Hey all... I rec'd my Outlaw CAI this afternoon and installed it. Took the truck out for a drive and noticed @ higher mph it would shake a little bit. Kinda like the pcm was pulling timing, or not allowing enough... Or possibly not compensating for the little extra air going into the intake. Then I glanced at my gauges and my coolant temp was barely above 160*. It's an '05 w/ a stock t-stat.... Stock everything really. Doesn't even have 3k miles. The truck was warm enough as I'd been driving it for 10 minutes. I got back home and killed it. Put the key in the off position, then switched it back to on.. The gauge needle then rose to 210* like normal, so I went ahead and started it. Again, it went to 210*.. And about 4 seconds later.. dropped back down to 160*.

Long story made short.. I'm much more familiar w/ LT1's vs. LS1's. The LT1's use two coolant sensors - one on the water pump that feeds the coolant temp info. to the pcm. The other is on the driver's side head, and it sends a temp. signal to the gauge cluster.

I'm guessing.. Err.. Hoping the LS1 cars use just 1 for both? Is this a common problem, or has anyone else experienced this? This sucks! I sure hope it's not a sign of things to come .

I guess on a good note it should be covered under warranty. Heh.

 

havent heard anything on that yet, not sure on the 1 or 2 temp thing, I think the one in the head is the only one, I'll have to look at some wiring diagrams....

 

Well.. I was right. . There is only the one sensor. And it sends the temp. signal to both the pcm and gauge cluster. It decided to actually work yesterday on the way to the dealership.... and they couldn't duplicate the problem.

Oh well. I'll take it back when it happens again.
