2004 GMC Envoy Radiator Cap Leak, Image: OP

Dave writes:

Hello Sajeev,

I have a 2004 GMC Envoy, 4.2-liter six-cylinder, with about 123k miles that seems to be leaking coolant from somewhere around the radiator cap. Every time I come to a stop with the windows down or pull into the garage I can smell antifreeze. The radiator appears full and the reservoir seems to be maintaining a fairly consistent level of the pink stuff. It never leaks enough that I see wet spots except now and then around the cap, and even then it’s only a few drops at most. I’ve taken it to the mechanic; they double checked all the hoses and connections and even replaced the cap, but it didn’t help.

I replaced the cap a second time thinking I got a bad one, but the smell remains. By happenstance the cap I bought happened to be the exact same brand the mechanic used. I’ve attached a picture of the engine bay showing the areas where I can see dried coolant. The perplexing part to me is that, judging by the splatter pattern near the oil fill and the air filter box, some of the coolant seems to be making it to the fan. Still, I never see any wet spots leading in that direction. Do you have any suggestions?

As a side question, I have been getting an intermittent CEL with an associated P0526 code (fan speed sensor). It will come on for a trip or two and then go away on its own. Any chance the supposed coolant hitting the fan could be causing the CEL?

Sajeev,

My new wife brought to the marriage her ’07 fleet-queen Taurus. She’s not a car pamperer by any means, but she does change her oil. This car got flogged like a racehorse in its previous life. Its body tightness is well-nigh gone, it unpredictably emits a strange unidentifiable groan from the depths of the dashboard center on moderate acceleration, the dime-size floormats are practically ground into dust, and the trunk barely agrees to open even when unlatched.

Sajeev,

I’ve got a 2002 Cadillac Seville with the infamous Northstar engine. I bought it nine years ago and at the time it was four years old and had 30K on the clock. Before I even ask, I’m sure you can already guess what happened. At 149,000 miles the head gasket issue has reared its ugly head. For those readers who are unfamiliar, the repair requires the engine and cradle to be dropped, stripped down, and re-studded with twenty new holes. As opposed to timeserts, this fix is usually permanent. (Read More…)

Best from the West, young man,

The Boss has a pretty nice ’94 Escort LX wagon sourced by yours truly, and it happens to have found the sweet spot betwixt my picking it and her loving it. A grand for this one-owner handshaker and she’s managed to put about 23K on it in the last year — points of interest are far and few between here in Wyoming. (Read More…)

Sajeev,

I am facing a problem with little real consequence, just more looking for advice.  We have a third vehicle, one that isn’t really used much and was purchased for $1400 a couple years ago to serve as a backup when/if one of our primary vehicles was out of service (A 2005 Pahtfinder with 130k miles and a 1998 Rodeo 4×4 with 235k miles).  It’s a 1999 Isuzu Trooper 4×4 with about 190k miles on the clock.  Other than burning oil there really wasn’t anything wrong with it.  Everything worked and to be honest my wife liked driving it much more than her everyday car.  (Read More…)
