Be sure and get your gas early in the morning and keep above 1/2 full , this will keep more liquid in your tank and less evaporation,,,hence better fuel economy.

ive posted the FSM link here 100 times.

you can google and youtube 1000s doing it.

its a standard service part (short lived)

97 GC, here , ill spoon feed yah.

go here


and then pick cooling system.

note careful there is more than one engine uses on most cars made

so getting help not knowing that, is well, impossible.

the 4.0L (wild guess) I had 3 jeeps that engine. and 1/2 million miles.

  1. Drain coolant , same chapter.

  2. see top FAT RAD hose? (of 2 hoses big , its the top one)

  3. follow it to the THERMOstat housing ,

  4. unbolt it, BAM the thermosat fell out.

  5. watch out 4.0L are very hard to BURP

  6. put in a new STAT wax side to water jackets, and bleed /pin hole up hill.

  7. I will not tell you how to clean gasket surfaces, google it.

  8. my stat says, 180F or more on the side, NEVER LESS,ever.

  9. I reverse above. but i fill the engine with AF until it leaks out

  10. and burb it.

  11. test for leaks 3 times. and every morning for 3 days, if savvy

The 4.0L is very hard to burb so dont forget to make darn sure the water jacks are full of AF> 50% and then all hoses above that.

THE FSM shows even raising the front bumper high on the

early 4.0L I-6s cars... it was so hard. my 99 was more easy.

but do make sure you run the cold engine with rad cap removed

then add AF 50% until its really full.

as the engine heats, the AF will overflow the rad neck

dont panic, just cut the engine and put the cap on,

the coolant is not too hot yet.

now driver around the block, 1 lap

come one, and let it cool, (side tank , clear, is 1/2 full)

now when 100% cold, take off the rad cap

makes add AF again. on the old 4L ive had to do this 3 times.

then make sure hoses in the side expansion tank are not

missing ,fell off or , cracked, or there will be problems.

i never trust any side tank, until ive tested it fully.

once it works right, it will keep the rad full. but keep that in mind.

ive seen many drop the suck tube and render that bottle useless.

my new jeep that made this impossible. with cast in tubes.

genius design that. 3.8L.

When I fill the car up, at some point, fuel spills out before the fuel flow stops automatically as it should.

Hi, probably a clog or mis-positioned vent tube in your filler neck. FYI--- filling your tank on the lowest pump speed will give you more gasoline upon fill up. The higher the fuel delivery rate, the more fuel is vaporized in fumes coming out of the gas pump. Pumps are equipped with vapor recovery, so around 3% of what you are paying for is actually recovered and returned to the station's tanks via vapor recovery. Lower delivery speed reduces vapor, so you actually get more of what you are already paying for. Also, fueling when the air temp outside is lowest (early morning and late evening) produces less fuel expansion and less vapors. Fuel expands with heat, therefore you lose 2% per 10 degrees of heat due to liquid expansion. Lower speed will also help with your overflow issue.

My car doesnt want to start up right away in the morning. Almost like its really cold out and it takes it a min. The rest of the day its fine runs great. Any ideas?

Reason 1 - Gasoline, like any other liquid, evaporates less when it is cold.You have seen this -- if you pour water onto a hot sidewalk it will evaporate a lot faster than it will from a cooler place like a shady sidewalk. When it gets really cold, gasoline evaporates slowly so it is harder to burn it (the gasoline must be vaporized to burn). Sometimes you will see people spray ether into their engines in cold weather to help them start -- ether evaporates better than gasoline in cold weather.

Reason 2 - Oil gets a lot thicker in cold weather. You probably know that cold pancake syrup or honey from the refrigator is a lot thicker than hot syrup or honey. Oil does the same thing. So when you try to start a cold engine, the engine has to push around the cold, gooey oil and that makes it harder for the engine to spin. In really cold places people must use synthetic motor oils because these oils stay liquid in cold temperatures.

Re ason 3 - Batteries have problems in cold weather, too. A battery is a can full of chemicals that produce electrons The chemical reactions inside of batteries take place more slowly when the battery is cold, so the battery produces fewer electrons. The starter motor therefore has less energy to work with when it tries to start the engine, and this causes the engine to crank slowly.

All three of these problems can make it impossible to start an engine in really cold weather. People either keep their cars in heated garages or use "block heaters" to get around these problems. A block heater is a little electric heater that you plug into the wall to keep the engine warm.
i hope it was convince answers

check engine light indicator is on...after total

Obviously you have something above the tank that's leaking. That will result in a code the same as a bad or loose gas cap. At this point, the only way you can find the source is to take a good look at everything, even if it means dropping the tank to do that. (better than wasting fuel or having a fire start under there).
