Default 13 lb radaitor cap

Yeah I know, a simple 5 dollar part if you go to big box auto parts store.

BUT they are plain Jane and even the nearly 20 dollar one by Motorcraft says MEXICO on it.

Now there's a summit one available with a small zinc that looks too long and will bottom out in the expansion tank, Anyone use one? I'm guessing that it is grounded to the cap and sure couldn't hurt having one when running an aluminum radiator.

I have a really cool chromed Motorcraft but it is a brass seal on top, and will give up pressure when it feels like it.

What's a good one ? I don't need a stock one but prefer the proper look and not a Hecho en Mexico one.

I was given a dealy bob one Mr.Gasket with the temp dial inside. It's brass sensor would not touch the coolant level so I added a heavy copper wire with a touch of fixing solder, now I know why it free as it didn't work both ways.

Warren, just got back from driving my Tiger, so I can't take off the cap to see where it's made, but I've had this cap on my car for upteen years- never leaks, has a little pop-off valve (which also never leaks) which is handy if you have to do roadside cooling repairs and need to have a controlled release of pressure. I'm running a 16lb cap because my heater core is in retirement. Surely they make it in a 13lb cap...

Car cooled off so I took off the cap- nothing on the underside about country of origin, either. Must have had it on the box, long gone by now...

Default Do you feel lucky, Warren...do you?

I went to the Stant website and they say 85% of their radiator caps are made in the U.S.A.

Default Lever cap

I don't care for the lever caps and I have seen that they do come in 13 lb.
I run a stock heater core. As I understand the system is designed for that particular pressure and I have seen several heater cores where the sides have expanded. Sure the heater core also had significant cast iron stuck in it's rows.

I am mostly concerned with looks and a non lever cap. I kept a lever one in my spares kit but it's gone South. Not to Mexico but the boot lid will pop open sometimes on a stiff bump then leadfoot didn't hear it as it spilled in the roadway and nobody said hey hot rod your spilling your stuff
