The over fill tank is usually connected via the neck of the radiator. This flow to this tank is controlled by the radiator cap spring/seal. If the overflow tank is actively having coolant pushed to it I'm willing to be the radiator cap is worn out. Try replacing it.

    I should also add that if the cap is bad, the system will not pressurize, nor will coolant flow properly, which will prevent your heater from working.

SOURCE: BOTTOM RAD HOSE COLD TOP HOT. ENGINE TEMP ABOUT

Did you burp the air out of the system after changing those parts? It sounds like the thermostat isn't opening which is why the lower hose is still cold. Click my screenname, go to my tips and tricks, and choose the one about burping the cooling system - it may help you out.

You probably never cleaned the cooling system out.

If you have not get it done by pros.

It seems something is blocking the flow. If the water pump went bad you will know. Rarely ever heard a impeller breaks off like you think. The bearings and the seal break first.

Check and see also if the heater valve is working.

As for the over heating even new thermostats fail. Reverse flush is needed or the procan measure the pressure in the radiator cooling system and edetermine if there is a engine pressure problem. Tools and experience is the key in the game of diagnosis.

the water pump and thermostat should have solved it. an air pocket can cause that but usually not to that degree.

don't get one of those cheap *** plastic impeller water pump for sissies. Get the metal impeller one. get a cool running thermostat and drill two 3/16" holes in it 180 degreess from each other. you may have installed the t-stat backwards.

SOURCE: antifreeze/water leaking . puddle underneath van

May not be either. Does the van run hot? If it doesn't then the coolant when it is heated is going to the overflow reservoir and if that fills up then out the overflow line to the driveway or the garage floor but everything is O.K.

Either you have not bled the system, or possible fan not working, or head gasket problem. Solution

Step by Step
1. Check both hoses, do both have equal amount of pressure?
2. Run the vehicle where your gauge shows in the middle, shut the vehicle off then open the bleed valve near the heater line and wait till fluid comes out like a steady stream. Make sure you do not go low on coolant.
3. Turn on vehicle, turn on A/C high maximum blow check to make sure both fans are on. We are testing to make sure the fans at least work!.
4. After all this and you are still boiling over make sure your radiator cap is good if not then replace. Last but not least get a block tester to test for exhaust gases in the coolant. Rent one from autozone. $25.00 plus fluid which is about $8.00.

Overheating but ive already replaced the thermostat water pump but still rung hot no water flow circulating need answers .etc


When its cold remove the rad cap, start it up, put your heater blower on full and full heat on, then when the engine gets hot look inside the rad you should see the water flowing. If its not flowing feel the top of the thermostat housing/rad hose it should be nice and hot, it its not your stat is not opening. Are you sure you got the correct temp stat for this car? Was it properly installed and is the system full with no air in it? You can also get a melt stick from your local Napa, making sure its the right temp stick for your car, put it on the stat housing and see if it melts. If it does and you still have no flow either its stuck closed, or its the wrong temp stat.

1997 Chevy Silverado 1500 heater has not worked since water pump was replaced


did you bleed the system. you have to run the vehicle with the rad cap off ,controls set to hot and keep it revved up to 1500 rpm.it should girgle inside indicating movement of water. top up and overflow the rad and close the rad cap.once the heat comes thru. if no heat then go after the thermostat.

Why is water overflowing my resivor on my pathy


If I understand correctly, your coolant (water) is overflowing out of your resevoir? Either you have too much coolant, and it doesn't have any place to go, or it is boiling over. Remeber even water expands when hot.

