#65 of 561 Question on my Nissan Pathfinder 2002 by jxu158 Jul 18, 2005 (7:18 pm)
Recently, I notice that after I drive hime from work and parked for a while, there is some water under the car on the passenger side.   That "water" seems to be not the coolent, because the color is not kind of light green (the coolent color); when I touch it, it does not feel like some oil based. Basically, it seems like just be water... And my coolent reservor is on the driver side. In addition, seems, just seems to me there is no coolent leak from the radiator or coolent reservor, because coolent reservor is at its max level.   So I wonder whether it is a problem? Because the warranty period will expire in about 2 months, I don't want to wait until next oil change to get it checked.   I appreciate any help here.

Replying to: jxu158 (Jul 18, 2005 7:18 pm) It's probably condensate from the air conditioning system.

#68 of 561 Think my cooling system might be causing a passenger floor leak by sally3 Jul 21, 2005 (8:38 am)
I've had a leak there for some time. I can't trouble shoot it for the life of me because (I'm in Oregon) so it does rain alot, but it doesn't consistently leak when it rains. On the other hand it POURS water from the corner under the dash near the firewall when I run the AC. BUT I run the AC all the time throughout the year and it only seems to do this in the summer. I'm really not sure why this is happening and have had it looked at before. There is no consistency to the issue and so it's very hard to make a determination about why or when. Please help me. I've read thru all the water leak posts and don't see anything similar. I do not believe it is an exterior seal or door leak at all. I can actually watch it either drip or pour from the area in question. Replies to this message: Mr_Shiftright (Jul 21, 2005 3:36 pm)

Replying to: sally3 (Jul 21, 2005 8:38 am) You should remove the windshield cowling (under the wipers) and inspect for clogged drain holes (easy, just pour water down there and see if it goes onto the ground through a drain, or into your car)---also check the little drain tube that is supposed to drain off the condensation from your AC evaporator---on some cars it is buried so that might take some doing.
#70 of 561 red clay like stuff in radiator by angieatky Jul 23, 2005 (6:59 am)
I have had my car about 4 months and now there is a marroon colored stuff coming out the radiator I check it everyday and it is always a little low and has this stuff. It is thick too. It smears like paint when I touch it. I was just wondereing if it was stop leak and if I flush it out I'm gonna have a hole somewhere. I think it keeps me from filling it all the way up. And thats why its low everyday. Replies to this message: Mr_Shiftright (Jul 23, 2005 9:05 am)
#71 of 561 coolant light flashes by jerryg2 Jul 23, 2005 (7:47 am)
I have a 1998 Pontiac Trans Sport. The low coolant light came on, I added coolant, light went out for awhile - now the light flashes, Did not overheat and does not overheat. Replies to this message: jerryg2 (Jul 24, 2005 8:54 am) Mr_Shiftright (Jul 24, 2005 8:56 am) jerryg2 (Jul 24, 2005 11:14 am)

Replying to: angieatky (Jul 23, 2005 6:59 am) You should have that checked right away. Could be automatic transmission fluid (your radiator cools your transmission, if you have an automatic). If this is it (just a long guess), that would require a new radiator, and flushing the cooling system and the transmission. Do NOT delay. Find out what this is.
#73 of 561 Overheating on 1998 Sable by southie Jul 23, 2005 (10:31 am)
Recently I flushed the cooling system and changed the thermostat because the indicator was high. It remained midrange until I did serious highway driving. It then went high again. There is proper amount of coolant, in proper mixture, the cooling fan comes on at the right time. Any suggestions? Replies to this message: Mr_Shiftright (Jul 23, 2005 11:20 am)

Replying to: southie (Jul 23, 2005 10:31 am) Okay, overheating at highway speeds only indicates a circulation issue, not a fan issue, since the air flow at highway speeds should be enough to cool the engine even with little fan action.   So you have a clog or air in the system would be my guess. Some cooling systems require an air bleed procedure that must be followed---don't know if this is the case with your car however.
