Car has been great, always running right on temperature at 190. Then, driving on the interstate 7/29/11, car overheated. I pulled it over and main radiator fan was not running. Took it to my local independent VW shop. We plugged the fan directly into the battery and it did not run. Replaced fan: $275 just for the part! (Unfortunately, the aftermarket fans are, apparently, junk, so this is one thing you should spring for OEM.) This, however, only solved the problem partially: the car was still running hot. (It would idle just fine, right on temp, but under load would overheat.) Turns out these things have a plastic impeller on the water pump! (I would love to know what idiot came up with that idea.) Anyway, had to replace the water pump, too. I don't know which came first, but I'm inclined the think that the pump has not been working right for a while and, therefore, overworked the fan, which eventually failed, and that, when the fan failed and the car overheated, the impeller failure worsened considerably. (The impeller was basically snapped in two!) Headed for the FoodBand tomorrow, as I cannot pay my bills or buy groceries this month. (And, yes, I had to repair the car. What part-time work I have requires it, and I start a new part-to-full time job on the 17th that also requires I have a car. No choice there! - The late charges alone on my other bills will probably add a few hundred dollars to the already almost 1K cost of this fiasco. Many thanks to the IDIOTS who think that putting a piece of plastic around a piece of metal that could easily get hot was a good idea!)
From out of nowhere temperature light came on, stopped coolant looked low, topped up, and verified with another dealer that needed to get to VW ASAP. My husband tried next morning and car died (temperature light did not come on), just ground to a complete hald after 1 mile. According to VW, Water Pump broke that let to this horrific chain of events with an estimate of $2760! for 16 new vales, new valve cover, bla blah blahh... and of course a new water pump and some coolant to go in it. Am pursuing with VW as no way after driving VWs for 20years have I ever had anything like this. Ok water pump broke, get it, 15 other major components.. not acceptable and I am very disappointed.

Car suddenly began overheating, would remain cool upon start for 10 mins or so but then engine temperature would soar.
2004 Volkswagen Jetta- 2.0L 4 Cylinder82,000
Car overheated; temperature warning and check engine warning lights came on. The previous year I had a bad thermostat and thought it might be the same problem. Thermostat was replaced, but there was no heat out of heater and lower coolant hose was cold. Water pump then suspected. When removed, it was confirmed that the impeller was broken in half. In the end - new thermostat, water pump, new coolant, and timing belt replaced (might as well).

My vw is overheating. It won't overheat if I let it idle only when I put a load on it. I replaced the thermostat twice checked the sensors to my fan and when I look into the resivor it seems to be flowing smoothly with coolant idk what else to do please any advice would be great cause I bought it from a dealership around 6 months ago and haven't been able to drive it except home from there

Engine running hot, 260. Replaced Thermostat, Heat Sensor and Radiator. Engine still running hot. Took it to the dealer....they said the propeller in the water pump had seized and needed to be replaced. They recommended to change the timing belt as well...at a total cost of $950.00.

Was passing another car and was really stepping on it and after about 1/2 mile the engine light came on and the temp gauge was pegged! After letting it cool down I restarted and found the radiator fans would not come on, assuming the fan control module went bad I replaced it only to find the same thing everyone else is reporting, it idles with no load in the normal temp range but any load and it overheats. Long story short, I found that the raditor was cold when the water in the engine was very hot and on further examination found that the plastic water pump impeller had come apart......... like someone else said, "What idiot thought that one up!?"
