Subject: Voltage Spikes?
Hi,
Here's a quick question. I think I know the answer, but just want to be sure. I have #4945 which has an Automatic Transmission. I just had the Computer Governor replaced and I know voltage spikes can kill them, so here's my question. I have a quick disconnect on my battery so that it doesn't die when I'm not driving my DeLorean. Reconnecting the battery(turning the knob) isn't considered a voltage spike, is it? Just want to make sure. Thanks for your help.

Subject: Re: antifreeze question
The water is what helps cool the engine , the antifreeze is for well
so the water doesn't freeze and to lube and protect the internal
parts from corroding due to there is water in the system....and also
(I believe) to keep the boiling point of the water high (so it won't
boil). If you put straight antifreeze into the engine....it won't
cool it as efficiently (especially in this heat!) and may even come
close to over heating. Follow the mixture. I believe Prestone makes
ready mixed antifreeze so you don't have to go through the trouble. I
would suggest that you fix that leak because it will turn into a
major problem unexpectedly. Even though it is very small….just from
the heat of the coolant expanding and contracting the parts it will
get worse.

If I understand correctly, the scenario you describe (using the A/C to make
the fans run) would indicate that the otterstat is stuck in the "off"
position, unable to complete the circuit and allow the fans to run...right?
But couldn't the opposite occur, where the otterstat is stuck in the "on"
position and the fans run all the time?
My fans run continuously, but when I pull either of the otterstat wires they
stop. When I plug the wire back in, the fans start back up. I presumed
this meant my otterstat was stuck "on." Is that not necessarily the case?
Can the otterstat only fail one way?

David, Are you complaining it's to cold. The otterstat that it sell now turn
on at 199 Degrees, that's at the otterstat temp. The heat sending unit for
the gauge is at the engine block. That could make up the difference. Sit back
and enjoy. The radiator could be not cooling down as fast and make sure that
both fans suck air not blow.

Subject: Re: when do fans come on?
The temp gauge in the Delorean is not that accurate. If you suspect a
problem then you should use either a Templestick, a thermometer, an
infrared thermometer or some other accurate method of measureing
temperature. If your car never warms up it could be a thermostat that
is stuck open or maybe it isn't even there. It is possible that your
otterstadt switch comes on too early, different venders sell
differently calibrated otterstadt switches. It is not good to run a
motor too cold. Your fuel economy will be low and emissions high. Your
engine oil will become contaminated because the moisture is never
boiled out and it will corrode the internals of your engine. You will
not get any heat out of the heater in the winter also.

For anyone who drives their car for long periods of time, or anyone who just wants to up the performance and handling, let me be one in a long line to tell you, the Grady shocks are incredible!! What they do to the car can't even come close to being put in words. Bringing my car back from DMC Joe's I first saw the difference, but the real test was this weekend when myself and the ETDOC went on the Blue Ridge Parkway. No bouncing, no hard hits on the rear, these things are great! For anyone who is debating these, let me say go for it. You definately won't regret it!

Antifreeze should be mixed to the manufacturer's recommendations
(usually 50/50 for mazimum cold weather protection).
Straight antifreeze does not transfer heat as well as a mixture
of antifreeze and water. Do not use tap water. You should
used distilled (not spring) water available at any grocery
store. An easy way to measure your mixture is to fill half
of an empty gallon milk jug with distilled water, then
fill the jug with antifreeze - Presto(ne)! a 50/50 mix.
You now have two half-filled jugs to work with and a gallon
of mixed coolant.

Subject: Re: antifreeze question
You should never run your cooling system with anything more than a
50/50 mixture of anti-freeze and soft water. Any other mixture will
give you a lower boiling point and a higher freezing point. If your
car has less than a 50/50 mixture it is OK to put some anti-freeze in
but normally you should just cut it in half and top off. If you have a
drip you have a leak that must be attended to. It might be as simple
as tightening a hose clamp or it could be a warning that one of the
plastic end tanks is about to blow off! You cannot afford to ignore
ANY leak even minor ones. Remember that the system is pressureized up
to 15 psi and while that may not sound like much you would be
impressed if a hose broke off and the coolant flashed into steam! Last
summer on the Rhode Island Rally one of the cars blew off a radiater
tank and it looked for a second like the car was on fire, it was
enveloped in a cloud of steam and there was nothing we could do to
help him. He had to wait till Rob Grady got home to send him a new
radiater. It is much better to fix your car in your garage than on the
road!

Subject: Cold start valve question
Just took my car out for another 200 mile trip
today...I've now deemed it as "I can trust it" car...
it runs better than my bronco, and it has a rebuilt
engine!
One thing I have done is disconnect the blue cold
start valve to prevent the hot start problem (I hope
the accumulator doesnt go next from the nighmares I
have heard about getting it installed)...
Anyhow, will it cause any damage leaving it unplugged?
Will the car start when it's cold without it hooked
up? It's easy enough to hook and unhook, thats not a
problem, I just want to make sure I will not cause any
damage by doing it.... my D is no longer a "start once
a month, and maybe drive it car", it's now a "any nice
weekend she goes out on the town with me" car - and I
do not want to risk damaging anything...
On a second note while I am thinking of it... the
driver's side floor in my car feels kind of soggy...
is this normal?
I've been extra careful to not put weight on it...I
wasn't sure if it's something that's normal or if I
should have a look at it.
Thanks!

