the whole dash if you make some mods to the hard pipes, ie cut them off close to the body of the core and fit heater hose to join up. Maybe someone else knows more about this?

I had a similar problem when I first bought my car, though I was loosing coolant due to loose hose clamps and the radiator cap was buggered. Like other people have mentioned go over all the hoses/connections with a torch, even better get it pressure tested at your mechanic..
