Driving the van I noticed the vehicle started to over heat. I turned it off and waited 1 hour for it to cool down. Started it up again after filling the radiator, with the engine running I made sure the coolant was at the correct level. Within 5 min the car overheated again and this time it died before I could turn it off. I have been told it would be best to replace the engine at 4100.00 for that. I searched the internet and found out there are many other van owners with the same problem. They used a rubber seal without steel so that it coolant leaks into the engine and mixes with the oil, and dries out the camshaft and then it breaks. In canada there is already a class action lawsuit for this reason. They (manufacture) know there is a problem but wont say that it is there fault. I am also looking to find someone to take the case as I currently have a lswn ornament due to I don't have the 4100 to replace the engine.
