could be heater hose or freeze plug


possibly a coolant crossover on the engine. With the hood open and the vehicle in park, either have an assistant give it some gas or work the throttle manually yourself and see if you can observe where the leak is coming from.

In 1995 the car stayed the same appearance wise, but the SE and SSE trims received a new naturally aspirated engine, the Series II (RPO: L36). This engine made 205 hp (153 kW) and 230 lbf·ft (310 N·m). The SSEi remained equipped with the Series I SC 3800 (RPO: L67) engine until the 1996 model year, when it too was updated. In March 2008, GM announced that these engines and other GM engines supplied with Dexcool antifreeze coolant might be prone to intake manifold failure and other problems with the cooling system if proper regular maintenance is not correctly performed. After settlement of a class-action lawsuit, GM agreed to compensate owners of many vehicles that suffered damage, regardless of negligence on the part of the consumer, if the consumer can prove damages

Intake manifold problems same as the Regals same engine
