| My STS is a 98 model and when accelerating, a sound of water or some other liquid is heard from above the footwell on the passenger side. Any ideas of what it is and how it can be eliminated? | |
I have a 96 STS with 135K mile. There a a lot of rattling at low speeds from the front end over moderate bumps in the road. Does anyone have any ideas what might be the cause: worn out bushing, grommets, or shocks? Or all the above.

Hello all. I am brand new to this forum, so I hope I'm posting this in the correct area. I am in the process of buying a '96 STS from my inlaws. The car looks perfect and, when running, runs perfect as well. About 6 months ago, the car began having problems that, when it would sit for a couple days, the battery would run down and the car would need to be jump-started. Since the car never really sat for more than a couple days, it wasn't that inconvienient. The past 2 weeks, however, (since I have aquired the car) the problem has increased. My wife can drive it for 45 minutes, go inside a store, come out 15 minutes later and the battery is dead. A mechanic said he went over the car with a fine tooth comb and can't figure out what's causing this problem. If there is any advise or ideas of what this problem might be, PLEASE, post up and let me know. For the price I'm getting this car for, it is well worth dropping money into to get it fixed and I'm willing to do that. Thanks for your time!

| i have a 90 sts that is in A-1 condtion. I'm having a bugger of a time with the climate control system though. It seems that the blower works fine when in AC mode but will not blow in heat mode. To make matters worse the hot air does not stay hot. As you drive it the air goes from hot to barely warm. I live in Wisconsin so this gets to be a mite chilly. I have had the car for 7 years now and this problem just started occuring. First with the blower and now with the heat. Anybody have any suggestions???? | |
| Many thanks to all of you who have repeatedly posted your comments on the well known issue of Northstar head bolts losing thread integrity in the block leading to head gasket issues. I own a 1998 Seville STS with 194,000 miles. The car is in excellent condition except...... at sustained highway speeds the coolant is forced out of the coolant tank cap. The car will overheat when the level drops enough to stop flowing or gets "air bound". This car is in good enough condition to drive everyday, runs great, but cannot be driven at sustained speeds over 60 mph. Its age and condition does not warrant installing a long block or a major teardown on such a high mileage engine, the cost alone would be more than the car is worth. For those of you in my situation I have engineered a less than perfect but workable solution. My thinking was how to vent the exhaust gas and pressure to prevent forcing out the coolant. Being a Chemical Engineer I'm very familiar with industrial hot water systems. Many of these systems cannot tolerate air in the piping. Most of them have air vents in the piping system. They are high pressure and high temperature. I have installed a 1/2" NPT float type air vent into one of the cooling system bypass hoses that now vents the trapped combustion gases. The vent is rated at 50 PSI and 250'F. It has worked for over 1000 miles in the last month. It does not pass liquid, only air. Today I drove home on the Interstate at 70MPH for over 40 miles with an outside temperature over 80 degrees. No overheating. I will post a picture if there is any interest. Good luck. | |
