Hi guys,
Over the last few weeks I've been keeping my eye on my temps and I'm not sure if it's normal or not but I'm running around 90-95c which is around 200F, this is my normal operating temperature. It takes around 10-15minutes to get to this temp. I've done my research and most guys are running around 170, that's where I'D like to be!! To be honest, I never really paid THAT much attention to my temps or what was "normal". Having a ill fitting hardpipe (too long) recently let loose and sending my temps above 105c (the next line after 90 and it was climbing) due to rad fluids lost, antifreeze everywhere, heat/steam, what a mess. After that, it has me a little paranoid. Everytime I see my needle flick even a mm above 90 I watch it like a hawk.......it's taking the fun away from driving it being so paranoid lol. I have all the bolt on mods including Roe Racings 170 t-stat and Roes SCT tune. Still, my truck runs around 200F. I asked Sean why it would still be doing that and is there anyway to turn my fan on sooner? His response:
"Carl, 190-200 is normal in low speed driving and idle where the fan is having to work. I will explain how all this works.
1. When driving down the road, the air flows through the radiator at a rate faster than the fan pulls unless you really crank the fan up.
Your fan activates only when it gets above the preset point.
2. We spent time on the dyno and confirmed that we could lose up to 20 HP by driving the fan earlier and harder.
3. We determined an optimum point of temperature and fan activation point for the best HP and temperature.
4. If you want it on earlier, we can certainly do that for you, but it will be counter productive.
"
Now, I know Sean is the man at what he does so I'm not going to question is knowledge but I thought I should put it out here anyway. Is what he's saying true? I'd LOVE to look down at my gauge and see it sitting around 75c (170F) all the time. My oil pressure usually sits around 400-500 kpa (55-70psi). I'm looking at getting an external oil cooler with lifetime braided lines for safety to help take temps down. I also notice that if what Roe is saying is correct, then what about heat soak? If the fan is delayed and only comes on late, when I get on it/WOT from a cruising speed, the heat is full on and the performance lags. Any input is appreciated.
Cheers,
Carl
