260 at idle, why? I don't get it, the car never overheats cruising around, at the track, while corner carving, etc. Tonight I'm trying to charge my A/C and it got up to 260? Makes no sense, I saw the temp slowly climbing as I kept checking it, then the high speed fan kicked on. So I thought no problem. Well next time I look its in the infamous red zone, so I shut it down. Is it normal for it to get that hot idling in the driveway? Probably was around 10 minutes as I was fighting with the stupid hose you can get at the parts store to charge the A/C with, I got maybe half a can in and got the compressor to kick on. Then I saw the temp gauge and shut it down.
It makes 353rwhp and is 11:1 compression, does it really generate that much heat maybe while idling for a long time? The factory stuff can't keep up at a idle for a period of time? Radiator is a new GM unit that is under a year old, this car never gets over 180, I just don't understand it. Any potential issues with it running that hot at idle for a minute or two? I didn't seem to have any boiling coolant either.

Like said above, t-stat, bleed the system, and flush it. Also if the fans are comming on make sure they are wired/installed the right way, with the highspeed on it shouldn't ever increase in temperature.
Does it only do it with the a/c switched on?

BTW, I figure you know this already, but sitting in idle actually doesn't push that much coolant around. That's why Stop-and-Go can be hard on a car and fuel economy. Not just for being on and off the gas, but because it's so hot and it becomes inefficient. Electric fans really help this though, but with the low RPMs a motor still won't push a lot of coolant. One nice benefit of the EWP

Alright, no air in system, 170 thermostat, yes its tuned for it, yes low speed fans then high speed fans came on. I don't know, I was just trying to fill my A/C system after installing a compressor. Drove it today, never got over 170-180. So this just occurred at idle yesterday while screwing with the A/C.

If its a stopped up radiator why did it only occur then? Formula350s response seems logical. Ironoutlaw, any reasoning on stopped up radiator?
It didn't get hot at all with no A/C on at the track slowly creeping through staging lanes, or at all while driving it yesterday. Just while idling for about 10-15 minutes while I fought with recharging it. I went and got a longer hose setup yesterday, I had it all taken care of in about 5 minutes.

Coolant level is full, it's been about 8 months since I finished the motor swap.
I guess people are missing it, it hasn't ran hot since the bleeding and filling of the system back in August. It has only ran hot this once, idling in the driveway, sorry if this post comes off sounding pissed off, but.....

Speaking of which, I need to see how my coolant is after sitting 1/2 a year!
