Hi Guys,

I was wondering what sort of oil temps (with single oem oil coolers) you guys see as compared to your coolant temps. I have a fluidyne radiator. Once the entire system is fully warmed up, I normally see oil temps staying about 20 degrees hotter than my water temps. This reading is taken from the oil pan. I'm wondering if this is about what the rest of you are seeing?

Thanks, Adam

My sending unit is mounted in a RE-SPEED oil filter pedestal. During normal city driving, my oil temp gauge reads similar to my water temp gauge. Out on the track, 20-30+ degrees difference and would go much higher if I didn't lift and short shift.

An odd thing is that if I sit still and rev my engine, even w/o a load, oil temps quickly rise 15-20 degrees. I suspect it has to do with the oil cooler quickly "heatsoaking" and not being able to sufficiently cool the larger volume of oil. Maybe I'll break out the IR thermometer to see if that's the case.

Thanks for posting your info. Maybe I should take a look at my oil cooler to make sure nothing is preventing proper cooling.

Keep in mind, I'm taking my reading after the oil cooler and yours is basically right after it comes out of the engine. I don't know what my oil pan temps are or how they compare to water temps.

Pedestal is right before the cooler.

No. Oil is pumped from the oil pan to the oil cooler, then flows to the filter/pedestal assembly. Oil temp readings at the pedestal will always be cooler than the readings at the pan

The single cooler was a joke for these cars. not only is that single cooler not particularly efficient, its also small, and the FD runs extremely hot. Why they felt it was necissary to only have one for the base/touring model is beyond me but they also had a half inch thick radiator with plastic end tanks as stock

There's nothing wrong with a single cooler for twins and street use. If you go to the track, that's a different story.

To be honest, my (mostly) stock base 94 is much happier with the twin coolers, than the old single with bent fins but I could have other cooling issues going on. Basically it just takes load off the rest of the cooling system. I don't know about everyone else but my stock FD runs hot as S*@# (especially with all the stock junk packed in the engine bay)

So waht did your oil temperatures run with the single cooler?

Define runs happier? Fans run like they always do which theres nothing wrong with that. Hotter temps makes for better fuel economy and a cleaner/smoother burn. I notice zero difference on cars with single coolers when tuning them on the street. On near stock setups that never see track use, I see no need for duals unless the fins are bent to **** which a lot of them are I agree but healthy single cooler does the required job just fine. So often the case people just get duals to replace their bent to **** single.

Don't get me wrong, I run a dual 25 row oil cooler setup but thats because I actually need it for track use. My other black car is just fine with its single cooler and stock twins.

fans turn on MUCH later, the car runs much cooler overall. underhood temps *seem* cooler as well. Now, I guess I should define street use, I frequent "back roads" often, and with a fast uphill climb (especially when it was hot) I would have severe overheating problems to the point where I would have to pull over and pop the hood for 10 minutes or so with the fans running. Problem solved now with the second cooler and I made no other modifications. I guess if you drive like a grandmother you're all set with the one cooler and stock radiator True story, there is actually an older lady (mid 60's ) down the block from me that has an auto FD (94 montego, touring package... our cars match, and we chat every week or so, cool lady). She's owned it since 94, original owner. She babies the car and does all the scheduled maintanence and doesnt get into the turbos really (I've seen her drive on the highway, slow lane, cruisin slow, lovin life). She thinks the car is sporty, and sexy looking She's still on her original motor, oil cooler, radiator, and AST. Like I said, if you don't drive hard, you're all set

I have a Koyo radiator and my oil temp sensor is mounted in a RE-Speed pedestal. Cruising on the highway I see water temps pretty solid between 180-188° F. Oil temp stays between 170-180*° F. If I get stuck in traffic water temp will go up to ~194° F with oil temps going up to between 200-220° F.