Flushed the heater core changed thermostat, water pump is good, changed fuse, heater was throwing heat but was over heating,checked radiator(flushed and added new fluid) now back to no heat


no, not special but you failed to stated engine, there are many engines.
and some are very tricky here, like 2.0L.
First state the symptoms,
your post states its overheating, then no heat. (why?)
old post. but others might
Ill post , overheating ,
Example if me, with overheat.
I see my dash gauge, show overheating and engine power drops and pings, then steam vents from the rad, cap?
Over heating (ill skip cab heater but on 2L this path blocked causes thermostat to go quite nuts. not posting engine, makes this hard.)
1: full of 50% AF (antifreeze)
2: new thermoSTAT they age and fail fast. so get a new one.
put STAT in with the wax slug down, and jiggle bleed pin forward.
get air out of system after filling, (RTM)
start car, and....
4: then using and IR pyro gun we then check that
the thermostat housing hits 170F min. but not too hot.
run motor till top rad hose gets too hot to touch 180f is normal.
I had to drive 10 miles, to get it up to 180F.
my car has the hotter, 195 STA,T so runs at 195f. (helps cooling)
USING the pyro gun , the top and bottom of each rad tube.
This tool is Amazing.... and saves burn hands.
if the bottom of any RAD tube is way less than the others?, that is
a clogged UP rad tube. solution is , NEW RAD.
Usually rad repairs, are more costly than new. IN USA.
The water pump must spin at full speed, belt tight.
The impeller or some suz, motors likes disappear. from electrolysis action. so not looking at the impeller is a FAILURE on the mechanic side.
if this car has 2.0 I-4 (4 banger) it has a coolant tube on the rear
of the STAT housing, this tube must flow coolant at all times.
if it dont, the thermostat , will go nuts.
nuts means, that insufficient flow passes the thermostat wax block
causing the thermostat to cycle in a wild and random way.
I dont like this design but is reality. If applicable.
post country, post engine type and state the symptoms.

Hi Mark, I've just had the same problem with my 2007 Sante Fe. After replacing water pump, radiator, thermostat, etc, turns out it was the cylinder head gasket. No water in oil, but engine pressurises the water system, blowing water out the overflow. Cheers

Engine heating up to overheating but no heat in car. Radiator fluid going to overflow reservoir


looks like your thermostat is sticking, and will need replacing,

this part is used when engine is cold so it heat up only a small part of the water jacket, once is warms up the thermostat opens and allows heat to car to warm you and keep the engine cool.

this is not a difficult job but messy and you will need to top up coolant water afterwards.

the termostat once removed can be tested in boiling water when cold and you should see it open if it does not it needs replacement and new gastkit and sealing.

best to have a qualified engineer do this job. is should not be too expensive.


I hope this was useful.

My BMW 318i has had a new expansion tank fitted after overheating and splitting.After bleeding the cooling system it seems as though the bottom hose is not getting hot any suggestions would be welcome


NORMALY THE HOT FLOW ENTERS THE TOP HOSE AND COOLER WATER LEAVE THE BOTTOM HOSE BACK TO THE BLOCK, SO IF THE TOP HOSE GETS WARM THEN THE RAD IS BLOCKED , IF NIETHER GETS WARM/HOT THEN THERMOSTAT NOT WORKING, OR YOU HAVE BLOCKAGE ELSE WHERE, SO REMOVE BOTH HOSES FLUSH RAD WITH HOSE PIPE, (WHEN ENGINE IS COLD) SEE IF WATER FLOWS OUT AT SAME SPEED AS U R FILLING IT, IF NOT ITS BLOCKED, 2ND REMOVE THERMOSTAT AND FLUSH ENGINE OUT, U CAN BUY RAD FLUSH/CLEANER AND TRY THAT,

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

Run engine from cool, with rad cap off & heater on heat (not AC) and watch for circulation through rad when engine reaches normal operating temperature. Rev engine slightly from time to time for a couple of seconds, to increase flow & help bleed air out of system. Let it run for a while, and watch for increased flow in rad 2 or 3 times. Probably see air bubbles at same time.Hot coolant from engine comes in top, and back out bottom to engine after cooling in rad. The increased flow in rad ,indicates thermostat is opening & circulating cooler liquid back into engine. After 2 or 3 times put cap back on & fill return bottle only to line specified as warm/hot engine level.
