Z/28 oil/water temps in normal driving - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Stephen12ZL1 · 02-14-2015, 06:51 PM

My car runs so cool in normal driving that it almost seems wrong. I know how all of the nervous nellies in here talk about a "160 thermstat" will make the car blow up and is unsafe...blah blah. Obviously, GM has determined that the Z/28 needs a lower temp thermostat to run cool enough for a track dedicated vehicle. My car runs at 169-176 water temp and 170-176 oil temp when the ambient is in the mid 40s. My ZL1 with a 160 thermostat and a larger radiator runs at 176-180 water temp and always 210 oil. So, what is everyone else seeing for there typical cruising water/oil temps?

bump...anyone else have any temp readings from their DIC?

Temps and weather have kept me from driving mine for a month or more now with no letup in the near future. I don't remember the numbers to be honest with you, sorry.

This. Not for another month or more would I have good numbers.

If I remember correctly, LS7 reads oil temps from the bottom of the dry sump's oil container, which is a relatively colder place than the oil pan. So oil temp might read a bit lower, but coolant temp is puzzling. I wouldn't think GM can pass emissions with a low temp coolant thermostat? Had you driven long enough when you checked for temps?

at least 50 miles and it read 169°-176° the whole time.

Drove today with ambient in the low 50's and the cruising water temp stays at 172 and oil was 176 max. Anyone actually drive their Z/28? Did GM do something for the '15 model year because of high water/oil temps at the track? My ZL1s oil temp is minimum 210 and on track days it would hit 310.

Your zl1 is supercharged...temp gonna be higher.

+1 and LS7 comes with dry sump. The engine oil temp is measured at the bottom of the dry sump tank, which also tends to be a cooler place than the actual sump of the engine.

At cruise the supercharger is doing nothing...of course under load the supercharger is pushing a lot of heat
