Oil Pressure:
- Warm engine, idle: 10-15 psi. Mine runs 12±1 psi
- Warm engine, cruising RPMs: high 30s, low 40s
- Cold engine, fast idle: Starts out high 30 or low 40s, but will fall as engine temps rise
- Get worried at: anything single-digit
- My sending unit location: in the turbo housing (Banks turbo, recommended Banks location)
Coolant Temperature:
- Cruising temp: High 180s to low 200s
- Idle temp: Should hover around 195° if you're running an OEM thermostat, but will fluctuate as the t-stat opens/closes
- Get worried at: anything over 230°, though temps like this should only be seen if you're really working her
- Pull over at: high 230s, low 240s.
- My sending unit location: The port in the head where the 'OVERTEMP' sending unit normally sits
Oil temp: No idea. Don't have that gauge (yet)
