I guess there are benefits to a high torque start (gear reduction) using less power, but at the same time I look at how reliable will it be? compared to a oem style

Did the V1 radar not work?
he wasn't using radar even though he put that he did on the ticket

I don't know, they've been around a long time, but not used as much obviously because you really only need them for high compression engines that are hard to turn over.

I found the 1.7 KW 11t starters when I searched for the 6.2L
Grabbed a Remy from RockAuto. We'll see how that works, and I guess I'll finish my big three and upgrade the starter wire at the same time.

All these factory starters are gear reduction also, they just use a planetary style reduction.

Have to park mine for a few days. My Mishimoto radiator is leaking in about 10 different spots. I can't even top off the coolant bottle without it leaking right back out. I bought this radiator as an open box special back when I replaced the engine a few years back. Basically it was discounted because it had some blemishes and I figured who cares, can't really see it anyhow. But the discounted price also meant no warranty. Fast forward to earlier this year, I noticed a small leak on the driver's side, near where the core welds into the tank. Now it's doing the same thing on the passenger side. I pulled my fans and noticed both sides of the radiator are leaking at a lot of the welds, in a bunch of different spots. There are leaks in the middle of the radiator too!!!

I'm torn in the decision I have to make. Do I blow $600 on a brand new Mishimoto that CAN be warrantied, or do I buy another brand. I'm going to be buying a procharger and installing it this upcoming spring, so I'm not confident that a factory radiator will be good enough.

I've never experienced any radiator leaks in any of my vehicles, ever (knock on wood)

I'm still rocking the OE radiator on both the 2001 and 2012.

Heck, the 2002 Mustang still has the OE radiator, and the 1995 I only replaced because of the much added HP and that was replaced with an OE replacement that had 2 cores instead of the factory single core.

Only vehicle I have with an aftermarket all aluminum radiator is the 1933 Ford. It has an Afco that cost about $900

How many vehicles come from the factory with 6-, 8-, or 900+ HP and have aluminum core rads with composite end tanks? See if you can contact anyone with a Hennessey or Lingenfelter GM SUV to see what radiator they have. Maybe browse a Challenger forum.

I'm just not a fan of being at the mercy of someone's TIG skills when reinventing the wheel. I think one of the reasons the OE-style aluminum and composite rad is so successful across so many platforms is because it can take the shocks, vibes and other loads experienced in a daily driven environment. The all-aluminum rads are too rigid so the weakest points are soon revealed.

As a happy owner of a Cold Case that's been in 3 years now, about 30K miles and (knock on wood) isn't leaking yet, I would STILL say go buy a Denso from Rock Auto. They're the OEM supplier and they're good radiators.

I finally swapped the front brakes on my 2009 Denali XL for a set of PowerStop Z23 rotors and pads.

Those rusty rotors needed a lot of elbow grease to come loose!

The drivers side rotor was warped and a stuck caliper pin may have been the culprit. Getting that stuck caliper pin out was REAL fun! After installing the Z23’s I noticed an immediate improvement in braking performance. I’m definitely looking forward to ordering a set for my rear brakes!

Picked up the lower hinge for the driver's door from the body shop after being painted. Wish I bought both hinges to save shop costs but I was fairly confident the upper will be fine for awhile.

They matched per the paint code and looks great, no more clacking when opening and no more sagging. Little tight to get to a couple bolts but went in fairly easily, just have to be certain it will clear the fender before you close the door for a test.

Hinge is a SKP

Part# SK961026

Was originally silver, sorry forgot the pic.

Just got back from another trip to OKC. I swear that whenever I park the moho anywhere near the Denali, its size makes her look like a geo cruiser.
The trip went well, traffic wasn’t too bad and we were able to avoid some interstate parking lots. The wife took home a reserve world championship trophy, so she’s happy. I’m just glad to finally be back home…minus the weather.

So what have I missed?
