Question about Cars & Trucks
Let the engine cool down then remove the radiator cap. With the cap off, start the engine and let it idle. Watch the water in the radiator. As the engine heats up, the water will rise as it expands during heating. When the thermostat opens, (and this may be your problem) the level will drop, and you will be able to see the water recirculating through the radiator. If this doesn't happen, the thermostat is not opening (stuck closed). If you can see the water recirculating when you start the cold engine, then the thermostat is stuck open. Either condition will cause overheating. Start with the easy fix first (thermostat) before going to the water pump.

Don't mind helping but there are several pictures as well as written instructions. To much to cut, paste and all that stuff on fixya plus there is a size limit on pictures as well. If you want, email me directly at email@example.com with your vehicle information (year, make, model) and I will be happy to make up a PDF and email it to you with pretty detailed instructions and pictures. It won't cost you anything but will need to know if the 8th digit of your VIN is a S, 2 or a U so I'm sure I give you the right information.
