Question about 1993 Toyota Camry V6

1 Answer

Camry 3 litre v6 engine: Coolant in radiator bubbling profusely.

1996 model. Engine temp spikes quickly and coolant is blowing away (out the overflow plastic reservior mainly.)

Question: Where do I get step by step (with pictures) guide on the net on how to remove the heads?

Supplementary question: Can the heads be removed without taking the engine out of the car?

"Real problems", thanks.

    I appreciate the advice. At the time of receiving it however it was too late to run the motor; In my spare time I'd been at the car and throwing things pell mell out of the engine bay. Stopped after reading about the thermo and got it out. Tested it (only way I could think of) by putting it on the stove in water .. and near boiling it came right open unfortunitely.

    From a helpful site "Autozone" - be all at sea without it - managed to get enough info to get the timing belt job well underway and this has exposed the engine heads more at last. So I'll push on for now and trust to luck.

    Thanks.

If there is no white smoke billowing out of the tailpipe, I would not remove the heads. If you had bad heads or head gaskets, there would be a whole lot of white smoke pouring out of the tailpipe. Coolant bubbling into the overflow indicates poor coolant circulation...You may just have a seized thermostat, partially clogged radiator or malfunction cooling fans. Try removing the thermostat and running it. If the bubbling stops, you do not have a cylinder head issue.

Thanks for choosing FixYa for assistance!

Coolant not visable


do not ever run the vehicle and check the coolant, coolant will go everywhere. leave the vehicle off and make sure its cold and then open radiator cap if radiator and overflow are empty then fill the radiator full and fill overflow to the fill line. put the cap back on then start vehicle. if no leakes then you where just low on coolant.

2005 impala temp gauge not working light says overheating replaced thermostat temp sensor and bleed system. Any thoughts


Remove the radiator cap, let the car run. When the car is at temp. and the thermostat opens you should see coolant circulating in the radiator. If there is coolant flow and you know for a fact that the engine is not actually hot,(check with a laser thermometer: point the laser at the engine block and read temp.) then you more than likely have a problem with the coolant temp. sensor. Check the connections, replace the sensor.
If you do not see coolant circulating in the radiator then you have an issue with either a thermostat, water pump or possibly a blockage or at worst a problem in the head. Check the overflow with the car running, if it is steadily "blowing bubbles" in the over flow (like someone blowing bubbles into a cup with a straw) then there is compression leaking into the cooling system and there is a problem with the heads. Remove the heads and have them checked for cracks at a machine shop.
If there is no "blowing bubbles" then I would remove the thermostat, run and check for circulation in the radiator again. If it is flowing, then replace the thermostat. No flow, Check the radiator with a laser thermometer. With the car at temp. point the laser at different areas of the radiator and see if you have "cold" spots. If you do then you have blockage at the radiator. If you have consistent readings across the radiator that is not "cold" then change your water pump.
I hope this has been helpful and helps you to solve your problem.

I have a 1993 toyota Camry V6. I have replaced the air intake hose, radiator cap, air filter, thermostat, and coolant reservoir. Everday it still ovet heats. The water cames from the little overage hose on...


This could result from a thermostat which is stuck closed, or a failed coolant temp sensor not allowing the radiator fans to run when they should, but I think you have a blown head gasket. Overheating is a classic sign of combustion gases getting into the coolant. The pressure also forces it out of the overflow.


Warm up your engine a little, about half, and remove the radiator cap by putting a towel over it first. Then let the engine keep idling until hot while you look down the filler neck into the radiator......carefully.

If you see white bubbles like dry ice, that is a failed head gasket. If not, have a mechanic do a test for combustion gas in the coolant with a gadget like this

Radiator toyota camry 1998 v6


You may have

- a coolant leak somewhere, comes out when the engine heats up and pressurises the radiator. Camrys do develop a crack in the plastic radiator top tank, which can be hard to see if on a seam. Another place which leaks is under the intake manifold, which is not visible. There is a test, called a "leak-down" test

- thermostat stuck closed, preventing coolant circulation

- a leak through a head gasket from a combustion chamber to the coolant jacket. This will quickly cause overheating, and sometimes causes white bubbles in the radiator neck, like dry ice. There is a test kit available for gases in the coolant.

Heat is not working - coolant was low so filled it.... problem here... heard something about an air pocket


If you dont have an external coolant leak anywhere under your hood that has shown up on your driveway it could be the intake manifold or the headgasket leaking. Also check the thermostate to solve the heat issue.

My coolant expansion tank is overflowing after 20 minutes running


There could be a couple of reasons for this,

1. The thermostat could be stuck closed creating more pressure than normal. Your temp guage would show a higher temperature or you have another blockage in the system.
2. The expansion tank is too full.
3. The cylinder head may be leaking. If you fill the system run the engine to normal temperature with the radiator cap off, look for quite large bubbles coming out of the filler cap. If the head is badly leaking, they can be like a volcano. The temp will rise quickly from cold and the engine will overheat in a short distance.
It does seem odd that it would only spill over after 20 mins. Suspect that the expansion is over full first if your temp is normal. Let it run until it stops and see where the level is when the engine is cold.

My subaru 1996 250t non turbo over heats after running for awhile, radiator emptys out, dosent seem to have any holes/leaks but there is water on the underside of hood surgesting it coming out of radiator...


refill rad start car wait 3- 5 min now look in rad since you never put rad cap on

if low fill
if not low check temp gage if high them it's time for thermostat if reaching temp slowely make sure rad fan coming on
no fan ? check fuses and releys both good then it's a sensor and will likely require a quick trip to see boby da mechanic

Still losing coolant


Hi, Sounds like the water pump is not circulating the water, as soon as the engine heats what water is in it, it will boil. Since you are brave enough to open the radiator when it is hot ( Bad Idea ! ) open it when it is cold, start the car and watch to see if the coolant circulates. You may have to wait unit the thermostat opens and if the water pump is bad when the thermostat opens it may spray hot coolant and steam instead of circulating what is in the radiator so don't be in the way. Not the best way to test this but works if you don't have diagnostic tools. Good Luck! By the way, coolant means antifreeze mixture which if it gets too thin lowers the boiling point significantly.

Chevy S10 overheated, now heat doesn't work, leaking coolant


When an engine is overheating and then the temp drops on the guage, it's usually a sign that the coolant is not touching the temp sensor. There's no coolant in the engine. Putting water in the overflow tank won't solve this. Take the radiator cap off after the engine cools and put coolant in the radiator. you might have to crank the engine and do this several times, as the engine can develop air pockets that won't allow the coolant to travel inside the engine. If you don't see any leaks, and it still uses coolant, you've probably got a blown head gasket. Check for water on the plugs, check cylinder compression. If it slowly uses coolant, try putting a large box of pepper in the radiator or some of that radiator seal copper flakes.

There is a coolant leak in my 1996 chevy camaro. it has the 3.4 litre V6. I replaced the intake gaskets and still have a slow coolant leak into the engine oil? Could it be a head gasket?


Since you used a question mark after "engine oil", I assume that you're not too sure where the coolant is going. While it's certainly possible for the coolant to end up in your oil, you should be able to see byproducts of combustion in your coolant (a very dirty coolant) if the head gasket is leaking. It could also force coolant out of your overflow as you drive, but not while you are sitting idle, making it hard to actually see if this happening to your coolant. Check your coolant for signs of this "blow-by". If your engine is losing power, you might want to do a cylinder balance check.
