Guesses are around 15-16 psi. seems a little high. Should I put the 13psi cap on this? I bought it a couple weeks ago thinking the cap was leaking.

Most of the modern systems run the 15-16 lb cap. Remember that anti boiling is affected by the system pressure.

We've used jb weld on just about everything on the farm from propane tanks to the hydrants by the barn and chicken coop when they froze and split open this winter. Never another leak. I've even seen in weld used on engine blocks, cylinder walls, and gas tanks with success.

Yes, Bill. I have used JB successfully on many things, I think the most extreme is on a mower deck mandrel area, and still holding. I was real surprised that the radiator continued to leak.

Jw weld and antifreeze do not seem to mix according to Google search.

Sucks it didnt work but your failure has saved us time.

I was installing a radio into a "pipe chaser" Utility truck that had a large water pump. the guage was marked in psi and bar. I was supprised to see 1000psi was around 69 bar. I guess I could have googled it. One concern, the Heater core close to 20 years old, you think I should get a lower psi radaitor cap?

The only 2 times I've used JB Weld on a radiator...both miserable failures.  The JB more or less turned to soft goo after a few days.

I wouldn't stress that factory is like 14.5 PSI we install those aftermarket rads all the time in those body style camrys and we just use the caps that come with them with no issues at all.

Larry, as JohnWR said earlier , don't sweat it , that little bit of pressure difference shouldn't make a difference. . Now if it were a 5-10 psi difference.. That could be an issue for all the old hoses ? But I still think the heater core would be fine.. If it was a Chevy..... I would be nervous... J/K Chevy guys I was a gm tech for many years ;-)
