Volkswagen Jetta Problem Report
Volkswagen Jetta Engine Overheating Due to Damaged Water Pump Impeller
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!) - Visitor
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. - Visitor
Car overheated, replaced water pump, and thermostat - Visitor
damaged water pump and need a new head gasget, transmition is skipping and take off is bad. - Visitor
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). - Visitor
water pump impeller broke , engine over heated with no heat from heater and lower radiator hose was cold. new water pump installed with metal impeller and new coolant and new timing belt kit . - Visitor
water pump impeller stripped out because it was plastic. car would over heat in 5 min or less. change pump car worked fine - Visitor
Water pump leaking coolant, causes engine to over heat - Visitor
Car suddenly began overheating, would remain cool upon start for 10 mins or so but then engine temperature would soar. - Visitor
Overheating engine. Half the pipes were hot, half were cool to the touch. Radiator was cool to touch while engine was overheating. - Visitor
Overheating. ..hadd to change coolant sensor temp - Kaylleena1
indicator lights says hot. 220 degrees. the thermostat hose blew off... I put it back on and drove it home pulling over ever 3 miles to let it cool for 5 min. I got it home without cracking head.. have had a lot of problems first radiator, thermostat.3 sensor heat fuses for fan. now what I think has to be H20 pump. wonderful car till have problems no such thing as nickel and dimes 100"s of dollars,, - baysmom
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!?" - Visitor
Over heated. Have to change water pump , thermostat, and timing belt for about 900$. - Visitor
replace water pump - impellor separated from pump - Visitor
Plastic propeller broke into pieces at 80k........had to have top end rebuilt.... - Visitor
engine overheated out of the blue. turned out to be thos very same problem. Rod East wv repired it 1200.00.very surprised with this low milage. - Visitor
Pump failed at 88,000. Replaced no issues up to 105,000 miles. - Visitor
It began overheating so we let it cool and put water in it but the water just kept coming out - jette95
Engine was getting hot at stoplights during the summer. Otherwise was running fine. Dealership mechanics replaced the waterpump for a little more than $900. Problem returned a few months later. I personally looked into the problem and researched online. Found that the thermostat housing was a common failure item. Sure enough, ours had failed. Upon removing it, the internal walls of the plastic housing were crumbling and leaking coolant onto the engine block. Replaced the housing, "crack pipe", seals, temp sensor and thermostat - parts cost was about $200 but the labor was killer - the "crack pipe" is located on the front of the engine and is particularly hard to reach. - wcraft
The fan is working and I've had no leaks from the water pump. My friend thinks its the thermost...
dealer ship is claiming a plastic should be used being a metal if broken will destroy an engine...
engine check light is stuck on need engine code.
My 1997 VW Jetta is constantly running on the verge of overheating near the 230 mark on thermos...
