Checking Engine Oil It's a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. 3400 (Code E) V6 Engine 3400 (Code E) V6 Engine 3800 (Code K) Engine The engine oil dipstick handle is the yellow loop located near the front of the engine. See Engine Compartment Overview on page 5-72 for more information on location. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level. 3800 (Code K) V6 Engine 5-16
