In the morning, or sometimes if parked for a few hours the gear selector lever will not move out of park until the engine has run for at leat 3 mins often 5mins....no good for a quick getaway.

It's a 2.8L engine. I'm not sure where to begin.

The two hose pipes connected to the radiator (both at the top and bottom of the radiator) randomly and abruptly disconnects from the radiator thereby making all the coolant to pour out.

This happens unexpectedly and within intervals of less than one hour.

Kindly advise why this is happening and what should be done to permanently stop it from recurring.
