P0303 and Coolant
 
Jeep in question is my 2000 XJ. 4.0, Aw4. 95,000 miles

On the way back from Seattle today, I drove down a washboard road for about
7 miles, got gas and went to get back on the highway. Less than one mile
after fueling, I get a CEL. Pull over, gas cap is tight, everything looks
OK. Continue around 100 miles home, CEL solid the entire way. Fuel near
home, 15.5MPG! I had previously gotten 21.1, 18.9, 20.1.

Stop at CSK, pull the codes, and I get P0303. Cylinder number 3 misfire.
Plugs are new copper champ's, Throttle body was recently removed and
cleaned. Any ideas where to start looking?

Also, I'm planning on changing the coolant soon. I have heard I can get the
prestone heater hose tee, and flush it with a garden hose. Then drain the
radiator thru the lower hose, fill the radiator with distilled water. Drain
again, and refill with 100% coolant. Will this give me the right mixture?

Thanks,

Carl

Try cleaning the plug, you may have a bit of carbon in the nose cone causing
an short. It that doesn't 'cure' it replace that plug.

Cooling system: I recall your system holds 12 quarts but check your
manual.. DC recommends you upgrade to the new spec G-05 coolant although
you may continue with the old spec. (see below)

Flushing: If there is a layer of slime in the expansion tank or the cooling
system has been neglected It might be advisable to chemically flush or clean
the cooling system. The flush-n-fill kits make this easy and thorough.

I did several flush/drain cycles to be sure the nasty old coolant was gone
and then let the hose run several minutes after I was sure it was completely
clear.

A flushing of the heater core with distilled water would be a good idea, you
can clamp the hose to force the distilled water back-down-and out.

Add your 6 quarts of Zerex Original Green or Zerex G-05 concentrate to the
system and another quart (7th) to the expansion tank and then top off with
additional distilled water.

That should give you -57/+270 protection.

You can use the Tee to 'burp' the system that otherwise would work out over
the next several days of driving. In a few days check the expansion tank
and re-top as necessary.

Re: P0303 and Coolant
 
The coolant drain in the block is the way to go, if you can get at it.
Sometimes you can't, or it just isn't reasonable. In that case some kind of
flushing is indicated. How much flushing you do, depends on what kind of
junk comes out. Pouring in distilled water before the last drain is a good
idea, because you really don't want to leave much tap water in there. I had
good luck pouring a quart or two of distilled water through the heater core,
with the hoses disconnected from the engine. In most vehicles you can
bypass the annoying "burp" phase, by making sure that the engine is full, up
to the cylinder head. You can use a heater hose fitting or a temperature
sender as a bleeder if you want to do this. If you plan to use the tee,
make sure it is in the hose that goes to the head, not the one that connects
to the water pump, and that it is uphill from the engine.

It's a lot simpler than it sounds, unless you do something wrong.

Re: P0303 and Coolant
 
So I'll need two gallons of coolant? Is one radiator flush better than
another? I have always used 'Water Wetter' with good results. Will 'Water
Wetter' work with the Zerex G-05?

Thanks,

Carl

Re: P0303 and Coolant
 
DC states a warning in the manual in bold letters that you shouldn't use
wetting solutions..

I used Zerex flush, if your cooling system is really dirty the Zerex cleaner
is stronger.

Two gallons of coolant should leave you a bit to spare.

Re: P0303 and Coolant
 
How exactly do you know that you "have always used 'Water Wetter' with good
results"? Because the car still ran afterwards? I don't think you need it.
Water and ethylene glycol are pretty darn wet already! Billy Ray says so
too, and he's some kind of chemist.

If the coolant presently in the system is pretty clean, and you can get the
drain plug out of the block, then I don't think you need to flush with
anything but water, if at all. Don't forget to rinse the overflow bottle
and the heater core. These are spots often missed.

Re: P0303 and Coolant
 
You can drain and refill the coolant all you want -- probably a good thing
by the way -- but this will not fix the error code.

If I got the code you got, I'd be looking at stuff like spark plug wires or
the coil (if the motor has a dedicated coil for each plug). I certainly
would not spend time and money on completely unrelated systems, especially
when those systems have their own series of codes to tell me when they are
not feeling well.

Re: P0303 and Coolant
 
You can drain and refill the coolant all you want -- probably a good thing
by the way -- but this will not fix the error code.

If I got the code you got, I'd be looking at stuff like spark plug wires or
the coil (if the motor has a dedicated coil for each plug). I certainly
would not spend time and money on completely unrelated systems, especially
when those systems have their own series of codes to tell me when they are
not feeling well.

Heh, I read this as two separate issues. ;^)

You are right that he needs to address the spark issue too.

Re: P0303 and Coolant
 
It's probable since you just replaced the plugs, that you got one that
is defective. I have seen this in the past. Change #3 again, check
wiring and coil connections (if present), clear the CEL and retest.

If you must flush, use very low pressure compressed air to clear tap
water out of the system. I've also pulled heater core hoses and cleared
them separately.

Also, this is a good time to drop hints that you need a good code
scanner, since Santa is generous this year.

Re: P0303 and Coolant
 
Yes. What would you deduce from a P0303 code?

HINT
The code means the #3 plug is not firing properly, which by definition is a
spark issue.

Re: P0303 and Coolant
 
Thanks for the responses, guys. I cleared the code last night and drove
about 20 miles, it hasn't since returned. I'll change the plug today anyway.
There are no plug wires on a 2k. Instead, there is a coil rail with three
coil packs. The P0303 and the coolant are completely unrelated issues, I
just posted in one post to keep the clutter down.

My research has shown that the P0303 problem is known to be a heat soak
issue with injector #3. Apparently, sometimes the heat from the exhaust
manifold will creep up to injector #3 on a hot shutdown, causing a misfire.
The fix is an insulating wrap around injector #3.

The coolant in the radiator right now is brown. I assume someone drained the
radiator and re-filled it with standard coolant. That's why I want to flush
the system. I read that there is a 7-hour flush. Apparently I just add it to
the radiator (after draining a small amount, of course), and it cleans the
system during a seven-hour drive. I'll be driving back over to Seattle next
weekend (a five hour drive) and I plan to change the coolant while I'm
there. Am I barking up the right tree here?

I have seen positive results with using water wetter in an all ready good
cooling system. I would not expect to see results using a it in a clogged,
contaminated, or otherwise maulfuntioning system. Per reccomendation here, I
will not add it to the XJ. Just curious why they say not to use it?

Re: P0303 and Coolant
 
Brown coolant is undoubtedly bad, but it doesn't necessarily translate to
scale and sludge in the coolant chambers of the block or blocked radiator
tubes. I would flush the system with water, and only resort to a chemical
flush if big pieces came out. Otherwise, you can assume that most of it is
already in suspension. Another tell-tale is the bottom of the overflow
reservoir. Nasty pieces will tend to accumulate there because it doesn't
really have circulation. I am against flushing with chemicals unless you
have reason to believe that they are necessary, and then you have to take
extra care to rinse them all out afterwards.

When you say "positive results with using water wetter in an all ready good
cooling system" what do you mean exactly? Lower reading on the temperature
gauge? I don't get how you can tell, that this stuff is doing what they say
it does.
