OK, I'll start from the begining. I was driving the truck home, looked down and noticed the temp gauge was going up...shifted in N and coasted to a stop. Turned the truck off, got out, looked and everything looked OK. Got back in after 5 minutes, started truck...temp gauge went back to normal. Started down the road, no A/C, radio off, and went about 1/2 mile and the temp gauge rocketed back to HOT...shifted into N and coasted to a stop, turned the truck off and got out again and didn't see anything--no leaks, no hissing, etc. A gentleman pulled over and offered his help...put maybe 1/2 gallon of water into the overflow tank. Waited about 15 minutes this time and limped her back home (3-4 miles) with no issues.
Went out the next AM to warm up the truck, came back out after 5 minutes or so and there was a small (a foot or so) puddle under the radiator. Turned it off and drove the Crown Vic (1999 retired cop car). The radiator continued to leak for 3-4 days, but I couldn't see where it was leaking from. So, today I went out and poured some filtered water in (going to do a flush before I refill) and waited for the leak...the bottom of the radiator (looks like a tray the radiator sits in) filled up and began to leak...Hoses are fine--no leaks that I can see......
Here are my questions:
1-Any ideas as to where the leak is coming from? (other than the radiator
2-Has anyone used a radiator leak additive in a 6.0??? I used to use one that comes in a tube about 4" long and an inch in diameter and it was filled with what looked like silver metallic shaving, maybe 1/16" in size. Is this stuff safe for our trucks?
Sorry so long and TIA for any and all replies!
