Crazy issue heat gauge going up and down while turningDear all i am facing this problem since a week
It all started when the first time my heat gauge raised just a little after the 3rd line wich my car never did as i owned it for the last 3 years ago and today while going to work i released that when turning right and left the heat gauge turns to up and down as i already changed the coolant and have made a full flush and it seems to run pretty well i would like to know is there a way i can fix it my self so it will start working again i love my ls400 2000 model so badly

When you refilled the engine with coolant, you left a large air pocket in the top of the engine. Need to use the right process and the correct filling port to eliminate this issue. Search in this forum.
