So WP now or....now??? Doesn´t matter if it is doable at home or not, it still needs doing.

Agreed, but we are talking simply about the cause of THIS issue. And the WP
could be it, you may be right. But you are skipping the necessary steps to troubleshoot it properly if you jump right to that. I start simple cause to more complicated. That's just my method and that's all I have been saying.

I know that, but that is not what you told the OP to do so he would have drawn a false and possibly expensive conclusion. If you are going to give instructions on troubleshooting you need to be right, otherwise TBH it is better if you advise to go to a shop, otherwise you´ll have the OP running in troubleshooting circles.

If you paid someone to change the T-belt & the did not change the water pump, find another mechanic ASAP as they 1. Do not know what they are doing. 2. Are not watching out for your best interest. 3. Both of the foregoing.

If you did did the work, you get to go back again.

Good luck with it.

Guys,

the impeller of the WP was broken.

Replaced by the mechanic, now we are doing ok.
