Did you also change the thermostat while you were doing the rad? The thermostat is the most common cause of engine overheating, it should be changed every couple years whether it is acting up or not.

SOURCE: 96 Blazer Overheating

Yes the issue is most likely an air block, jack the front of the truck up as far as you can, fill the recovery bottle and run the engine for about 10 min, then shut down and run cold water over the radiator, this should purge the air, recheck the recovery tank and refill as ness.

Your radiator fan stopped working maybe a blown fuse bad relay or radiator fan switch.When you drive the car get air and cools down when you are in park the fan is supposed to provide the air if needed but its not working. However the fan itself could be burnt out and may need to be replaced. Good Luck

SOURCE: 1995 toyota lucida i have replaced radiator but

The engine is kept cool by a liquid circulating through the engine to a radiator. In the radiator, the liquid is cooled by air passing through the radiator tubes. The coolant is circulated by a rotating water pump driven by the engine crankshaft. The complete engine cooling system consists of a radiator, recovery system, cooling fan, thermostat, water pump and serpentine belt.

Check the coolant level in the recovery bottle or surge tank, usually mounted on the inner fender. With the engine cold, the coolant level should be at the FULL COLD or between the FULL HOT and ADD level. With the engine at normal operating temperature, the coolant level should be at the FULL HOT or HOT mark. Only add coolant to the recovery bottle or surge tank as necessary to bring the system up to a proper level. On any vehicle that is not equipped with a coolant recovery bottle or surge tank, the level must be checked by removing the radiator cap. This should only be done when the cooling system has had time to sufficiently cool after the engine has been run. The coolant level should be within 2 in. (51mm) of the base of the radiator filler neck. If necessary, coolant can then be added directly to the radiator.

While you are checking the coolant level, check the radiator cap for a worn or cracked gasket. If the cap doesn't seal properly, fluid will be lost and the engine will overheat.

Worn caps should be replaced with a new one.

Periodically clean any debris; leaves, paper, insects, etc. from the radiator fins. Pick the large pieces off by hand. The smaller pieces can be washed away with water pressure from a hose.

Carefully straighten any bent radiator fins with a pair of needle nose pliers. Be careful, the fins are very soft. Don't wiggle the fins back and forth too much. Straighten them once and try not move them again. It is recommended that the radiator be cleaned and flushed of sludge and any rust build-up once a year. If this has not been administered within the stated time, this may be why your vehicle is overheating at this time. Have the Radiator flushed asap if this is the case.

Now, if the coolant level is proper and, the cap is in fair or good condition, i would advise to move in the direction of the cooling fans and sensors as well. These fans are vital to the cooling process as well. The cooling fans must cycle in intervals to keep the coolant cool during stop and go driving or, long idle. They are also very important during the operational period of the AC during travel as well. i recommend inspecting the cooling fans while the engine is running. they should cycle during the running period. if this is not the case, you will need to test the operational value of these devices. The test procedure follows below


TESTING


1. If the fan doesn't operate, disconnect the fan and apply voltage across the fan terminals. If the fan still doesn't run, it needs a new motor.

2. If the fan runs, with the jumpers but not when connected, the fan relay is the most likely problem.

3. If fan operates but a high current draw is suspected continue with the following ammeter TESTING.

4. Disconnect the electrical connector from the cooling fan.

5. Using an ammeter and jumper wires, connect the fan motor in series with the battery and ammeter. With the fan running, check the ammeter reading, it should be 3.4-5.0 amps; if not, replace the motor.

6. Reconnect the fan's electrical connector. Start the engine, allow it to reach temperatures above 194°F and confirm that the fan runs. If the fan doesn't run, replace the temperature switch.



Ok, Now we will move on to the next possible issue. The water pump. ok, due to the fact that your pump is driven by the drive belt, you will need to start the engine and listen for bad bearing, using a mechanic's Stethoscope or rubber tubing.

* Place the stethoscope or hose on the bearing or pump shaft.
* If a louder than normal noise is heard, the bearing is defective.

Replace the pump in this case.

You will also notice leakage around the pump housing if the seal has failed as well. this will strain the impeller and, ruin the pump.

