There is no senor on the expansion tank. Check coolant level in the radiator. Or the sensor may be in the top off the thermostsat housing. Check the senor has power connected to it. If all correct remove senor and fill with coolant, it my have gatherd an air lock under the senor.

SOURCE: its throwing coolant from rad

Could be a resticted radiator, or a thermostat that is stuck closed. A BAD HEAD OR HEAD GASKET WILL NOT HOWEVER, ALWAYS MIX OIL AND COOLANT. The best thing to do is purchase a block tester. It's a cheap(around thirty dollars)way to rule out a breached head gasket. Most parts stores have these. Follow the enclosed directions. If you can rule these combustion breeches out, then replace the thermostat, and if that fails, my next guess would be a restricted radiator. I am assuming that your coolant fan is operating properly.

Why is the coolant overflowing when the temp guage gets half way?

well the tank must never be full, when engine is cold
was it? (read operators guide to see methods)
water expands hot, and the tank captures this expansion
that is normal.
what does "until its all gone", mean, what is IT?
there are lots of tests.
the first one, is,
IS the engine overheating,?
try a new rad cap, they are dirt cheap.
and, is the oil or carbon in the RAD neck, cap off , cold engine>?
is there water in the engine oil, milky dip stick end?
same with A/T trans? milk, or pink/red ATF.
is there steam going out the tip of the exhaust pipe on a fully hot engine>? yes/no?
is air and water exploding in to the side expansion tank.?

cold engine
remove rad cap'
fill rad with 50% AF.
new cap back on.
put 50% AF 1/2 way up in to expansion tank(its marked clearly)
start engine , does it overflow now>?

How to replace a radiator on a 2003 mitsubitshi lancer es

make sure the engine is cold , drain the coolant from the rad ,there will be a drain tap/bolt on the bottom of the rad ,be sure to us a container to collect the fluid as should'nt be left to run down a drain etc as is very toxic,disconnect the top and bottom hoses, there are usually two bolts either side of rad loosen these, rad may lift out if not remove the bolts and lift the rad away and out of vehicle , if the cooling fan is attached to the rad remove , will be obvious what bolts need undoing, replace this fan unit on new rad ,then refit new rad , reverse of removal , dont for get to check the drain plug is closed on the new rad , refill cooling system by adding coolant to the expansion tank, run the engine and bleed the air from system ,there will be bleed screws at various points around cooling hoses etc , allow engine to cool 1 hour min ,check coolant level top up and repeat bleeding process as neseccary good luck very straight forward job , keep me posted

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.

On a 2001 infiniti j 30t..Change the radiator and would like to know how to bleed it or how to get the air out of the cooling system.

remove the cap on the expansion tank,undo the clip on the highest water hose and fill into it....then fill the exp tank...start up to max temp and any air in the top of the rad should vent into the expansion tank.

Water come out from Water line when Engine Shutdown.

Does it show signs of over heating at all? When cool, take off rad cap & check level in rad & top it up. If down a lot, start engine, turn on heat & let run until you hear rad fan come on & check temperature gauge to see if normal operating temperature. Let it come on a couple of times, and top up rad an inch or so from top, then put rad cap back on. Top up bottle to proper level & try it. If it spits back into return bottle, try replacing rad cap.

Losing coolant thro the expansion tank at a rapid rate, 4 litres after 40 miles, no visable leaks, rear heater pipes replaced and new rad and water pump

Not too familiar with this model but.... First some questions! Has the fault started after the pipes & rad replaced or were they replaced to remedy problem? If fault happened since work then i'd suggest an air lock in the system in which case you will need to 'bleed' the system of air. Make sure the expansion tank is the highest point & look for any bleed valves on the hoses - usually near the heater matrix. Sometimes it may be necessary to help the process by removing the temperature guage sender unit to allow the air to escape as air cannot pass through a closed thermostat. If the fault was there before, does the expansion tank seem to build up pressure very quickly? Do lots of air bubbles appear with the engine running & the pressure cap off?
