Anti freeze odor (1 Viewer)

[EdsCruisin]

I've noticed over the past couple weeks a very weak steaming antifreeze odor when I get out of my truck. Problem is I can't find any wet spots. The overflow tank could use some additional fluid, but it's not totally dry.

Anybody have some ideas of weak spots to go looking for? I don't want to be on a road trip this summer with the camper and have a coolant blowout, especially inside the truck.

Pull the skid plates and check underneath. One good thing about Toyota Red coolant is it makes nice pink crusties where it leaks.

I have the same thing. I have a freeze plug leaking tiny amounts of anti-freeze. It is located at the rear of the engine block and can be seen from underneath by looking up over the transmission. Transmission has to be pulled to fix mine, so I will be adding anti-freeze when I need too, which I have not had to yet.

My radiator cap went weak. Only sign was small pink crusties under the edge of the cap. Replaced cap and my slow coolant leak was gone.
