2000 volkswagon tdi rose above the 190 temp. last night coming home. Gauge went approx210 and then back down. Car has 127.000 miles.Timing belt water pump etc. changed at 90.000 Thanks

hmm try to check all bolt and pipes

My experience with the chevy coolant system, cambelt/timing belt will probably not affect the temp. Never-mind what pseudo half wit wanna be mechanics tell you, trust me, they just want your money for work that doesn't need to be done. Start with getting a repair manual for your car, Clymer, et cetera, can be purchased in any Pep Boys, Advance Auto. First check for leaks, especially around timing belt area, which will mean faulty water pump, then and only then do you replace timing belt and water pump. If no noticeable leaking, check level. If that's fine, make sure anti freeze is appropriate mixture strength, lastly replace thermostat. Auto repair manual will tell you exactly what tools are required and level of difficulty in replacing thermostat. Fairly easy, but I have been doing it since birth. One more thing, if your car is within operational temperature standards, don't sweat it, it's an old car and they get weird with age!!!! Hope this helps! If problem persists after this, contact me personally!! Thank you!

well it sounds like your thothle could be sticking need to clean it with caborator cleaner or check your idle with timing light to see hows your timing is....

It sounds like the water pump shaft bearing has frozen up. A hint here, always replace the idler pulley and water pump when you do the belt, they make kits for this and they have all the parts that wear out along with the belt. As long as the engine doesn't get to hot you should be ok.

It sounds like your water pump is shot. The small antifreeze leak is the coolant probably coming from the weep hole on the water pump. If you ran the car while the temperature was up, you may have to watch the head gaskets from now on as they may be shot. Water pumps wear out around 100k to 150k miles usually.

Probably a cooling fan issue or maybe a stuck thermostat.. change thermostat and check that cooling fans engage..good luck...also when you fill up the resorvoir let it be for a while and check to see if level is down, sometimes it takes a while for water to seep into radiator, i assume you dont have a radiator cap?

Its a bad temp sensor.good call!

Sounds like water pump or your thermostat the second is cheaper

they set the timing WRONG and that is an interference motor so the valves hit the pistons

Hi Kevin,
I hope it stays fixed. If it does, I'd appreciate a rating when you have the time. Cheers, D.
