The biggest problem with the 3+liter honda engines of old is the weak head gaskets used on them..very rare you dont find one smoking or over heating..while the car is cool remove radiator cap and look for trace of oil.then start car with cap off and look for air bubbles.if either then its a bad gasket

Try bleeding coolant system there,s a 12 mm screw on the top radiator hose housing on the engine while the car is running loose that screw until anti- freeze pour out then close it

After you check for the head gasket engine death, you may have a thermostat stuck in the closed position. When you replace the $20 part position the bleed hole up (or drill a bleed hole) and check for the cap keeping the coolant under pressure. If the fans don't go on try turning on the air conditioner. That will make at least one fan operate. I hope your radiator hasn't sprung a leak.

95 acura legend, if I install a air separator tank thru the bleeder valve to relieve the trap air ,will it affect the thermostat operation?


Let me guess. Some mechanic told you to do this to your Legend? :-)
Do not do this (if it's even possible)

The simplest thing you need to do for the Acura Legend is to bleed the coolant system to get rid of the trapped air.

1994 Acura Legend LS 6-spd. Idle Surging RPMs High & Low and doesn't stop after starting. Continues to do it at each stopping point?


you have air in your coolant. This is a common problem that causes surging idle on the Legends. You need to bleed the cooling system. Have a read here

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,

How do i bleed coolant system on 1994 acura legend?


USE THE GENERIC METHOD BELOW WORKS FOR ANY CAR.
The generic method of bleeding air from the cooling system is to use a floor jack and raise the front of the car as high as poss, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the cooling systeml

93 acura continues to run hot, the bottom hose isnt getting hot. i have changed the thermostat.


this is caused by a leaking cylinder head gasket or air in the sytem, if u did not bleed the cooling system follow this procedure, it is generic for all cars.

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.

Car is over heating back boiling


My 1994 Acura Legend over heats. There isn't any coolant in the oil, nor white steam coming out of the tail pipe. All hoses are tight and no leaks are noted. The fans are working properly. However, there is back boiling in the radiator and loss of coolant...

What is causing this ?
