I need help figuring out where my coolant is leaking out of in my 1988 3.9l dakota

. The coolant is pooling on top of the engine and I don't see a leak from any of the hoses. I haven't had any problems before with leaks but about a week ago I saw it was getting low so I filled the reservoir up and the radiator was still full but today I went to check on it and the reservoir and the radiator was both empty.

Rent a pressure tester.

Pressurize to 16PSI.

I'll bet that bypass hose, which looks cracked from here, has a small leak under pressure. For now; later it'll suddenly blow wide open.

ahem

Not that I'm saying that's happened to me ... but it did.

Also, dry it out completely.

Then take the cheapest foot powder you can find in a spray can, and spray it over that area.

That way, you can find the tell easier (by where it gets wet).
