Well I too had a similar problem with my minivan unfortunately if its not a hose leak then most likely you will have a gasket leak it is a typical problem with these cars I paid 1000 to get mine fixed a couple of years ago. There is a lawsuit going on with dexcool and General motors here is some info on it if you do have to repair it.I'm currently registered with these people on this lawsuit you can contact them at the number below. Hope this helps
We are pleased to inform you that we have reached a tentative nationwide settlement with General Motors.
You will have the option to be included in the settlement if you incurred out-of-pocket expenses for any of the following repairs: 1. A replacement of the nylon/silicone lower intake manifold gasket, made within 7 years or 150,000 miles of the date of initial delivery for 1995-2003.5 Model Year vehicles with 3.1-liter V6 and 3.4-liter V6 engines, where the vehicle was originally equipped with Dex-Cool coolant.
2. A coolant sealability repair (including, but not limited to, throttle body gasket, upper intake manifold gasket, lower intake manifold gasket, etc.), Made within 7 years or 150,000 miles of the date of initial delivery for 1995 - 2004 model year 3.8-liter V6 engines (RPO L36), where the vehicle was originally equipped with Dex-Cool coolant.
3. A Dex-Cool sludge repair, made within 7 years or 150,000 miles for 1995 - 2000 model year S/T light trucks and sport utility vehicles with 4.3-liter V6 engines and originally equipped with Dex-Cool coolant.
The settlement will require you to provide proof that you owned or leased the vehicle at the time of the repair and that you paid for one of the repairs described above. If you do not have a receipt, ask the auto repair shop that did the work to provide you with one.
The terms of the proposed settlement are confidential while we work to finalize the settlement papers for court approval. If the court preliminarily approves the settlement, the parties will publish, mail, and email a notice that describes the terms of the settlement and your legal rights. We hope to obtain court approval and get the notice out by February. At that time, we will be able to answer inquiries regarding the specifics of the settlement and how to file a claim. In the meantime, you should retain all receipts you have for repairs to your vehicle's cooling system. Also, if your mailing address, or your email address changes, please notify us by email.
