Question: 1993 Acura Legend mileage:103,156 I think its engine is v6 and only when I'm stopped at traffic is when it starts to over-heat, I was thinking that it could be the fan?

Answer:  Check the thermostat, take it out run the engine without it, now go and duplicate the problem. If it is still overheating, the radiator could be partially plugged. Try flushing it first and if that doesn't work a new radiator may be needed. With that many miles, a water pump would be a good idea too.

Question:  1991 Acura Legend mileage: 135,000.  I recently had a water pump and a radiator installed.  The temperature gauge is dropping down into the cold area.  I have heard of the temperature gauge rising but never dropping.  What would be the problem?

Answer:  With a new radiator, there is a good chance your car will run cooler, especially if the old radiator was plugged.  If it running colder than normal, the thermostat may need to be replaced.
 

Question:  1993 Acura Legend initial symptom was intermittent blower control on all low speeds and always work on max.  Max speed failed and over the phone, the Acura dealer stated a bypass transistor was the problem.  Acura dealer installed bypass transistor with no positive results.  He then stated the blower motor was at fault.  Dealer replaced motor; again with no positive results.  He kept my car for another couple of hours and stated it was the blower motor/temp control unit in the dash and it cost about $1600.  I personally replaced the control unit from a salvaged auto with the same results.  You can hear the relays click but no blower motor working.   I removed the blower motor from the car and connected it directly to the battery and it appeared to work.  I reversed the leads and connected them again like original and the motor blew extremely hard.  I disconnected and connected the leads to the battery several times but could not duplicate the extremely strong air movement but it would always blow when connected.  What is my faulty component/components?  Any help/advice would be appreciated.  The car is in great shape except for that.  I would hate hardwire the blower motor but it is starting to get hot in Texas.

Answer:  In view of the amount of parts that you have replaced, what comes to mind that you did not mention would be the control switch on the dash.

Question:  1992 Acura Legend  mileage: 105,000.  This has been going on for more than a year, and I do all my own mechanical work so I don't have a regular garage mechanic to ask about it. Often when I depress the brake pedal at 45 mph or faster it pushes back in the pulsating fashion that indicates the antilock braking system is engaged.  The ABS warning light doesn't come on at any time.  And there's no problem with the braking.  But clearly, something's not right.  What's up?

Answer:  Check the brake rotors to see if they are warped.  This would explain the pulsating that you are experiencing.

Addendum:  Thanks, but I've been through difficulties with warped rotors before.  That was more a shimmy and shake in the front end when I braked at high speed.  In this case the brake pedal pushes back at me, pulsating, exactly/precisely the same as it does on ice or wet leaves when I put the ABS through its paces.

Answer:  Check the wheel sensors for the ABS; one is more than likely damaged or not functioning which causes your ABS to �think� one wheel is going slower than the other is.  This would cause the pulsing you described. 

Question:  1991 Acura Legend L 3.2 V6 mileage: 95,000.  For approx. 8,000 miles a 'rattling' noise occurs at 1,500 rpm - sounds like engine is a diesel.  Obvious when car is decelerating or held steady at 1500, it runs fine otherwise - gets 24 mpg highway 70-75 mph.  The dealer originally said it was carbon buildup and it needed GM Top Engine Cleaner.  After they did treatment, car started better but noise is still there - seems to be a little louder.  Dealer now says it could be rings but also says 'not to worry about it - it should be good for 200,000 miles'.  Any ideas on how to come up with a better diagnosis would be appreciated!

Answer:   We would check for a broken piston or wrist pin.

Question:  1997 Acura  mileage: 140,000.  How do I know if my alternator is going bad?  Also, how do I distinguish the difference between the alternator as opposed to the battery being bad?

Answer: A load test will tell you the condition of the battery.   The output of the alternator should be approximately 14 volts and 40 amps at 1500 Rpm.

Question:  1991 Acura Legend Coupe V6 mileage: 135,000. My daughter's car oil checks full but her car's oil light comes on and blinks.... could this indicate a oil pump problem or what?

Answer: Yes. You may be having oil pump problems. The pump relief valve might be stuck open. Several other possibilities are a faulty oil pressure-sending unit or the engine main and rod bearing are worn allowing the oil pressure to escape.

Question:  1990 Acura Legend mileage: 126,000. I've recently been told my Acura has a "seeping head gasket." Is this something I should have fixed quickly or will it be ok for a while? Any estimates on repair? I live in Connecticut.

Answer: It may be okay for a while if it is just seeping. Check coolant and oil levels often. You may want to consider an engine overhaul with 126,000 miles. Head gasket replacement would cost will vary

Question:  1998 Acura Legend  mileage: 155,000. My car's speedometer has been acting strangely lately. The needle would vibrate, as I get moving. The faster I go the faster the needle would vibrate. Around 60 miles per hour it would bounce back and forth around one dash. The funny thing is that it only happens sometimes. This is driving me crazy. Your help would be greatly appreciated.

Answer:  The speedometer is driven by a cable that connects to the transmission. The cable should be replaced. You can try cleaning and re-lubing the cable, that sometimes works.
