It was unintentional!
I always wanted a Jaguar, in fact I always wanted an E-type, then an XJ6 and then an XJS because they just looked so good. In 2001 I bought a 1986 XJS V12 with 70,000 miles on EBay from a guy in New Jersey.
The EBay listing said that it was 'near mint' - this turned out to be true as the car was located near the Philadelphia Mint.
I flew down to NJ to drive the car home, paid in cash at the airport and was now the owner of a shiney red XJS.
The seats and interior of the car were a little damp, apparently, the previous owner claimed, the windows had been left open when going through the car wash. I usually stay in my car when going through the car wash, they must have a fancy new 'unattended' car wash in NJ.
The previous owner was kind enough to lead me to the freeway to drive home to NH, we waved goodbye and I was on my way, the car shaking a little at 40 mph, shaking more at 50 mph and whole lot of shaking going on at 60 mph.
"I'm sorry officer I had to do 80 because the car shakes at 65".
I decided to stop for gas as the needle was jumping between empty and full, apparently it was near empty when I filled up, it was just $1.18 a gallon then. The needle was steady when the tank was full.
Back on the road I decided to start playing with some of the buttons and dials in the car, I turned on the radio, the aerial raised itself half way and stopped, providing clear static on each radio station. Then the radio/cassette swallowed and jammed my cassette tape, it would be a peaceful drive home.
The A/C was apparently set to hot, then hotter and finally hottest, so that was turned off.
Skies were darkening so I checked the wipers, amazing that they couldn't wipe the dust off a clean windshield with the aid of an 80 mph wind, luckily they worked a little better once it started to rain.
I felt a little water leak coming from the driver side door, then a little leak from the passenger side door, then a larger leak from all four corners of the windshield. The carpets were getting
wet soaked, I was getting wet. Only 6 more hours till I get home.
My wife called me on my cell phone "how's the car?" she asked, "it's unbelievable" I said. I was looking forward to visiting NJ again sometime in the future.
Later that day, as I finally ended my adventure and drove into my driveway, the radiator gushed with excitement. Coolant was everywhere, just no longer in the radiator.
I thought "Jags really are a great third car".
... and so v12s was started.
Think of a v12 engine as you would think of a freight train.
If you were driving a Freight Train you wouldn't put the brakes on when you get to the station, you would put the brakes on a long way before you get to the station.
This concept applies to the v12 engine. You wouldn't start your cooling fans when you reach operating temperature, you would start your cooling fans before you reach operating temperature.
There's a lot of metal and a lot of fluids that need to be cooled and it can't happen instantly.
Do modern cars have electric fans instead of mechanical fans?
Yes they do, and yes you do.
Anyone that tells you that you don't is only saying that because they don't have a fan shroud and just want to sell you an electric fan.
Our electric fan systems are complete with a handcrafted shroud. A fan shroud will allow your electric fans to draw air across the whole surface area of your radiator. If you simply attach one or a couple of electric fans to your radiator core without a shroud then you will reduce your ability to cool your engine by at least 30% - 40% or more.
Using those zip ties is a butcher's job of attaching an electric fan. Do any car manufacturers have fans on their cars without shrouds these day? No of course not! Does any car manufacturer use zip ties to attach an electric fan to a radiator? Duh! No they don't.
Well, we're not going to pay it for you, so ...
Our products are shipped from tax-free New Hampshire. All items entering a foreign country are subject to customs inspection and the assessment of duties and taxes in accordance with that country's national laws.
Customs duties and taxes are generally assessed if the merchandise is dutiable and the value of the item is above a set amount determined by that country's laws.
These charges may be due at the time of delivery and they are separate from shipping charges.
We will not ship items as 'gifts' or 'scrap'.
A lot of them are simply liars. Did they fool you?
Some fan sellers appear to defy Ohm's Law when describing their fans, apparently they haven't heard of Ohm's Law.
As an example, a 14 inch fan with a 90 watt motor draws approximately 7.5 amps, not 10.2 amps, at 12 volts DC. The same 14 inch fan with 90 watt motor draws approximately 6.7 amps, not 10.2 amps, at 13.5 volts DC. Check out Ohm's Law to determine if the fan seller's claim's match the fan being sold.
Some fan sellers promote CFM as being the only important consideration, but it's not.
As an example, a 16 inch fan with a 250 watt motor (apparently only 10 amps at 13 volts?) - is claimed to generate over 3600 CFM at zero static air pressure- that's 3,600 Cubic Feet of Air Per Minute, or presented another way - enough power to move all the air out of a room that measures more than 22 feet by 20 feet with an 8 foot ceiling in just 1 minute - what load of bull!
Here's another good joke - a 13 inch fan with an 8 amp fan motor (about 100 watt motor) claimed to pull 2900 CFM, more bull, divide the CFM by 2.
I would welcome fan manufacturers enlightening me with their scientific proof but they ignore requests for independent lab data showing their CFM figures, in fact one fan manufacturer specifically told his sales rep not to talk to me - they can't handle having their BS claims challenged.
A word about quality: there's plenty of cheap $5 fans available that look the part but are nothing more than mere inferior copies of brand name fans. Did you know that the plastics used in cheaper fans are inferior polyproylene mixes? This makes these inferior fans less impact resistant and less capable of coping with high temperatures - ie. brittle. Quality cooling fans are made with plastic composed of glass-filled nylon. You get what you pay for, right? Some people don't care about what they sell to you, we do, we give a lifetime free replacement warranty, every fan supplier should give a lifetime free replacement warranty - don't buy a fan without a lifetime free replacement warranty.
I've built over 2,000 electric cooling fan assemblies for v12-engined cars and others, so I have some experience in choosing the right electric fan and weeding out the fact from fiction. My fans are 70% more powerful than the common fans available elsewhere. So, here's what I look for when choosing fans.
Firstly, some things to think about before buying an electric cooling fan:
- does your car have a/c condensor mounted in front of the radiator?
- does your car have a seperate oil cooler mounted in front of your radiator and/or a/c condensor?
A 10 inch fan with an 80 watt is fine for most applications where only a 10 inch fan could fit - this excludes all V8, V10, V12 and bigger engines.
A 14 inch fan with a 90 watt motor (most 14 inch fans on ebay) that spins very fast may be OK if you have a thin radiator and no A/C condensor or other coolers in front of it - it's not OK for a V12.
If you have A/C then I would choose a fan that has a 120 - 160 watt fan motor.
If you have an A/C condensor and another oil cooler in front it then you would want to use a fan that has a 160 - 225 watt fan motor.
When you bought a shop vac what did you buy? The weakest or the most powerful?
Of course current draw is important, but that doesn't mean sacrificing engine cooling. If your classic doesn't have enough amps to get the job done properly then buy a more powerful alternator and battery. Destroyed engines due to a lack of cooling, especially in classic cars, are an expensive and foolish error.
And what about curved blade fans versus straight blade fans? The patent for curved blade fans only claims that they are quieter than straight blade fans, there are no claims of more airflow (all things being equal).
In conclusion, this Fan 101 isn't meant to cover everything but it is meant to highlight some fact from fiction.
