car insurance liability coverage

Weeks ago I bought the car hire and have comprehensive insurance Can I change my car liability insurance?
And if you still owe money the bank when I go to change
You should ALWAYS have full coverage for any vehicle, provided that is financed or leased. If not, the lease or financial institution will your car insurance by force, and add to your loan or lease payments. You can change when the car is paid. However, on a "lease" the car is never paid. If you always have a lease that will always have full coverage.
