yeah the shroud is all there, the fan is clutch, and it works fine, but it shouldn't make a difference on the highway doing 70MPH. one of the blades is bent, but otherwise...

quickest and safest way to cool an engine down
i'm just wondering what the quickest and safest way to cool an engine down is...
my thermostat is rated at 185F, but my temp gauge says closer to 210 when i'm on the highway for a while. i do have to put in a larger radiator, and change the oil for heavier stuff (still the winter weight) so from 10W30 to the usual summer 20W50.
so more or less i was thinking like when i'm in the middle of nowhere and want it to cool faster. like hosing it off, or ice, or what?
it's a fairmont with a 302, all cast iron parts except the headders (steel)

Would a giant fan in front of the car work if i stopped at a gas station, and opened the hood up? i've seen it done at the strip a few times...
if i drive with the heat on full temp, and on Hi, it stays close to 190 on highway.
it stay at 185 when in city, with heat off.
I'm not sure how to check for flow, the thermostat is brand new, but the pump is older...
the gauge is aftermarket, and last year it said i was running at 230 all summer... the oil pressure gauge always said it was at 125psi... that gauge also said i had around 60 psi before i even started the engine...
I am going to change the oil and filter soon as it is coming up on the 3K mile mark. someone once told me the fuel mixture can change it slightly. when i was a mopar nut, i read in a few places that the 426 hemi ran so hot, chrysler had the mixture set really rich, using the fuel to cool the cylinders down...

I've been thinking that for quite a while now... same with the oil pressure gauge...I'm thinking that it is a flaky temp gauge.
the entire system was flushed last year, as i had upgraded from an inline 6 to the 302.You can check the flow by removing the radiator cap on a cold motor. Then start the engine. When the thermostat pops open. You should see a nice heavy flow of coolant in the radiator.. When was the last time you flushed the system??? It might be all that's needed. If the Thermostat is new then I doubt it's the problem.Unless you put it in backwards. I humbly admit to doing that before as I was talking with friends & drinking a few beers while working on my Camaro..
it's not that big of a deal, but it just got me worried for a sec. like i said, i planned on using them as a guideline. and all gauges are aftermarket, as well as their sending units...Can you borrow one of those infrared thermometers? ANd measure the temp?
I am pretty sure that the temp guage will go full hot if it is grounded, and with added resistance it will go cooler and cooler. Maybe I got that backwards.
I believe that the Oil guage more often than not is not really a guage as much as it looks like one, but rather it is connected to a switch. Under 5 psi it registers low, and the oil light comes on, over 5 psi the switch is closed and the guage shows middle / normal range.
i just thought of the difference in city and highway. in city the tach is usually close to 1500, on the highway it's hovering just below 3000. that would be my increase in temp over the other end of the equation.
the radiator is from an 89 crown Vic. but when i switched them, there was no difference in size... i think the 6 came with an 8 rad...
