Oh, jeez. This happens to you guys too? I thought I was just getting old and senile (which I am). I've driven for months with tools left under the hood. LOL

I've resorted to keeping a cardboard box in which I put all the tools as I'm working.

 

I found a pair of vice grips under the hood of a truck I bought once. They looked like they had been there for 20 years.

 

Funny story, towing to Tulsa for a race a couple weeks ago in the duramax, the lower radiator hose blew off the water pump.

It didn't break.

The clamp was still tight.

But the hose was off the water pump.

It drained all 5 gallons of coolant in about a half mile.

Luckily we had 4 gallons of water, and of course tools to put the hose back on.

But the worm clamp was still tight. Had to loosen it substantially to slide it over the pump, then re-tighten it.

 

Having to replace a Duramax engine would ruin your day.

 

Sounds like the clamp was put on the wrong side of the ridge on the water pump then, but how does that happen anyway since the rad to pump hose is the suction side? Gonna guess it happened after you'd been driving a bit, then let off the throttle? A surge is the only thing I can think that would cause that hose to pop off. Usually the only problem the lower hose has it gets weak enough that the water pump suction can collapse it.

 

It's been a year since we changed the WP. We were going 70 down the highway when dad saw water/steam coming out under the truck

 

Well, I was losing coolant again, so I went and rented the pressure tester... again. Whaddya know? It was leaking right at this spring clamp. It wouldn't leak while idling, so I imagine it was doing it at highway speeds, when the water pressure would be higher. Took my butt to O'Reillys and got a few screw clamps after talking all that crap about them. LOL

Pressure tested again and all is good.

 

I know spring clamps are what the manuals and the factory say to use. I always called them "Airplane clamps" as once you get them off, you send them flying. As for lost tools, the little gremlins hit here too. I've even been POSITIVE I laid a tool on the bench only to find it in my pocket later. I've never had an issue with screw clamps but I don't honk them down as tight as possible either. I go with the "Gudentite" rating.

 

The thing with spring clamps, as I said before... you have to get the right size... and they vary... even those that claim to be the same size. The hose I got was skinner than Mopar hose too...so it all contributed to being too loose.

 

That one with the spring clamp, looks like the clamp is on the wrong side of the ridge on the metal side since it can be seen. I'd suggest putting the hose past that ridge with the clamp on the other side.
