If you're getting five volts to the sensor, then there is an open in the circuit somewhere...either the sensor is unplugged or a broken wire somewhere...locate the sensor, follow the wiring harness and if you can't see nothing, take it to your mechanic...the over heating issue, could also be an air pocket in the coolant or something as simple as the wrong type of coolant in the system.

95 Acura legend LS,problem with engine overheat. changed radiator,thermostat,& most of the coolant hoses.however,the trapped air in the coolant has progressed,I was told to put a AST tank.Any thought?


Most modern engines have a degassing facility and sometimes those small ports and hoses block with silt and the small amounts of gas the head gasket has failed to seal will build up in the cooling system, displace coolant and perhaps disrupt the proper operation of the thermostat. Degassing is required to allow the gas to escape harmlessly to the space above the coolant where it eventually vents.

When a failing head gasket allows too much gas to pass into the cooling system even the degassing won't be sufficient and the thermostat operation is likely to be affected causing overheating and excess coolant displacement.

My thought in response to you mentioning trapped "air".

My 1989 acura overheated and now go thru alot of oil


There's not much you can do short of fixing the engine.
When it overheated, the metal in the cylinders may have warped, and the head gasket may have started leaking.
The oil is being burned thru the cylinders and out the tail pipe.

I have a overheating problem with my 1993 acura legend and i just replaced the thermostat and the radiator. the fans work fine there is no leak and there is no head gasket problem but it keeps on taking...


How do you know that the head gasket is good? even with a bad thermostat it would not overheat in 3-5 min, a bad fan or relay would not make it overheat so fast , this sounds like a bad waterpump that has a bad impeller that does not circulate the coolant , but would not take coolant , if you are going through coolant and overheating that fast i would say head gasket but if you were not loosing coolant i would say to check the water pump impeller, i have seen them rust away or break,

1993 Acura Legend Overheating.


This could happen if your fan is indeed weak.  To test disconnect the thermostat of the radiator by removing the terminals near the radiator hose towards the engine.  You should see the fan run at its highest speed, then you can check if your fan has weakened.

Ding ding ding ding! You guessed correct, the head gasket is bad. The usual sign for head gaskets gone bad is coolant mixing with the oil on the dipstick but not so on some of the overhead cams. I just finished tearing my 91 acura down after replacing two themostats as advised by a "mechanic with 20 plus years". Its not the water pump I'd say. Its a tough job to do but a possible one if you have some know- how and a ton of patience. If you are going to replace the head gasket, you may as well do the timing belt, waterpump, and the three drive belts. You're half-way there with the motor tore down. Its VERY expensive for a repair shop to do and you may want to check around before getting it done.

1992 acura legend very weird problems


This particular model suffers with head gasket problems. I have had to replace head gaskets on several of these vehicles to solve the overheating problem. The two cylinders in the rear of the engine are the problematic ones. The head gasket goes bad in that area which sends combustion gas into the cooling system. This then creates air pockets which in turn causes the engine to run hot. The air pockets then shift and as water starts to circulate again, the temperature goes back down. This cycle repeats over and over.
Solution is to replace the head gaskets.
