They recommend 5w30 weight oil, witch I like running in the cold weather, in the heat I like 10w30 weight. Also keep with the dex coolant. That is what it came from the factory.

On a cold engine that could be normal. My '03 S- 10 Pick Up with 286,000 miles on it sometimes does that, especially in the winter. Then once it warms up the gauge dropps back to normal. When flushing the cooling system just use plain water. No chemical cleaners unless it's running hot or overheating. On an older model something's bound to spring a leak if you use a chemical cleaner.

Better to read high than low. I agree with Js08016, if it drops back to normal after the engine gets up to temp - leave it be. Good idea to drain and change oil and see what happens to it with proper viscosity and fill level.

Have a 2000 SSEi with 199k. Have used Mobile1 synthetic since day one. 5w30 year round. Engine is like new, inside. Never too late to start, eh?
