SVX Engine cooling "Again & Again"

Trevor,

I have my fans hardwired on to full speed. Mine still overheated.

Your entire last post is a prime example of the holier-than-thou nature which leads most of us to ignore what you say or at the very least discount it. Simply because we find it irritating to read your roundabout posting style does not translate to having an inability to read or understand what we have read.

Have you not noticed that it was quite possible for everyone else to convey these "complex issues" in plain English? Imagine that; a technical discussion devoid of unnecessary filler!

I can understand why Trevor asked the question regards the fans but in a vehicle so well acoustically silenced as the SVX is, I can't imaging it would be possible from the driver seat to say with certainty if one or two fans are working all the time.

In my car I can hear the fan/fans working or not working, but there is no appreciable sound difference for two fans over one fan, not to my ears anyway. Maybe you guys in warmer countries drive with your windows open a lot?

On a related but tangential topic it has to be acknowledged that the operation of the fans in a high heat situation is designed to speed up the dumping of excess heat, or assist with cooling if you like. As such their operation is an inherent and important part of the installed system.

Just the same if the electric fans are having to work full time [overtime, if you like ] in a non modified EG33 to control a heat problem, then you are in a situation where you are merely using the fans to control or ameliorate the Effect which is overheating, rather than discover and adjust the Cause of this overheating.

In climates where high ambient temperatures mitigate against the effect of the two fans in cooling a hard worked EG33 such as Matt's case above, then we are back to the situation that another part of the installed cooling system must be falling down on the job. That could be a flow or cooling imbalance between the blocks or a restriction to flow that only happens under high pump speeds or a radiator that does not flow enough coolant, a number of things.

The fans are not the problem here, although a full-time on switch would be a sensible addition for hard worked cars or cars operating in extreme heat areas. We are still trying to identify and define possible flow restrictions and agree on a solution that will fix the problem. Nobody currently doing modifications to the SVX cooling system has the benefit of a research laboratory to measure Cause and Effect modification by modification.

Joe, you complicate the issue and bury my post.

The thread is full of such surplus comment and yet I am the one currently accused of same.

I have asked a simple and exact question. It is obvious why I have asked the question. That is because it is very possible that the fans were not running. Now we have endless text pointing out the obvious, i.e. why this might not have been detected.

You then go on to try and relate my post to Tony's problem and still further confuse the issue. What is the point?

Joe SVX fans both runat the same time at at the same speed. They are 3 speed. The top speed will not come on if the AC is off even if the engine is boiling.

Thanks Tony.

That's why I suggested an "over-ride" switch that could force the top speed function for high heat situations.

Trevor, with respect there was no intention to confuse the issue or bury your post. Nor am I one who usually criticises your posting style. [although you will never be accused of the same ]

My point is valid and important. People are experiencing overheating even with fans working on full. It's vital and important to ensure they are working as intended but the cure for the overheating problems lies elsewhere in the system.

It is a fact that it is more than irritating that here, many posts do not clearly define the authors intended message. My statements are direct and exact and are not round about. You are stating that any person writing in an adult fashion, necessarily illustrates a holier-than-thou attitude, ---- balls.

Your middle attempted sentence represents childish English and bad grammar. Try --- " The fact that", in lieu of "Simply because". If you are unaware of the difference, that is your problem. I do not intend dumb down to your level.

Choosing one sentence out of someone's post and using it to disregard everything else they've said without addressing the points present in that post is exactly why you come off the way you do, Trevor.

Could you not see how insulting your post to shotgunslade was? The way you wrote it was not the way an adult should speak to other intelligent adults. It is obvious by reviewing this thread that he does have the ability to read and comprehend English. Comprehension is not the issue; rather, it is rather the way you refuse to directly address the topic. You fill your posts with needless commentary rather than sticking to the technical problems at hand like everyone else has done.

Since I do not own an SVX and will not again own an SVX, I suppose I have no right to impose in this thread any further. With that parting message I will return to passively watching everyone's progress and hope that those here with more valid positions in the community may echo or more better express my observations.

Trevor:

There is no need to address any more posts to me. I do not wish any more of your "help." So far, you have contribued nothing tangible to this discussion, whetner experience with the issue, or expeiments with it. We would all be better off if you developed an allergy to your keyboard. Rest assured that any further posts from you will be unread at this end.

Thank you Matt,

A similar courteous, prompt, explicit, response from shotgunslade, in reply to my original post offering him a assistance, would have been equally well received.

Sincerely, Trevor.

As previously I again exactly address the points involved. I have never refused to directly address a topic. No one else has stuck to the technical problems at hand. It is a recorded fact that I have been trying to correct this exact problem.

Shotgunslade made the introductory statement --- “I have to say that half the time, I don't understand what you are saying.”
Then continued with --- “In any event, I have no idea what point of view you are bringing to this discussion. Rather than try to decipher your posts, I mostly ignore them.” These were virulent words.

As a result of these statements, I responded accordingly by clarifying my wording. The fact that I had not received a reply to a simple statement made this necessary and logical, as it had been made very clear in very terse language, that I was not being understood.

My reply was factual. I am not responsible for clear text being interpreted as sarcasm.

You are able to address me by my Christian name, but constitute no more than a very poor signal within cyberspace.

When this thread runs its course, I will list each fact which I have contributed. I have a very clear understanding developing, in regard to a somewhat unsavoury aspect perhaps not apparent at the moment.

[svxistentialist]

Diverse, diffuse, chaotic and difficult to decipher as this thread may be, it is still too valuable to the community to allow it to slide into petty interpersonal bickering.

Please observe the rules and keep on the technical topic, and away from personal rancour.

Thanks.

Joe

I have a stock cooling setup (radiator, lines, crossover, etc.). The only change I have is that I HAVE PUT A SWITCH BETWEEN THE IGNITION AND FANS. When the switch is on, both fans run on the highest speed. I spliced the wires into all of the fan leads.

I can say with certainty that with my setup, which at the time included a blown head-gasket, the fans did not make a difference in any way. Stopped or driving, fans on, fans off, and any combination of the above.

Cam, I'd like to make a comment on what you say here, and I hope I understand what you mean.

If you had a head gasket gone and an overheating problem then perhaps it is no surprise that the stock fans were not able to keep temperatures down even at full belt.

Fans working on an otherwise standard engine without a cooling problem will have a positive effect if they are set up properly. By set up properly I mean that attention should be given to ensure that all the air drawn through the rad is coming from the front grille area, i.e. from outside the car, not from the engine bay, which is warm air.

I'm saying this because practically every SVX you look at no longer has the piece of foam in place across between the rad and the aircon matrix.

At the Japanese Car Show I was discussing cooling [and intercooling!] with some racing teams last year and they pay meticulous attention that all the air drawn through the rad is cold air from outside, sealing up any side gaps or top gaps such as exist with the SVX twin rad set-up. In the case of the SVX at speed cool air forced onto the rad can actually get through the aircon rad, then bypass into the engine compartment if that is the path of least resistance. This has to have a negative effect on cooling capability and should be attended to by racers.
