I would think that it's the last cylinder (#5), regardless of firing order.

Tell that to pretty much every Baja 1000 racer :rolleyes:

They currently have 45psi. I'm considering lowering them to 40psi, but the tire guy said that they would be squirrely at a lower pressure. We'll see. They're a bit harsh at 45.

Wooohooo! New shoes!

Friday I'll be pulling the trigger on mine. Going with 305/70r16 BFG KOs. I really liked my Michelin LTX's, but they6 don't make em anymore in the 285 or 305 size.

Watching, as I'm getting ready for new shoes on mine as well. I've had the Michelin LTX AT2 (285/75r16) on my Alpha since I bought it; have gotten about 60,000 miles on them and they have been great. Not too aggressive tread, but never lacked for traction when off-road, and are quiet and...

If the sensor is going bad/intermittent; then the system will turn the AC off as a safety default, since it doesn't know what temp the coolant is at.

I've kept track of every tank on my Alpha since I bought it 6+ years ago; I run almost exactly 15mpg, regardless of the type of driving; dirt, city, highway.

Good question. The air "hose" from the grille area to the battery cover looks kinda cool, but I really doubt it has much, if any, effect.

This should be a "sticky".

Yup, Jeepwalker gave a great list. I will clarify one point though; change out the POS battery terminals with a good set; Stingers, etc. Trust me on this. Regardless of how good they look/seem, just change them out. NOW! H3's are one of the most finicky vehicles I've ever known (I'm 60, so...

Only downside is that the washer spray only hits on one side of the blade, whereas the stock setup sprays on both sides.

All of us have found out that these H3s are extremely sensitive to voltage fluctuations. Good battery and aftermarket battery cable terminals are a MUST!

Keep in mind that the vents in the rear door are there for a reason; to allow flow-through ventilation. If I were to move/remove the spare and put a plate over the vent, I would install it with 1/4" thick spacers so as to not defeat the ventilation. BTW, your plate does look nice.

Great list of things to check. I live in SoCal and my '08 Alpha seldom gets above the 1/2 mark, even in the summer. Although you need to get an actual temp reading. I use the Torque app with an OBD dongle; rarely see over 205 degrees, usually at 195-200.

Nice. Where is that?

Hate intermittent problems!:mad:

Sadly, the only 4" lift WAS the Rancho, but it's no longer made/available (I believe there was also another brand back at the time, but it also is no longer available). Short of a SAS/SOA conversion, you're limited to cranking the torsions (to no more than 23.5" center of hub to fender lip)...
