Engine temps

[Red Reaper]

what is the best range in terms of engine temps that you'd want your 302 to hover around on the warmest days we may see in the Summerchant? 180 or 190?

My all iron carbed 333 stroker runs around 170* water temp and 190* oil temp on all but the most brutal of hot days, or if I'm beating on it. Be Cool alu rad, Ford racing oil cooler, Victor water pump. EFI motors usually can run a bit hotter, carbed likes cooler better.
I would say 185* would be a good target, I wouldn't like mine any hotter than that.

[Red Reaper]

Wow ok unless my fairly new temp gauge is faulty I'm hitting 210 and my car started bogging pretty bad

Are you running electric fans or just the stock fan?

Mine runs steady at 190 all day long, but hits 210 at the track. No bogging, but i bring her in to cool off. Have a new water pump to install.

[Red Reaper]

Stuck in a bit of traffic and it got to 210 and every time I left a red light she would bog and cough backfire a bit then I'd just floor it and it was like she cleared her throught it then continued on not as rough but still noticable

I have a Flexalite 175 electric fan. 210 is way too hot in my opinion; you may need to think about electric fan or a new water pump, if that reading is correct.

[Intmdtr]

Do you know what's in it for a thermostat?

[ZR]

If it's running that poorly at those temps, either rich and partially fouling a plug or going extremely lean, either one can cause the symptoms your describing. Ideal / best performance temp would be 185-200, however for many combinations you'll see temps far north of that on a hot n humid day. If your fine on the hwy and only rises at lights or slow driving, needs more air / upgrade to your fan and or correct tuning.

Ideal is 180-185 on a 302 but it may climb a little high on hot days to around 200. Mod motors run hotter than push rod engine. Mod motors high speed fan doesnt even come on until 210 deg.

[Red Reaper]

Unfortunately everyone I've taken it too never seem to be able to get my car running correctly it's been to the most of the reputable shops and I've been a pretty patientian guy but with over 10 grand spent on parts and labour with the car still runNing this way it's just starting to piss me right off.

I run 180 to 200 on a 500 hp built 306 with 6psi paxton stock fan and water pump. It stays in the garage on hot humid days and never seen track or traffic

If you mean dual Mishimoto fans, dump them for a single Taurus or similar fan along with a quality controller. That will get your temps back in check then you can move onto the running issue.

Taurus fan pulls HARD.

[ZR]

It surely does. Exactly what is required to get the job done.
Does require a high current controller though.
Well worth the effort and cost.
Another option, fan from a '99up GT / Cobra etc

If I told you that I had one running around using a Ford starter relay, would you believe me?

About to replicate it on my own wheels here shortly.

If you have a stock width rad or Modular motor swap, I would agree...

I have the '03-'04 OEM Ford Cobra fan (using a Ron Davis 70 amp relay) + Northern rad in the Project Car. There might be a quarter inch of clearance between the fan motor cover and the water pump pulley bolts.

Rick, what years of Taurus have this great fan?

[Slope]

Early 90's V6.

You'll have to fab up the coolant overflow bottle mounting, but it's a little work for a great Fox fan.

I did one way back when using a commercial / continuous duty solenoid (looks very similar to a starter solenoid), worked like a charm.

Took some flak when mentioned to some about using a starter relay for continuous duty.

Let's think for a minute on what demands that relay is under during it's intended use vs. what we are re-tasking it to do.

"It's not gonna work"...

[ZR]

Typically a starter relay does not stand up all that well but there are some exceptions. Continuous duty one is a good option, can be spendy though.

[Red Reaper]

Ok so let's say any 90 to 95 Taurus fan will work?

Hmm, maybe worth looking into to do on the cheap. Paint it black and tuck it away.

[Red Reaper]

So that's what I would need? ZR would you have any of these fans kicking around?

Might want to contact Twister, bet he'll have or can source one.

[Tailites]

any decent 40 amp relay should run the fan..

Nope, Taurus or Cobra fans spikes huge on start up.

Um, I'd hedge against longevity on this one...

Taurus is approximately 88 amps if using the High side.

I'm willing to bet the '03/'04 Cobra is equal or better.

[Red Reaper]

A little.lost in the convo so the controller I have would not work.and a cobra fan would be better. What relay would I need?

Controller you have is not rated high enough (amps) to handle either Taurus or Cobra fan.

The 2sp controller will control all of the two speed Ford cooling fans, including the 3.8L Taurus fan correctly, the low speed circuit is calibrated to turn the fan on low at 185F, but is adjustable over a wide range of temperatures. The high speed circuit turns the fan on high at 10 degrees higher in temperature while disabling the low speed circuit

Sadly that is all too common. Demand for them is always high. Wish someone else made a unit of that quality.

The better of the two Flex-a-lite controllers will also manage the fans in question. It's not cheap either, but at least it's available.

Close enough to call em equal.

LMFAO have you ever data logged your car and seen when it goes into open/closed loop? Because I have and your statement makes no sense. plain and simple.

And both cars are running great after 4 years. plus get over 400 to tank fuel also air/fuel spot on as well.

open/close loop is not as much of temp verses time. data logging shows that.

I use a FLX-175 with good results - recently had to swap out the motor after about 5 yrs.

[ZR]

No idea why but, have experienced at least a couple or three that refuse to stay cool enough with that fan. Took the Taurus fan to tame em.

[tulowd]

maybe cause I have the oil cooler mounted directly in front of it as well as the big alum Be Cool rad and Victor pump?

Very possible Paul.
Have seen others without the extras that got by just fine. If it was mine and keeping it cool is the priority, would go with Taurus just to be sure.

[bluetoy]

Just a quick thought. are you running just straight antifreeze. That would cause overheating. Just a thought.

[Red Reaper]

Should be 50/50 I should check on that.
