Heater Hose Leaking (replacement guide?)

Usually the hoses are held on my clamps, you remove the clamps on either end and remove the hose. You might have to remove parts to access the clamps/hose. You can search online for additional help and videos. Try a few Toyota owner forums and youtube.

I would advise that you take this to a good mechanic, because if it is just one hose that needs to be replaced, it shouldn't cost much- although the labor might run the bill up because you will want to replace all the coolant and pressure test the cooling system before you take it on the road again- this is a messy job, and can be dangerous for your engine if not done correctly- just spend the extra money, keep your hands clean, and get it done right- that is a valuable van-
