    Well I know enough to know you know a great deal of these engines. That said, while not with hemis I have seen intake seats drop out because the head got hot, and the cool fuel coming in past the intake seat keeps it cool and when there is not a lot of press, the seat falls out.

    I appreciate the compliment, thanks.

    This is one of those things that the internet has emotionally latched onto and has developed legs of it's own (the act of reducing anxiety about valve seat failures :^)

    Well my car is stock right now, so I'm probably better off with the stock temp thermostat I guess...

    Finally got a call that the water pump is in!

    I need to decide tonight (so I can order it in time) whether to get an OEM Mopar (203* T-stat $46.43CDN!!! or 2x as much from the dealer!!!) or a Stant 48799 (190* Superstat $12.28), or a Stant 46792 (203* Superstat $12.25) :(

    If you're not going to alter fan on-temperature set points, stick with the 203F T-stat.

    So do you think I should go with the Mopar or Stant Superstat then?
    Thanks

    Stant would be fine; just ensure it is identical structure-wise to the OEM. That is to say, there is a backside extension / plate that redirects flow to warm the engine up quicker.

    I've been running a Stant SuperStat for 5 years now without issue. Can't say the same for Jet (didn't open at the proper temp during the boil test) and Motorad (was damaged out of the box). And Hemissary's correct, if you're not adjusting the fan settings via a tuning device then just stick with the stock 203F temp.

    I really like the superstat. Where I see it differ is it doesn't cycle alot.

    This hurts to read... I was hoping to kill two, maybe 3 birds with a new coolant setup, LOL! I did a major, time consuming flush of my entire system last summer and yes, typical crap came out of the 107K motor. Upgraded SRT radiator & hoses, regular RT hoses in the back, DORMAN 620039XD fan, 190 T-stat. My Magnum still hits 225 degrees when idling and stop and go traffic now and then, when ambient temps are above 60. I've been monitoring the dash for months, just to see how the new system is working. I'm ready to get the car tuned, so it peaks at 203 only. I'll buy a new fan and install it if my new one prematurely craps out.

    So I'm on RockAuto, seems like they have plenty of WP available. I went with a GMB last spring and it's still sitting in the box, my OEM spins just fine and the corrosion around the T-stat area was minimal.

    Do I have a Gen 1 or Gen 2 WP from 2006? Why do I ask, because I believe my WP has a drip from the backside, not the shaft area or T-stat area. I think the gasket is bad and RA has two variations available.

    Only one type of 5.7 / 6.1 water pump in 2006 model year.
