Check the lines all the way to the ago heater, appropriate behind the behind passanger wheel. 2 lines room refrigerant for ac, the other 2 room coolant lines because that the heater. My wife had actually a tire detread itself and also rip the coolant currently off pouring coolant on the exhaust.... She assumed the truck was on fire. I bypassed this lines and i am not resolving them at all. There is a u shame rubber bypass hose simply for doing this. The proper way to bypass the is in the engine compartment however i did that under the truck while top top the side of the roadway with piece i hacked off the lines. Ns do have actually the bypass hose however my roadside resolve is solid. Gates makes this hose and also its under $10
usedkornkid,If you have actually a coolant leak, what general location is the swimming pool of coolant?Here are some hose diagrams because that you to walk by.
Heater hose t-junctions are easy to watch along passenger side and prone to leaking. Another culprit is the connector to intake on passenger rear corner. This one is a little harder come see. Having a mirror helps. Freeze plugs are a pain, and cannot be viewed at source, however there are tell-tale places where it will pool underneath, such together bell-housing bolt.

Thank you. I ended up figuring that out. It was the upper and also lower manifold gaskets. Acquired them replaced, and also no more leaking!
I had a leak when that to be at the water pump would spray a teenie tinnie bit where it would certainly evaporate and you might not find or check out the leak, however the coolant would disappear. Then someday I experienced one drip. And chased it back to the water pump.Just saying, glad you discovered the issue.
