Ran hot, now stuff breaking

My 1 year old Taurus fan crapped out on Monday, ran it up to about 240ish. Never hit the red zone. Now with the clutch fan installed and the temp under control, my Napa radiator blew out, Im guessing its from the extra heat the other day... I have a new Rad ordered from radiator express, but in the meantime, should I replace the water pump again? Its only a couple months old.

240-ish temp shouldn't have hurt it. A 17 year old radiator giving out isn't a surprise, but if the water pump is only a few months old I wouldn't replace it unless there's some indication that it's bad.

The radiator was just over a year old.

Sounds to me like you had a defective radiator or a faulty cap. The cap should have opened when it got that hot to let the pressure out rather than blowing out the rad. Or like said before the rad could have just been defective. You should also replace your cap when you get another rad.

I wouldn't think the new water pump would need replaced and they're designed to take the heat.

There's a thread floating around here which believe is from AVR2 with a Chrysler statement saying if the temps get up into either the 220-230 or 220-240 range it's not overheating. Granted yours was definitely overheating with no rad fan but since it wasn't in the red believe the water pump should still be fine. Good luck.

NAPA radiators have a lifetime warranty, just FYI.

True, but no reciept, no service. Plus who wants another sub par radiator and to go through this again later? It appeared that the leak happened in the usual spot, driver side at the crimp. I need a two row for this anyway. The Napa 1 row just isn't good enough. I do have a Mark VIII fan on its way, that should help alot since the Taurus fan blade and shroud is smaller.

The cap is 2 years old and it did its job. Coolant spilled out of the overflow tank each time it ran hot making a nice big mess.

Hopefully the heads are ok. Have yet to check the oil since this happened

You have a bad Napa store then. A lot will argue the point, but if they know you, or heck even look back in their records for that part number, you can still make a warranty claim and get your money back.
