Engine temps (1 Viewer)

[lastresort576]

Just curious what you guys in 80’s are hitting for engine temps these hot days?
Moving, stopped, hwy?

Also what’s your cooling system setup? ie blue fan clutch, fan clutch mod, radiator? Etc?

I’ll be doing a coolant flush in a few days..last time was about 3yrs ago with red. ..but I’m trying to figure out if I have an issue with my cooling system or not before I leave for Colorado with a camping trailer in tow. Without trailer I’m around 188-195 driving which seems ok..but stopped im around that 205 mark.
I’m oe cooling system with a 1yr old blue hub fan clutch. It almost feel like it doesn’t have as much resistance as it did/should but I could just be in my head.

I’m no expert but those temps seem pretty normal to me esp if the outside temps are hot. Also, I wanted to mention the wind direction does play a part in cooling when stationary given the relatively low speed of the fan compared to say a 5 knot wind breeze from the rear to front of vehicle.

For example, when I’m at the beach with a constant breeze, I’ll be right at 185 when I’m parked into the wind versus 10-15 degrees hotter when facing away, esp if ac is also running.

you could try comparing the spin resistance of ur fan clutch against others at one of the upcoming meetings where other 80 series will be there.. charlotte meet coming up

Wind direction actually makes a lot of sense. I hadn’t considered that.

I’m probably being overly paranoid since sinking the truck last month. But the other part of me has me thinking if it’s this hot at sea level what am I in for at 10k feet above.

you just reminded me to spray all the mud off my radiators; thank you

Those are normal temps. If you want it to be a little lower, you can put in a cooler thermostat. I can't remember if the stock one opens at ~180/ ~190.

also you may want to research adding on an additional electric fan - try searching the supercharged/turbocharged threads since those may run even hotter; I think you can pull them out of other used vehicles? crown victoria? I forget. if you find a good thread, please let me know. If it were easy enough I may be interested in adding an electric fan.

Pulled a trailer with my lx450 from nc to ca and back. I got to 203 when climbing grades. But for the most part my truck runs at 193 with or without a trailer. I love my scan gauge for this.
Doesn’t hurt to change the radiator fluid and thermostat before the trip. The fan mentioned above is something I have been wanting to do to mine for a long time.

If the temperature rises when stopped that generally indicates your fan clutch is the weak link. Not necessarily an issue since it sounds like you're not overheating. Mine runs cooler than that when stopped, but my fan clutch is modified.

The scan gauge definitely helps give some peace of mind. But also causes some stress too haha.

I think one of these days soon I’m going to add a 100-series fan over the condenser. I’m not entirely sure how it does it, but supposedly by making the ac system work easier, it helps the truck to run cooler as well.

Yeah I’m thinking I need to modify a fan clutch one of these days. Or get an upgraded radiator. I currently have a rock auto Denso…which seems to work ok but an aluminum one might be a better way to go.

From what I’ve come across the ac condenser fan from a 100-series is the way to go. It doesn’t do much for engine cool per se..but it helps take strain off of the ac system which supposedly helps the engine to run a little cooler. And you can tap it into the ac trigger switch so it comes in automatically as well.

My truck ran 182* to 186* in all conditions. It spiked to 207* in deep sand and 90* temps at the Outer Banks before the supercharger. If you don't have a supercharger, I would recommend the TYC1918 radiator from RockAuto. It's much thicker than OEM and kept my truck at 184* everywhere I went with almost no fluctuation in temps. The Arizona Cruisers love them but unfortunately my supercharger did not and the fan blades cut the tubes. I now have a Denso radiator.

I’m still in CO, actually got back to my father in laws house last night from Moab. It’s hot in Moab and it’s hot in Denver..100’s out. I’ve definitely been struggling a bit with temps out here on this trip. Even after a new aisin blue fan clutch, sealing the fan shroud, and a coolant flush before heading west.

Highest I’ve hit was 223*. Most likely while towing. But still higher than it should be driving around Denver streets( no trailer). Turning off the AC and cranking the heat has kept me from a meltdown. So yay. But once I get home diving into this thing to make it cooler with out doing the fan clutch mod. I feel like it should be able to handle the heat without doing it.

The other issue I’m noticing is I feel like my fuel is boiling off and turning into condensation in the inside of the tank. I have replaced the charcoal canister but not the lines..yet.

Oh and my rear bumper has melted quite a bit. The tail pipe tip broke off on the move to nc last year and the exhaust is just flowing straight back.

imo you need to mod the fan clutch. The stock blue hub fan is not that powerful. Increasing the amount of air flowing through the radiator massively increases the cooling capability of the whole system. If you have the clutch thermostat set correctly, it should only be really pulling air when you actually need it.
