is 212F considered ok ?

Can low temperatures also be bad?
My rx8 was reaching consistent temperatures up to 210F... I ended up buying an all aluminum radiator thinking it was the old radiators fault but temps remained the same. I then purchased a relay fan kit from rotaryperformance that activates both fans at full speed at around 180F. Now my problem is that temps might be a little to low :/ my temp gauges when cruising read around (178-185)F coolant & (165-180)F for oil temps.

The thermostat controls how low coolant temperature can go. So that coolant temp sounds fine.
Oil temp is in the right ballpark for cruising, but either way, there is nothing (advisable) you can do to change it. |

Lets also cover something that hasnt yet been said....
If I understand and follow correctly, you Kamal said you hadnt changed your thermostat. You JUST had your motor rebuilt. You shouldve replaced that thermostat when you went did the rebuild, especially since an older worn thermostat can stick and cause issues regulating engine temperature. Stop driving the car and replace the thermostat NOW. All the cooling mods in the world wont save your motor if your thermostat isnt operating properly and doesnt allow coolant to reach the radiator. I think all of us can agree on that. Let us know what you find after you replace that. |

Yes ... temps that are too low can be bad ..... hard to know where the cutoff line is ...but I reckon the guys at Mazda probably had more idea on this than anyone here .....

Actually, thicker oil can maintain higher oil temp.

Hi So i put foam around the top, right, and bottom of my rad, cooling low fan mod, and I'm still seeing high engine coolant temps with obd2. it's currently 89 degrees but 90's are the norm. New radiator and coolant bottle came with the car. New mishimoto fans. New cooling hoses 04 mt 6sp |
