A laser thermometer can help get accurate system readings,
These 1991 to 1995 Legend V6 3.2L develop sediments in key areas from electrolysis that need to be reverse flushed out. Otherwise the pump heavily favors the bypass ports at the thermostat. Also foaming can occur there which destroys flow. Rude design problem. I use 1 pint of denatured alcohol to thin the water a bit for flushing. A baffle riveted to the thermostat can reduce bypass favoring and foaming for race application. I use 80 PSI air to force the water backwards out of the upper hose while the engine is still warm. White powdery residue when it dries will indicate some success. Head gasket leaks will over- pressurize the radiator and sometimes get oil in the coolant which will also smell like exhaust. Feel your radiator temperature at various areas while it is warming up to determine flow. OPEN YOUR 12MM BLEEDER ***** at the upper hose aluminum input tube to fill as there are lots of hiding places for air and this engine needs every drop of coolant.

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.

I have a 1996 Acura 3.2TL[V6] and it is overheating...


I had the same problem, whole new radiator, new hoses, new thermostat, and still overheating. What the problem was for me...bad radiator cap...all that money and a $20 fix...try it?

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.

95 acura legend doesn't overheat on freeway, but does on surface streets. I had the radiotor flushed and changed the thermostat.


First off, while the car is cold, remove the radiator cap, and start the car. Let it warm up, and make sure the fan kicks on, and make sure the thermostat opens up. There is no danger in doing this. The cap is off, so no pressure can build in the radiator or burst out. That only happens when you remove the cap when the car is hot.You will see the coolant flow throught the radiator if the stat opens. If the fan doesn't come on, I would say you need a fan. If the fan comes on, and the coolant DOES NOT flow, you may need a water pump, or by chance, your new thermostat is bad. Also, without flow, that could indicate the radiator is bad. Flushes are good, but not always right. If you wait again til the car is cold, take the cap off the radiator, and get a bucket to drain the coolant in by taking the bottom hose off. Stick a water hose in the top and make sure water comes out of your bottom port. Hope it all goes well.

Well, an old hose can bust for several reasons. Would assume that the temperature change from driving raised pressure enough that a weakened portion finally broke. As for the fans, check fuses and connections, then verify voltage going to the fan. If there is voltage and it is still not working, you have a bad fan.
