Passat overheating problem

Hoping someone can help here, i have a 51 plate passat 130TDI. when driving it generally is ok but when i put some strain on the engine by accelerating the temp gauge shoots up, i have renewed the fan and bearings also the thermostat, but the problem still persists.

Any ideas.

change your water pump. many miles are on it??

140,000 miles, ....surely if it was the water pump, would it not be overheating all the time...?

possibly not. at higher rev's your putting it under more pressure. when was the last big service done?? as in the water pump and timing belt done?

Timing belt done at 120,000......water pump never been changed....

140,000 miles is alot on one water pump.

WOW should have done that when T-Belt was done.
The Water pump has plastic impeller that over time brakes in such a way. That does not show over heat at lower speeds. But when temp rises or higher engine speeds then she shows her ugly face.
When you have it change replace the pump with a metal impeller they cost the same price.
