overheating confusion PLEASE READ THIS! by jweav

i have a 1995 acura legend w/ 160,000 miles on it. i recently bought the car from a friend and i really love my car... but only weeks after i bought it, it started overheating. at first it was only one time and then it didnt over heat for about a month &1/2 and then, again, i looked down just intime to see the temp. needle rise to one mark under red line hot. since this i became much more aware that there is a problem. i was low on coolant and realized that it would be low more often than it should be. this problem got progressively worse and this week my car has over heated several times so, i replaced the radiator cap, checked the thermostat, thought maybe i have a leak in the cooling system but now im thinking its something different. one thing ive knowtest is the coolant in my radiator doesnt have much circulation, it bubbles a little, but i dont see much flowing...im now thinking its the water pump. i also dont think it is the cooling fans because they work, but when my temp. is hot, it seems they dont come on when they should?!?i dont have any leaks in my radiator that i know of... and im pretty sure that its not a blown head gasket. if any one knows of or has any suggestions, i would appreciate it very much!

I believe the water pump is driven off the timing belt and the belt needs to be removed to get at it. This is why most people will replace the pump when they get a timing belt change (about every 90K or so) since the timing belt job is a bit of a chore, to say the least.
 
As far as the overheating, this does seem to be the achilles heel for Legends. Too many people on here have gone crazy troubleshooting lazy and/or dead cooling fans. Most have either given up, replaced them, or rigged up a manual switch to turn them on and off. Checking into any cooling fan anomalies would probably be a prudent course of action in addition to checking the water pump. Good luck.

thank you very much for reading my messege. i have pondered the waterpump being my problem, but again i am thinking it is something else. i talked w/ a guy yesterday and he said something about a heat sending unit that goes to my electric fan... do you know if this unit was mal funcioning if my fan would still come on but not when my car is over heating? also i got to thinking, and the only time my car overheats is after driving the highway and then coming back into town... and it will not over heat when i sit and let it idle...if my waterpump was going out you would think the car would over heat everytime i started it...yes i am going crazy troubleshooting this problem... any input is very appreciated and thanks again for the reply.

denisem.....my car is a 95 legend w/ 160000 miles. my car is doing the same as yours. i also have replaced all of these things and checked all of these things. if you ask me we might want to drive our cars off a cliff just kidding anyways, my front fans are also not comming on, so i decided to replace the temp. sensor, well that didnt fix the problem, my fans still will not come on... it seems every time i think i know what the problem is, something happens to prove that theory wrong! i dont have an answer for your problem, but i really do feel for you. it seems the troubleshooting for this problem is enough to drive a person crazy! if you have figured out what is or was wrong w/ your acura legend, PLEASE LET ME KNOW!!!!! i would appreciate it very much.

ok here i go ,
i bought a 1989 acura legend coupe 2.7 v6. one owner garaged kept.
all service was up to date except the t-belt was due.
 
so i got my mechanic to replace t-belt, w-pump, valve cover & side cvr gskts.
cost me $512.50.
when i left the shop i noticed a vibration in steering wheel and the dash.starts about 35 mph and smooths out about 60 mph.
did not have this problem before so i took the car back. the mechanic looked the car over and started it up ,put it in gear and power braked it in drive and reverse.
 
he said that the frt & rear mounts were worn and needed to be replaced.he said they were causing the drive axle to bind. he also balanced the frt tires to be sure
it wasent them.
 
my question is- i know that the right front mount/strut/ has to be removed to access the t-belt frt. cover. and according to my manual it says that if any mounts are to be replaced the bolts on all mounts should be loosend for the engine to sit level.
and they are to be retightened in a specific order. if not it can cause a vibration.
the car does not vibrate in park or nuetral , it does vibrate worse on hills.
 
is it possible that a bolt could have been left out of compressor or ps pump or atl brkt.or one of the sprockets miss aligned that the t-belt goes around,
 
 also the t-belt tensioner was ok so they did not replace it,
 
 so do they have to remove all gears and or sprockets to remove belt ,or just the waterpump.
 
any way after reading your forum i ordered a new all metal radiator because of overheating problems with the plastic tanks.
 
thanks for your reply, blaza

A leaking waterpump is going to cause your coolant to run low and your car to overheat all the time, regardless of highway runs in between or not. However, the pump will obviously leak more if you are on the higway, leave you low on coolant, and cause an overheat situation real fast. A failed waterpump can leave your coolant level the same but still give you an overheating problem.
 
As for the sending unit, since you said you were losing coolant I would worry about that. Having the fans not come on at the right time is one thing, but it doesn't account for coolant loss. Having these constant overheats puts you in very real danger of causing some expensive headgasket damage, especially with these engines. Try to track down that coolant loss!
 
good luck

head gasket worry!? by jafo45

I recently purchased a '94 GS sedan with 104,000. Service receipts show head gaskets and new radiator at 84,000. Timing belt and water pump at 92,000. I am becoming concerned as I see so many posts regarding blown head gaskets. I'm wondering what precautions, preventive maintenance, driving habits etc might I observe so as too avoid having to deal with this problem in the future ?
 By the way I love this car and pretty much everything about it. I would hope to keep it for some time. Thanks MV
