Engine Guarantee Tag

[TonkaJim]

Anyone know who puts these "guarantee" tags on their engines? It's just to the left of the oil pump. I'm trying to find out the builder of my recent purchase...

Thanks!

These are VERY common and will tell the builder that you overheated the engine.

The center melts.

I see this often based on where the engine comes from.. as they are a few builders/businesses in the Dallas area who use these..

Those tags are usually seen on water cooled stuff, but they've been around for more than 40 years. IIRC the center melts somewhere around 250F. We've argued the validity of them on ACVWs as they can hit 250 without being a problem.

Called a "heat tab"
About 50cents, and they all say that.
"warranty void" thing sounds threatening, but it doesn't mean there is or isn't a warranty.
more like it just gives a clue about the problem.... when the customer brings it back for the third time blown up. that guy is out there and you will meet him eventually.
might be worth 50cents or it might not.
If you are the anarchist type..... just put it in the glove box, and glue it back on with grey silicone after the engine is blown up.

Sounds like a great way to deny a warranty under any circumstances that happened to melt it

GEX used to use these.. may still use em?

Pull the shroud off and look for stamp markings on top of the case..

You can get them in a wide range of melt points. Its just an indium alloy button....bery similar to a fusible link used in sprinkler heads and fire door props.

very common. part of the "cover thine own ass" attitude so prevalent today. A few years back I was speaking with a service rep at Mercedes Benz about what a pain in the ass the front ground effects air deflectors were to take off just to do an oil change. He said the technicians don't take all that off. They suck the oil out topside. After that revelation, I bought me a Mityvac oil sucker. Probably one of the best tools for the money I ever bought. Those MB people didn't want to stand accused of not torquing someone's drain plug. And the subsequent law suit.

My local hero has put one of those on all of his rebuilds for like 35 years now.

He stands behind a warranty,
Unless some lazyass overheats the motor.

Pretty simple really,
And a great way to make sure that some dummy who fried their shit doesn't try to make a warranty claim they don't deserve.

I'm going to put a couple on my next motor as sort of a 'belt and suspenders' approach to keeping track of how hot the thing runs.


Anyone who has worked around these things knows all too well how many will treat their rebuild. Especially bus people.
It will go in with multiple intake air leaks, a lean carb, too much spark advance, half the tin missing, no gauges and a clogged oil cooler.
They will leave the break-in oil in it, never touching the valves, loaded to the gills with four friends and all of their camping gear.
From that point, they leave their foot flat on the floor, in the left lane at 75 all the way to Truckee.

Then come back for a warranty motor at builder's expense...

CYA, man.

Tell me about the better way you keep track of how your customers treat their rebuild.

yeah but they all say that. I would leave them blank personally, or just say melts at 250F or whatever.
You put any word or number on a part and people think it means something, it's a heat tab. What's it mean? it means it's a heat tab.

[volksworld]

the ones GEX used to use were just round...if you rotate that one 90 degrees it's the shape of a V8....red silicone on the pump gaskets and no sealing nuts isnt a particularlly good sign
