Car Forum / GMC Cars / September 2006Is this the dreaded 3.1 head gasket problem
Hi, 2002 Buick Century with 3.1 V6 41000 miles At my last oil change the GM technician reported: "coolant low, has some oily residue in rad. Top up rad and recovery tank and monitor. Likely a rad problem" How likely is this a rad problem? I have extended (Total Plus) warranty. What should I do. Thanks very much. Sounds like the gaskets to me. Just went through this last Dec with my low mileage '01 Grand Am 3.4. I had little pools of coolant visible also on top of the transmission where it attaches to the engine. > Hi, > 2002 Buick Century with 3.1 V6 [quoted text clipped - 8 lines] > What should I do. > Thanks very much. > Hi, > 2002 Buick Century with 3.1 V6 [quoted text clipped - 5 lines] > > How likely is this a rad problem? It's likely that there are multiple problems. Possible transmission cooler leak in radiator. Possible coolant leak at intake manifold gaskets. Possible head gasket leak. > I have extended (Total Plus) warranty. > What should I do. Have it checked more thoroughly. Read your warranty provisions. > Thanks very much. > Hi, > 2002 Buick Century with 3.1 V6 [quoted text clipped - 8 lines] > What should I do. > Thanks very much. Where would oil come from found in the radiator, except the engine? Leaking gasket would be a good bet. > > Hi, > > 2002 Buick Century with 3.1 V6 [quoted text clipped - 10 lines] > > Where would oil come from found in the radiator, except the engine?

Like Aarcuda says, you need to rule out the tranny cooler core in the radiator. If you get coolant back into the transmission (leaks are two ways, usually) and you will soon buy an tranny overhaul. It may well be gaskets, but you need to be sure. Could very well be transmission fluid in the tank. The rad could be bad . Fluid could be leaking into th rad . Check transmission fluid and oil levels. I bet it is the rad. >Hi, >2002 Buick Century with 3.1 V6 [quoted text clipped - 8 lines] >What should I do. >Thanks very much. > Could very well be transmission fluid in the tank.

Considering the very high failure rate of intake manifold gaskets on those engines I wonder why you suspect the radiator first? John All answers you get here are pure speculation. Get it to the dealer and have it diagnosed correctly. > Hi, > 2002 Buick Century with 3.1 V6 [quoted text clipped - 8 lines] > What should I do. > Thanks very much. > All answers you get here are pure speculation. Get it to the dealer and have > it diagnosed correctly. Dealers a.s, dude... You are showing your innocence. If 'dealer' is the only word in your vocabulary, your are on the wrong newsgroup. But when you say 'have it diagnosed correctly', you have partially regained some credibility. Obviously you have the greater credibility. Why in the world would one want to take their $30,000 vehicle to a place that has all of the special tools, equipment, as well as factory trained technicians who have instant online access the manufactures engineering department to be diagnosed and repaired, when he can take it to a guy with an adjustable wrench, dwell meter, vacuum gauge and a generic manual that he got free when he completed two semesters at DeVry ten years ago?

I wouldnt have seen My c.nts post normally, since I killfiled him long ago. A problem like the one you describe doesn''t require a dealership, nor even a ton of high tech equipment. Many of us here have such sour tastes in our mouth because of GM treatment and dealership mechanical practices that your post, at least in my mind, immediately indicated one of two things...either you are of My's mentality, or you are a newbie. Dealerships often SUCK. Maybe even usually SUCK. You find a good, honest, competent mechanic and you support him. I find good independents are usually far preferable to the dealership spunkmonkies, and often are cheaper as well. In general, they appreciate your business, and try to do a good job. > Well spoken.... Really? I count at least 6 inaccuracies/exaggerations in his post. > Obviously you have the greater credibility.

Does mommy know you're playing on her computer ? From this and at least one other response , you seem to be about 10 yrs old ... Damn straight I'm a biker , what of it ?

You could very easily have the infamous leaking intake manifold gasket. Oily residue in the radiator can not be caused by a radiator problem. John > You could very easily have the infamous leaking intake manifold > gasket. Oily residue in the radiator can not be caused by a radiator > problem. Why would you say that? I've never seen "one" leaking intake manifold gasket on these engines contaminate the radiator with oil, but I've seen "tons" of transmission coolers within the radiator leak and cause oil contamination of the coolant.
