My bottom radiator hose has a leak and i was wondering if there is a good way to go about replacing it as far as making the process easy? Any advice will help.

#1 Drain coolant.
#2 Remove or slide clamps.
#3 remove and replace hose.
#4 reinstall or slide clamps back to proper position.
#5 refill and bleed cooling system.
#6 start engine, inspect for leaks and proper installation.

If there is another way please chime in.

"easy" but more work....

Remove passenger inner fender well. Drain coolant from drain plug at lower passenger side of radiator. Leave the radiator cap on and it will be a slow drain - less mess. While coolant is draining pull the fan and shroud off. This will allow super easy access to the water pump to hose clamp. You can loosen that. Remove hose to radiator connection (clamp is stuck to hose so they come off together) Remove hose to reservoir connection. Then pull the hose off the water pump and yank her out. Reverse the process for installation. Fill up coolant reservoir with your mixture of dexcool. test drive and top off. may take 2 test drives to get it properly full.

If your coolant light comes on then you topit off and it stays on, cycle the key. If it is still on turn the key off and bang on the cap of your reservoir. Light should now go out.

I doubt it is the hose-- more likely the water pump. Lower hoses rarely leak. :D

No it is for sure the hose. has a split on one of the smaller hoses that branch off of the larger one.
