Trying to get an idea as to where I am losing coolant. Leaking down where trans and engine come together on passenger side. I thought it might be heater core, but the lines are clearly visible at the top and they are not leaking. Any ideas or suggestions would be appreciated. If you think it may be the heater core and can provide me some by-pass info I would appreciate. It has many miles and Im not looking to spend to much, but I love it just the same. Especially NO PAYMENT. Thanks for the information.
