you could have a bad hose, check the upper and lower hoses and hake sure they are not caving in on themselves. sounds like it could either be that or you might have something cloging the hoses. run the engine with the hood open so you have the pressure build up, and look at both raditior hoses. see if they are bulging out as pressuer gets built, or if they cave in .

SOURCE: overheating losing fluid around intake manifold,is

If your loosing coolant then this is the reason for over heating.If it is leaking around the intake gasket then it could possibly be the intake gasket itself.What you should do is have the cooling system pressure tested.The throttle body gaskets were good for leaking coolant on these 3.8 engines.There was a recall on them at one time.Not sure if it would still be covered.You can call the dealership and give them your vehicle identification number and they will tell you if there are any open recalls on your vehicle.This would be a free repair on the throttle body only.Hope this helps.Good luck.

SOURCE: it loses power on acceleration and serious loss of power on hills

sounds like a clogged fuel filter. you need to have the engine pressure checked for leaks, you can rent the pressure checker at autozone, it connects to ur radiator and u pump pressure into the cooling system if u find water leaking around the head u know u have a blown head gasket. if ok then check the cylinder compression should beable to rent this also. it screws into the spark plug holes has a gauge on it. alternator problem w/ the light is probaly you need to tighten the belt.hope this helps!!!

SOURCE: toyota pick up overheating. Recently,

First thing that comes to mind would be a bad thermostat, either stuck or installed backwards. I've seen lots of bad "new" ones, try another before going too deep into this. Also, when does it overheat? Driving, loaded, at idle?
Make sure the system is bled, sometimes this is difficult and takes a couple heat cycles.
When you say reman. "heads", I'll assume that you have the V6 engine. These engines had problems with corrosion around coolant passages in the block. It's possible that even after doing the head gaskets, that combustion gases are escaping into the cooling system causing the engine to overheat. If you have the equipment, it would be helpful to plumb low pressure air into each cylinder at TDC to check if air is making it's way into the cooling system by watching for air bubbling at the rad filler.

Hope this helps,
Dave

SOURCE: 1994 Toyota Camry LE V6 Overheating, Steaming Engine--Blown Head Gasket??

It is best to be systematic about this. It could be either the water loss or the overheating which is the basic cause, either one could come first.

- there is a test for combustion gases in the water jacket, from a blown head gasket. This will very quickly cause overheating, and the excess pressure will blow the water out the overflow reservoir. If the car has already overheated and died, this is unfortunately quite likely

- the temperature sensor in the block may have failed. This will prevent the fans from running when the engine overheats, and you can see this. The fans are not driven by a belt. P68....

- the thermostat may have stuck closed. You will have to get it out and test it, but this is not difficult. See p328


http://www.turboninjas.com/camry/eg2.pdf


- this model of Camry has a plastic top tank to the radiator, which eventually cracks. Look there carefully.

- it may be that a radiator hose has gone soft and closed up. Check they are allowing good coolant flow.

- it could be that in a car this age that the radiator has silted up and is not allowing coolant through. Disconnect the top and bottom radiator hoses, when cool, and run water through from a garden hose to get some idea about that.

My car has a knocking noise when my car gets warm and looses power whlie driving.Does not have noise at start up only when I drive about 15 km the sound comes.


You say when it "warms up". The symptoms you are stating sound suspiciously like a serious overheating issue. The engine will clack loudly and lose most of its power when the engine becomes extremely overheated.

Mis fire on cyclinder one and overheating for an 2005 Chevrolet equinox


You are describing the classic symptoms of a blown head gasket from the cylinder into the water jacket. This causes loss of compression in the affected cylinder and also injects hot gases into the cooling jacket resulting in overpressure and overheating of the coolant. Perform a compression check of all cylinders and if any are appreciably lower than the others, you are looking at some major engine work.

My 2003 Ford focus blew a head gasket a while back. I got fixed that, changed out the water pump, thermostate, water resevoir, and a few hoses. It started to overheat again, but the thermostate wasn&#


If you got a blown head gasket, water is getting mixed with your oil, pretty much ruining it, and your oil's viscosity will be affected, causing oil pressure to drop and your light turns on.

How do you know your car is overheating if it's not showing in your gauge?

When replacing blown gaskets there are a few things that is best to do, like sandblasting the heads, clean, scrape block and use proper torque an sequence, only removing old gasket and placing new ones won't fix the issue, those gaskets go through extreme conditions, expansion, temp changes, etc, they need to be put mindfully. I mention this because it seems you changed a lot and ended up with the original issue...

If your gasket is blown you need to fix that asap, then identify where is your coolant leak/blockage that causes alleged overheating, doing a coolant flush might help. Good luck.

Overheating, no heat.


Sounds like you've got either a cracked head or blown head gasket now; this will give you your poor performance. As for what caused the overheating in the first place; you need to check out. Water pumps commonly go out, allowing the antifreeze to leak out, causing your overheating, or even heater cores. Once you got it hot, it warps the head, and blows the head gasket. More than likely, you also have white smoke coming from the exhaust, especially when you first start it for the day. The biggest worry, is if your head is warped too much, and if you have excess blow-by from the piston rings losing their strength from getting too hot.

I just got the water pump and timing belt replaced on a 2002 Hyundai Santa Fe v6 because antifreeze was leaking from that area and the SUV was overheating- i didnt let it get too high and it was leaking...


Could be intake gasket, head gasket or leaking bolt that didn't get sealed. You can use sealer but sometimes it does more damage then good. I don't use it on any vehicles that come in because of sometimes plugging more then it should, like the radiator and then causing over heat issues. But you can try it if you wish.

Loosing coolant somewhere.


it is the head gasket. you're wise to change the oil right away but stop driving it before you do some real damage to the motor.
