Average Coolant Temp and Oil Pressure
So what re you guys running as far as temp and oil pressure. I just swapped my cluster and was just trying to figure out if my temperature especially is average.
Its summer and I live in Florida and always have the air on Max.
Average in town no highway: 215
Average highway: 220-225
Immediatly after getting of the highway: 235-240. It usually doesnt touch 240 but if it does it is only for a second.
City driving after highway: 220
Oil Pressure:
60 on cold startup
30 at idle
35-40 in town not idleing
40-50 highway
Just wondering if these are about average. The only thing I am somewhat concerned about is the temperature. I have replaced basically everything in the cooling system except the radiator and overflow bottle. Literally, Everything, So am I still running marginally hot or is that about average.

Mine is constantly at 210 on the gauge. Doesn't matter whether I'm on the highway or in the city.
My oil pressure is pretty much the same as yours.

Mine runs, atleast 30-40 degrees cooler, than all of yours....???

Oil pressure for mine is at the first 1/4 marking at operating temp.

what have you upgraded or changed in your cooling system to make it run so cool? cuz wouldnt 30-40 degrees cooler mean your consistantly running about 180-200 tops?

I bet if you took your radiator apart, youd see 80% or more of the coolant rows clogged. Ive seen only 7 or 8 lines that could flow out of near 100 lines(2 core). with the symptoms youve described, rod that radiator out, or get a NEW one. Also the crappy plastic cap on your fill bottle should be checked for tightness.

I'm usually crusing around 210 maybe 200, california 100 degree summer in full force right now though. I'll see what fall/winter brings. My oil pressure jumps between 35-45
