thermostat problem perhaps? some advice please
Not to sure if this is an issue, but here it is. My 06 always runs coolant temps between 188-192 with oil temps being around 8-10 degrees higher.
That said yesterday and today coolant temps have not gone over 168-170 and oil temps are around 176-178 with a periodic spike to 12 degrees higher. The thing is it took over 30 min of driving just to get to these temps. I start driving the truck when temps hit 70. Is my thermostat stuck open and if so why would oil temps be so low also?
Any advice would be really appreciated. I plan on cleaning coolant system with restore and put in cat ec-1 coolant along with a coolant filter tomorrow and install egr delete kit on sat. debating whether I should get oil cooler or not.
Thanks for help guys or gals
