ENGINE OVERHEATING

My van just started to overheat. I checked fluid level and it is full. With heater running on full, it runs cooler when I sitting still than when I am moving. Any ideas?

My sedona drives with no problem commuting locally, however the heating takes long to heat up.

But when driven on the motorway for longer journeys, it heats up and stops accelerating for certain intervals, then I have to pull over to allow to cool before driving again?

Please help!

iv'e found what appears to be oil in my coolant tank but not sure can someone please help

If there is oil in your radiator that indicates a big problem. If the oil only appears to be in the overflow tank then was the cap on did you spill some in there or is it road grime?

A crack in the head gasket or less commonly the engine block will allow oil to pass to the cooling system. Check you oil level to see if excessive oil has disappeared. Try and get some of the coolent out of the tank for a better view. It always looks dark in the radiator. There is usually some oily veins that appear darker on close inspection. If your engine is running the oil may produce dark bubbles in your radiator during turbulence.

Good luck. If you think it's still oil, get someone else to look at it.

Conversley - check your oil for radiator fluid on the dip stick. Always a good idea to change the oil to be safe.
