I searched a bit but did not find specifically what I need.

At times if I run the fan (not A/C) ican smell antifreeze. It's fairly faint but still noticeable. Anybody ever have this problem and what was the problem/fix?

Any advice will be appreciated.

Thanks gents.

Back when my legend was overheating alot i could smell coolant all the time. Not saying that yours is overheating but that it could be caused by a coolant leak somewhere.

1) just an arm (unless you pay someone else to change it, then it'll cost two arms, a leg, and a firstborn.....)
2) must be replaced
3) BHG (blown head gasket)...(search on that if you dare!!!)

Question Is there a test ?

Can a mechanic test it without tearing the dash down to look at it? I did some more research. It's not leaking at the floor board (yet) and the car doesn't overheat. I have been watching the coolant levels. If anyone knows let me know. Bad thing is, I do some minor stuff myself but not much. i'm an electrician not a mechanic. I guess my mechanic will be happy to see me coming this time.

Let me know if anyone knows of a test?

Call the stealership. They will carge you 90$ to diagnose and give you a quote. Then you can call around to see if you can have it done cheaper. but if you decide to have it repaired by them, they will wave the fee. But remember, a peice of mind is peice of mind. The dealer will do it right the first time with a warenty. Personaly, I would look in the HELMS manual to see if i could do it myself.

Before you begin gutting the interior, first determine that it is the heater core. Have you had to replace coolant in the reservoir? If so, have you checked for visible seepage/leaks? Check to determine whether the carpeting on the passenger side is damp. Do you hear a slight "sloshing" sound in the ducts? Using your finger, do you detect an oily residue on the inside of the windshield in proximity to the defrost openings?

First, check to determine whether one of your radiator hoses is seeping. Next, see if you have developed a radiator core leak. You could also have a heater hose leak under the hood at the heater core connections or one of the hoses seeping. Another possibility is the block nipple to which a heater hose is connected seeping. Although never having been mentioned, yet another would be the coolant passage pipe (under the manifold - to thermostat base) developing pinholes. There is also an O-ring at the base end of the pipe. You need to check all coolant hoses. It would not be unknown to have a leak near the front and as you drive, the air flow directed into the cabin. With this in mind, check the water (coolant) bypass pipe located under the throttle body as well as the water pump and its hoses.

Many thanks

I'll check the hoses this evening and then try the stealership. I noticed this problem started very slightly after I changed the intake. I have not had to replace coolant. i have been watching the reservior. No visible leaks either. For sure there is no dampness in the carpet, no residue on the windshield so that makes me feel a little better. But my wife brought to my attention the change in my ashtray was pretty warm the other day. I wonder if that means anything?

Is the helms manual on-line where I can access it or do I have to go find one somewhere?
Many thanks again guys Any other opinions will be appreciated.

If you removed the intake, then I would recheck the rear hoses. I would also take a careful look at the water bypass inlet pipe (2 inch vertical pipe way under the throttle body) as it uses two O-rings which may now be seeping (they should have been replaced when the intake manifold was removed). You also need to check the hoses connected to the throttle body, esp under the throttle body. If during the intake removal, the thermostat base was also removed, the O-ring from the coolant passage pipe should also have been replaced.

I have never noticed atypical heat from the ashtray area. ? wrong replacement bulb.

Perform a Search for an on-line HELM. I believe one may be available. I prefer hardcopy. For a HELM Manual see www.helminc.com.