Now. the last area of concern will be the thermostat. this is the most common issue that will inflict overheating in many vehicles. The thermostat is used to control the flow of engine coolant. When the engine is cold, the thermostat is closed to prevent coolant from circulating through the engine. As the engine begins to warm up, the thermostat opens to allow the coolant to flow through the radiator and cool the engine to its normal operating temperature. Fuel economy and engine durability is increased when operated at normal operating temperature.


There are several ways to test the opening temperature of a thermostat.

One method does not require that the thermostat be removed from the engine.

* Remove the radiator pressure cap from a cool radiator and insert a thermometer into the coolant.
* Start the engine and let it warm up. Watch the thermometer and the surface of the coolant.
* When the coolant begins to flow, this indicates the thermostat has started to open.
* The reading on the thermometer indicates the opening temperature of the thermostat.
* If the engine is cold and coolant circulates, this indicates the thermostat is stuck open and must be replaced.

The other way to test a thermostat is to remove it.

* Suspend the thermostat completely submerged in a small container of water so it does not touch the bottom.
* Place a thermometer in the water so it does not touch the container and only measures water temperature.
* Heat the water.
* When the thermostat valve barely begins to open, read the thermometer. This is the opening temperature of this particular thermostat.
* If the valve stays open after the thermostat is removed from the water, the thermostat is defective and must be replaced.
* Several types of commercial testers are available. When using such a tester, be sure to follow the manufacturer's instructions.
* Markings on the thermostat normally indicate which end should face toward the radiator. Regardless of the markings, the sensored end must always be installed toward the engine.
* When replacing the thermostat, also replace the gasket that seals the thermostat in place and is positioned between the water outlet casting and the engine block.

* Generally, these gaskets are made of a composition fiber material and are die-cut to match the thermostat opening and mounting bolt configuration of the water outlet.
* Thermostat gaskets generally come with or without an adhesive backing. The adhesive backing of gaskets holds the thermostat securely centered in the mounting flange, leaving both hands of the technician free to align and bolt the thermostat securely in place.

SOURCE: how to remove the rear seat on 96 toyota avalon to

You do need to have a spring compressor. Get the McPherson spring compressor. It is a must. You can rent them at O'reillys auto parts, Kragen, maybe Auto Zone. To get a better understanding on how to change it out, I recommend a chilton 95-97 Camary Manual. Now I can't remember the exact tools you need but the ones I can remember are 22mm socket, 14mm socket, 12mm socket, for the 2 large stubborn bolts I had to impact drill them, and with that 12mm socket don't forget to take the brake line off the strut. When you jack up the car try using its stock jack stand if you dont want to bend the running bars underneath where you jack it up as the car is a unibody jacking it up too high will lift the cars whole side and you only need to jack it enough to take the tire off. The back struts require you to take out your back seat which are also easy to take out.

To remove the rear seat here a link, its on a 2000 but should be generally the same. I learn better with pictures anyway, hope this helps!

I Have A 96 Toyota Avalon xl 3.0 Car Starts And Dies!! Replaced Fuel Pump Fuesl Filter And Still Starts And Stops?


I'm not 100% clear on exactly what isn't working from your question other than now the car is starting and dying after changing the fuel pump. In that case it's possible you've oppositely attached the positive and negative wires to the fuel pump. Hope this might solve part of your problems.

My 1996 toyota avalon is overheating. There are no leaks, thermostat is new, radiator is new and has been flushed, changed the fan relay. Don't know why its overheating.


Is the fan coming on? If not, possible lower radiator fan switch/sensor? No leaks... So overflow tanks level stays stable? How do you know it is overheating? Elevated temp guage? Engine smells overheated? Both? We need more info.

1995 toyota avalon, overheating,just changed s/belt compressor stop working, now it runs hot. is this now a prblm with water pump or first thermostat?


I do not see a good connection between the serpentine belt and the engine overheating suddenly.

Perhaps you have a lot of burnt belt rubber on the water pump pulley?

Is the upper radiator hose hot? If so the stat is opening. If you start the car cold with the radiator cap off you can watch for coolant starting to flow and make sure the stat works...if the flow is low you have either a blocked stat or poor belt grip at the waterpump. Have you flushed the radiator recently? After 15+ years your car could be ready for a cleaning.

Where is the thermostat on a 1996 Avalon?


follow the upper radiator hose away from the radiator toward the motor and that is where you will usually find the thermostat housing.
