I have leak - appears to be coolant. Car has not been driven in couple of months. No lights have come on. Has been suggested might be a hose at the bottome of the radiator.
How hard is it to replace the hose at the bottom of the radiator? How expensive?
A pressure test of the system will verify the leak. Hoses are not to bad to replace but sometime they can cause frustration because the upper hose clamp on the bottom is tough to get to.
If you determine you need to change the hose, you will need to drain the coolant and one way to do that is to loosen the hose at the bottom and collect the coolant in a drain pan. When the coolant is drained, replace the hose, put the coolant into the top of the radiator, bleed the system of any air and you're done. A hose should be under $15 and may be as little as $5 depending on what your auto parts store stocks.
