i have a coolant leak somewhere. the reserve is fine but it completely drains ou on 1999 Chevrolet Tahoe

drains from normal area to fill. staying in the reserve. there is a clamp loose but not sure if that is the real issue. need to know where and cost
and what it may be

Asked by for the 1999 Chevrolet Tahoe
Agree with answer 1. Cost depends on where the leak is and how long it takes a mechanic to find it!! It will have to be seen to determine that. Any repair shop can do this.

maybe you have a coolant leak right? you should have it pressure checked to find the leak first
where? and what is the usual cost for that?
U could actually go but ur own pressure test from the auto party store and save money... It could be something as small as a plastic coupling or it could be a water pump...
