As soon as I turn the key on the temp goes to hot the Car is cold after starting the oil will go to high, I have changed the temp unit but still the same any idea what is doing this, I was thinking about a new dash cluster.

See if the wires leading to sensor are getting power or not if they are then it's probably the dash unit.

I agree with HMAC300, the cluster sounds like it is bad which is common, here is how to remove the cluster so you can get one from ebay used, which is cheap. Check out the images (below). Let us know if you need anything else.
