All right, well I was out of town while my car was being inspected (my dad took it to the shop). Turns out my radiator has a hair line crack near the bottom causing it to leak under pressure. Because of this the mechanic did not do the BHG test like I asked. So I still donít know if I have the BHG... I am going to replace the radiator soon and I will keep everybody posted if this fixed my problem.
I've been gettin some cooolant leak around under the radiator, I took it to my local honda/acura specialist. They found no leaks or evidence of leaks. My car still occasionally leaks coolant. I haven't experienced overheating. My coolant levels is @ low. Any ideas? What could it be? What should I do? Take it to the dealers?

If you have read through allllll the post on this subject then you
have your answer. A leaking radiator is what.
It appears that when this radiator starts to leak there will at times be no visable signs of water except for maybe a very small
amount here and there around the the top and maybe the bottom of the radiator. YOU should not see water or evidence of water around your radiator top or bottom. It's that simple, you
have a leaking radiator.
The radiators installed on many cars today have a top and bottom made of plastic and the materiel cracks. Hair line cracks
for starters and the cracks barely open initially but get worse as
time goes by and more water leaks until you run low on water and the worse is coming very very soon. I am in the process of doing a radiator change now and prior to this my radiator didn't seem to be leaking and in fact I experienced the same symptoms as you explained above. I finally said to myself " self there should not be any unexplained water around the radiator and that is a sure sign of a leaking radiator or hose or something" Reading these boards really enlightened me about those funky radiators
installed on these Acuras.
There are some replacement radiators to be found on the net
but I would not go to Acura for sure. You can even find an all metal for this car for $ 118.00. I don't recall where at this time but maybe someone will pop up with the website.
If you read all the postings on these boards the subject has been
covered and covered and...
Well I got a phone call earlier today. My mech said that the head gasket was deteriorated and the cylinders were full of water. Tomorrow he's gonna take the heads in and get them check at the machine shop for cracks, warpage, lashing, etc...
facing in-front of the car
You see that the compression may not sound like a blown head gasket, but it is...
If you live in the northwest area (Tacoma-Seattle) I can hook you up with my mech. Him and his partner has 20+ years of experience on engines.

Yes, One of my friend is a mechanic works at Acura dealer. He now take care of my
car for me. The first time he checked on my car, he removed the metal clip (screw on)
in the middle of the back of the radiator.
He told me that the clip is used to support the small hose but over the time, the
vibration is known to crack the radiator and causing the hair line to crack and leak.
He told me NOT to put the clip back and the 2 little hose doesn't really need the clip to support them.
The process is: when the radiator leaks (bad radiatior design, unavoidable) then
the engine overheat and causes the blow out head gasket.
I replaced the radiator when it first started to leak (I kept good eyes on them)
and I never had any overheating problem.
On a 93 LS coupe, under normal conditions, when you turn the heat on should the warm air come out the bottom vents or the vents on the end of the dash? My car is not putting out a lot of heat and the air always seems to come from the end vents on the dash not the bottom vents near the floor. Is this correct?
It sounds like your coolant may be low, check the coolant levels first.
It is possible the coolant is low for any reason (leaky hoses, cracked radiator...) First check the overflow tank at the front right side of the car, you have to unscrew the cap with a black hose going into the top of the cap. (Not the winshield washer fluid cap, thats located directly beside it) Make sure there is coolant filling about 1/2 of that tank.
If the Overflow tank is full, remove the radiator cap (WHILE THE CAR IS COOL) and add coolant directly to the radiator until its full.
Another idea you might want to try is bleeding any air out of the cooling system.
::sigh::.....im starting to have heater core problems as well.... :-\....I figured it would catch up with me,....here is the situation.....I smell antifreeze in the morning when I turn on the heat,..passenger side carpet is NOT wet,...I cant say i've been getting an oily film on the windows....
wierd thing is,...NO LEAKS,..my car is dry as ever....nothing on the ground in the morning,...or anything,...nothing,...just recently I flushed the coolant out even since then i've been noticing wierd things....1. symptoms of Air in the system,...I bled it...it was good for about a week,...then,...while having the remote start on the idle started fluxuating....from 500-1500 rpm,....so I did a search and found it 2 be air in the system,...soo I took it for a hard spin and bled it a few times,....rpm's back to normal...everything was kool......NOW......2 days later...temp is shooting up when heat is on,....after the initial morning drive,.....then it settles out,...after about an hr,...the car is normal....heat will blow HOT....no smell,....temp back to normal,....!!....I think there is still gotta be some air in the system,...but ive spent the last 4 days getting rid of the air,....all while its 20 degrees outside!....ALSO....top radiator hose looks like its about to EXPLODE!......I notice if I take a 10 min drive then bleed the upper hose....air will come out,....guaranteed....just a little bit however, not much.....I have a feeling I've got air in the system somewhere,...either its getting in,...or it's already locked in there,.....
I have a feeling it has to do with a. either the heater core itself, or b. the heater core hoses.........I think it would benifit everyone on this forum,...if we posted more pictures of these hoses in general....with arrows indicating trouble spots,.....searching and reading words on a web-page can only go so far.....
I think I may have found my problem,...I drove the car around to build up some pressure,....then I sat and watched the engine,...I saw that the left side heater hose, from cole austin's picture is leaking water,.....I think that the system is leaking thru this hose,....what do you guys think???....is this feasable....??....also will replacing this hose restore the pressure in the system....????....oh yeh, the reason I'm not seeing any antifreeze on the floor is that it drips right onto the exhaust manifold and burns away.
I just replaced those hoses when I replaced my heater core. They are a ***** to get off. The one that goes to the engine block is extremely difficult to get the clamp off of. I did it over 2 weeks ago and I still have cuts oh my hands from doing it. The hoses are cheap, less then 20$ each at the dealer. No one else had them that I could find. Also, if you heater core is leaking it doesn't show up on the passenger side carpet, it actually pools up underneath the passenger seat, being that it is the lowest point on the floor pan. The carpet itself is also very thick, so it will absorb a large amount of the radiator coolant before it actually allows it to pool up underneath the seat. I have a 91 coupe so the floor pans may differ between the sedans and coups. I had to roll up the carpet and soak up all of the access coolant. I took pictures of it all, if some one is willing to host them for me. The total labor for replacing my hoses and heater core was close to 20 hours.
