Bleed the air out of the cooling system. You cannot get all the air out have a radiator shop use a pressure bleeder for the job.

when bleeding the system to get the air out, you may want to turn of the heater to help get all the air out of the system.

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.

SOURCE: My 1994 Acura Legend keeps running hot. Gauge

When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.

===

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

SOURCE: Im having isues with my 1994 acura legend over

check and bleed your coolant. take of radiator cap, start the car witht the heat on defrost and set to max and let the car fully warm up to operating temp adding coolant to radiator as needed. If that doesnt fix it then change your thermostat. $20 part from autozone with gasket. to do this: follow upper radiator hose to motor, where it connects on is your thermostat housing, unbolt the thermostat housing and replace thermostat. Simple procedure but do it when the car cools down or you'll burn your hands with coolant (which will pour everywhere when you take the hose off) after that is done, rebleed system and add coolant as needed. not hard to do at all

I have a 1993 Acura Ledgend. For some reason my heater does not continue to blow hot air, it does for a few minutes and then begain to blow cold air. It does this often now. It works and then it blows cold...


first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure

Changed thermostat,flushed radiator,fan comes on but it takes a long time,car temp guage goes all the way up to H(hot) until i turn heater on full blast then goes back to normal temp????


have you try to change oil? some times engine heat does' not just come from malfunctioning of the cooling system . But sometimes its the oil that runs to the engine . if the engine oil is dirty already it could also cause the engine to over heat. do to change the engine oil of your Acura Legend.