I'm glad you've decided to keep your car. I am even
more excited that you are going to drive it. IMHO.
the joy of DeLorean ownership comes from driving it on
a regular basis. While I only drive mine 6 months out
of the year (it is not a winter mountain car) put
15-20K on it each year.
The good news is that you'll meet new friends, get
envious stares, get "thumbs up" from lots of folks and
have a car that is actually fun to drive. BUT, there
is some bad news. A 20 year old car with only 4000
miles has not been driven enough to display all of
it's individual quirks. They will appear!! Some of
them may well be very frustrating and at least a
couple will cost a few $$$$. HOWEVER, as you have
already discovered, this forum is a tremendous help.
Good luck!

You asked:
"Anyhow, will it cause any damage leaving it unplugged? Will the car start when it's cold without it hooked up?"
The cold start valve only fires when the air temperature is below 95 F therefore the lower the temperature below 95 F the more difficult it will be to get the engine to fire. Other than that there are no ill effects to having the cold start plug disconnected.
To return the cold start valve to its normal operation simple replace the Time-Temperature Switch, this procedure is easily accomplished in just a couple of minutes. The Time-Temperature Switch is part number 102462 and is priced at $38.40 from your favorite DeLorean parts supplier.

He races a later model PRV from an Eagle Premier (like mine) but with

Subject: Re: New Shocks a MUST!!!
As a supporter and admirer of Rob Grady, I am always
pleased to hear good things about his products.
However, I, too, recently put new shocks on my car and
opted for the shocks sold by the midstates DeLorean
club. Price was the primary reason and the fact that
I know Marty Maier and his car made me feel the shocks
would be a good investment.
I recetnly put 2300 miles on my car in less than a
week and I am VERY pleased with the change in the
ride. On the one hand, it is very sublte. The car
still handles like a sports (sporty?) car, but the
ride is much smoother. Despite its smoother (softer?)
ride, it does not wallow.
I can't compare these to any other aftermarket shocks
being offered by the typical vendors and have nothing
bad to say about any of them. However, if you need
shocks and like to save some money, I would strongly
suggest you check these out.

Why did you do this? Leaving the cold start valve plugged in
normally will not cause a hot start problem, and will make cold
starting very hard if not impossible. Just leave everything plugged
in as normal, and if you encounter yourself unable to start it after
driving it, THEN go back and swap plugs with the CPR just to get it
started.

Probably condensation from your AC. My water drain somehow got
clogged up a few days after finally getting my car back on the road,
and I often find my foot getting soaked with water after a hard right
turn. I'm still trying to figure out a better way then a vaccume
cleaner to pull debris out of the drain tube (behind the right front
tire).
I am also glad that you decided to keep your car and drive it more
often. Your post the other day hit me hard, THATS AWSOME!
Good luck with any/everything you do.

Subject: Re: Cold start valve question
Leaving the Cold Start Valve unplugged won't do much of anything, let
alone prevent a hot start problem. The purpose of the CSV is exactly
as it implys. The valve is used only when attempting to start a cold
engine. Quick run thru: When metal is cold, it contracts. Thus when
an engine is cold, it contracts, and thus has more friction. The CSV
is basicly the equivalent of a choke for a carburetor. It shots extra
fuel into the system to create a richer mixture to counteract the
additional friction. As you have already noticed, the valve is
electrical. So as soon as it recieves an electrical current, the
valve will fully open.
What a "hot start" problem is:
The offical name of the fuel injection system is a BOSCH K-Jetronic.
It is known as a mechanical, or Continuous Injection System. An
Electronic Injection System works on the same principal as the CSV.
But rather than wide open, the electrical pulse cycles to control the
fuel flow/amount. The CIS system doesn't need any electronic
components to operate. The injectors are opend via pressure. The
higher the pressure, the wider the valve opens to allow more fuel
thru. Since high pressure is whats needed to open the valves, the
pressure has to be maintained. A check valve, and a fuel accumulator
are both used to keep the pressure while the system is off. If the
pressure is not kept, then the system needs time to "refill" itself.
In otherwords the fuel pump has to rebuild enough pressure in the
system to force the fuel injectors open to feed the engine. That is
what happens when you have a hot start problem.
How the CSV starts a hot engine w/a "hot start" problem:
When you have a hot start problem, the engine is being starved. Since
the CSV is electical, it can open up w/o a specific pressure. That
means that what ever fuel is in the system at the time, can be dumped
into the engine. So in other words, the CSV will feed the engine
untill the regular injectors are ready. BUT, within a few seconds,
the CSV can also flood the engine too. The CSV is only designed to
operate for a few seconds when the engine is first started. And only
when the engine is cold at that. It may be a small item, but that
little valve can dump ALOT of fuel into the engine. And we do mean
dump in the literal sense of the word.
Bottom line: If the CSV is left unplugged, you won't notice a thing
when running you engine, or starting it warm. If you try to start the
engine cold with the CSV unplugged, you will have difficulty. But
that will be the only symptom you have.
I didn't mean to go this in-depth about the fuel injection system
just to explain 1 little item, but it was the only way it could make
sense.
