2004-2007 Cadillac CTS-V General Discussion Discussion, engine oil cooler in Cadillac CTS-V Series Forum - 2004 - 2007; has anyone installed an engine oil cooler with headers? I have every adaptor and have not found one yet? I ...
I'd try a lower temp thermostat first. When I drove the C5 through snow this winter, cringe if you like, the radiator got clogged and froze up acrossed. Even with the fans cycling on at 225F the oil temps were right behind in the 220s. Normal cruise is 192-194F for coolant and 185 for oil. Could save you about $950!
has anyone installed an engine oil cooler with headers? I have every adaptor and have not found one yet? I want to go to one of the driving schools and would like this bit of insurance.
One thing to make sure is the computer has been reprogrammed by a dealer for the "Engine Oil Temperature Gauge Warning". My oil temps were reading off the chart at Heartland Park last month (about 105 degrees hotter then the water). Scared the crap out of me until (thanks to the gang out here) I found out about this:
The Caddy bulletin is:
ASI Resolution - Engine Oil Temperature Gauge Warning
(August 3, 2004)
This only shows up with sustained high speed or aggressive driving. If this corrects the issue, my oil temps at the track should be only slightly higher then the wate temps which at the track rarely climbed over 200 degrees.
Make sure when you do the oil change, you use Mobil-1!!!
Thanks but I allready have a 170 stat, and the LS7 likes the high RPMs so swiching gears is nice but when all the power is between 5k and 7k aint tom much gear left to grab. rad is fine, and I have the re-flash my temps are not high, 230 range. I just dont want the temps to be high.
It has been quite good actually, drives like stock till you step on it. latest et at the drag strip was a 12.6 at 119.2 babying it off the line.
