Question about Toyota ECHO

1 Answer

The water pump was recently replaced on our 2000 Toyota Echo and since then, the coolant system has been air locked. It continuously overheats and there is no heat in the interior of the car. How can we fix this problem?

SOURCE: 2000 Toyota Echo Coolant System Air Locked

check your heater tap in the engine bay ...they usually ran off a vacuum hose.
If the system was not bled properly..ie by filling the radiator WHILE the bleed screw is open you will get an airlock.
the bleed screw is usually on or near the thermostat housing.
The water level must be higher than the top on the engine (I use a piece of PVC pipe in the radiator filler to do this.)

Also make sure the thermostat is not stuck in the closed position.

1994 toyota pickup 4x4 sr5 v6 overheats after changing coolant


Sounds like your water pump may be not working, while vehicle is off try squeezing both upper and lower radiator hose you should be able to feel the fluid in the lines and the hose should feel firm and not squish all the way together. Make sure you used the right coolant orange vs green and mix ratio. after all this has been confirmed start vehicle and squeeze hoses again before they get to hot to make sure the fluid is moving and now hoses should be pretty hard to squeeze at all while the truck is running. if you don't feel movement of fluids or hoses are very squishy it could be a vacuum leak and worst case your water pump, hope this helps-

My toyota tarago overheats


replace the thermostat and refill with proper coolant, make sure that there are no air bubbles stuck in the system. If that doesn't fix it check your water pump, there is a small hole in most water pumps called a weep hole, if it is bad, then there will be coolant leaking out of said hole

Why does my car overheat and i get no heat in car


Have you recently changed your engine coolant? Have you checked your engine coolant? If you just changed the coolant you probably have an air lock in the system and it needs bleed out. To do this i would need to know more info about the vehicle. Another possibility you could have a coolant leak, IE the water pump, radiator hose, heater hose leak. with low coolant the radiator can't do its job and cool the engine. You could also have a broken water pump impeller. No impeller no engine coolant flow threw the engine and heater core.

Overheats after 5 minutes. Radiator recently replaces.


Most probably when the radiator was replaced it was not filled properly and you have an air lock in the system preventing water from circulating properly.
Read your owners manual or go a forum on your partcular car there as specific methods of adding coolant to assure no problems. Some systems even have a bleeder.
Other possible problems would be a collapsed hose or a bad thermostat.

2000 Chevy Silverado normal operating temp is 210 , recently temp rises to 250. Its been this way for a few days, common operating temp is around 240-250 now, but does not overheat. Coolant levels are...


250 TOO HOT FOR ENGINE AND TRANSMISSION. SOUND LIKE COOLING FAN CLUTCH BAD ITS FREEWHEELING NOT LOCKING UP TO DIRECT DRIVE TOO COOL ENGINE OFF BECAUSE THE FAN CLUTCH THERMOSTAT NOT WORKING THE HOT SILICONE OIL CAUSE IT TO EXPAND TO PUT RESISTANCE ON CLUTCH TO PUT DRAG ON FAN CLUTCH CAUSING IT TO LOCK IN GIVE IT DIRECT DRIVE.I WOULD STILL REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP IF TEMPERATURE STILL 250 DEGREES YOUR RADIATOR AND COOLANT SYSTEM NEED FLUSHING.

1990 SUBARU OVERHEATS WHILE DRIVING


1990 Subaru overheating condition.

The entire cooling system needs to be checked.

1. If the coolant level is fine - and low coolant level in your cooling system is not the problem - you need to investigate further.(see 2 below)

If the coolant level is low it needs to be topped up with the correct spec coolant and then the cooling system checked for leaks which could be faulty/worn hoses and/or a leaking radiator. If the car continues to overheat after running with the correct coolant level refer to 2 below.

2. If your coolant level is fine the entire cooling system needs to be flushed out and replaced with new coolant of the correct spec. ( If this has not been done for a couple of years it should be routinely carried out in any event every 2 years regardless of any problems).

Whilst this is being carried out the thermostat needs to be removed and checked. If it has not been recently replaced, a new one of the correct spec should be fitted. It is possible that the overheating is being caused by a sticking thermostat which is impeding coolant flow between the engine and the radiator once the engine warms up.

At the same time the water pump should be removed and inspected. If the pump has never been replaced or has not been replaced for many years it is on it's last legs. A faulty/corroded water pump will be unable to flow sufficient coolant through the engines cooling system from/to the radiator and the engine will overheat.

Any old or tired looking rubber hoses (radiator and heater hoses) should be replaced while this work is being carried out.

When the servicing is completed and the new coolant added, the system will need to be bled of air. If this is not done air in the system will impede coolant flow and the engine will overheat. The entire system should then be checked for leaks.

Do not operate your vehicle whilst you have this overheating problem except to get it to the nearest reputable auto service center. You can do very expensive damage to the engine if running it overheated .

I HAVE A 93 TOYOTA CAMRY LE V6, THAT HAS A WATER PROBLEM, THE WATER KEEPS GETTING VERY HOT, ENGINE PUSHES THE WATER OUT TO THE COOLANT RESERVOIR, LEAVING MY RADIATOR DRY. I HAVE REPLACED THE THERMOSTAT AND...


These engines will overheat for many reasons. >>make sure there is no leaks at all, as air will cause the system to overheat while losing coolant at the same time. Depending if the radiator is original or after market, there may be TWO radiator caps (one on the engine and one on the radiator)- the one on the engine usually is faulty because of direct engine heat to the seal.>> On the thermostat housing, there is an O-ring at the end of the feeder pipe, usually leaks especially if the thermostat was replaced and not the O-ring. >>Check also the hydraulic driven radiator fan>>Check power steering fluid for proper levels first. unplug the switch atop the powersteering pump, start engine, rev to 2000 rpm (fan should increase in speed-you should hear it) if not it may be faulty.>> Check system for proper flow- With engine cold, remove the engine side radiator cap and rev the engine(1000rpm) slightly, notice if the coolant is flowing. If not, possible faulty pump, or clogged radiator. Hopefully this helps
