High coolant and engine oil temperatures normal? D12 Volvo 630

Normal for 07 D12 i was worried about this too when i first got my 07 but yes it is very normal i have the same numbers

 

I know I'm a little late on this but. My temp shows 172 or so. I have my egr crossover tube blocked in the front of the motor. No hot exhuast gases back in to motor. I'm looking for a hotter thermostat now.

 

your munbers are about the same as my 2006 d12

 

mine 06 D12D 465HP during normal driving oil temp is 210.. up long hills it gets up to 220 but rarely.. now in the winter is around 200-205.. coolant is around 180-190 most of times

 

Normal, cooland 188/195 oil 205/220 on Hill climbing .....!

 

I have a D12 volvo 780 model2005. Runs very well but coolant temp very low sometimes 128 degrees in winter. When it gets this low, AC/Heater wont give me heat!! when outside temp gets better like 50 coolant rises to b'tween150 to 160 but never gets to 170 except in real hot weather in summer. When I cover the front grill with cardboard it gets warmer and cab gets heat. Whet it shows too low on temp gauge on dash, I stop, open hood radiator cap and stick finger .....and I find coolant just warm, even after an upgrade hauling a regular ..like 30,000 lbs.
Anyone with an idea about such low temps,

 

change your thermostat.good luck.

 

Thanx QUALITY TRUCK. I'll give feedback here as soon as I have new thermostat fitted. Suggestion appreciated.
