FE cooling questions

[HTM101]

The Spal 30102120 is a great fan that I used for a number of years. For our 90+ degree days and those times I've been stuck in slow traffic, I decided to add some cfm, and installed this Spal fan #30102113.

Last year I was in a traffic jam that was miles long. 85 degrees ambient temp and I moved less than 2 miles in 25 minutes. The coolant temp never exceeded 90 degrees C.

Although it moves a tornado of air, there are several caveats in the manufacturer's description to consider.

Now, I do have my pusher fans wired in on a supplemental circuit. And they do indeed make a difference when I really, really need it, which I never do unless I was trapped in a really bad, hot, backup, which I never have been. More likely, it would save my miserable butt from a boilover resulting from a failed SPAL motor, or a failed relay, or a blown circuit breaker on my primary puller fan side. I think my pusher fans would get me through most "moderately hot" situations. Here's the thread on how I wired it: Cool Modification - For Pusher Fans Only, Though

Going to reverse-flush the system in the next couple of hours. I'll see if I can get a pic of how I rigged it for flushing .

Dan: I wish it was the "Polar" type, as in "north polar", and blow cold air instead of the 95deg soggy gas that we call Air down here.
The Taurus fan has a integral shroud, which had to be modified to fit, and it works well (approx 4000 cfm on hi.)
I don't have specs on the radiator, other than it's the original installed by Kirkham.

A good friend of mine, southern club member had a severely overheating engine that had just about everything thrown at it, water pump, thermostat, radiator.

I asked to make a video with an IR gun, and listening to the engine boiling as it was shut down, I said the water leaving the passenger head is the cause.

I asked him to pull the manifold, and there was a rag stuck in the head.

Back in 2008, the engine was assembled 8 years ago, (2000) but the fault only started about a year ago, (2007).

Flushing showed nothing abnormal. Will run it tomorrow and check head temps.

Gary: checked head gasket orientation, Both sides have a corner of the gasket sticking out on the front lower corner, which I believe is correct.
I hope I can find a "Rag" !!

You that have incorporated the siphon style coolant tank add-on, what tank did you use and where did you locate it? Does the tank have to sit at the same height as the FE tank or do you have issues of it siphoning too much out?

Pictures of your tanks and install would be very helpful

Overheats while moving, or stationary?

It appears that all is well now, but time will tell.
Turns out that I was looking right at the problem all along without realizing it! Even with the water temp below boiling, running aprox 180 f, water/steam was being discharged thru the o'flow hose. Got out my long forgotten pressure test kit and found the cap would hold no pressure, also tested block/radiator, it held pressure,no internal leaks.
New cap (13#) and thermostat installed, test drive was good with the temp staying just under 180 Deg, with no fan running.
Still need to find a recovery can that will fit in the limited space available fwd of the eng.

Thanks for all your help' Ted

Glad you found the problem.
