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.

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.

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
