hello again

the pump is very important thing

have they installed thermostat correctly???

there are no miracles in the technic -- so somewhere is a problem:

- air inside;

- coolant pump;

- radiator blocking;

- thermostat failure;

- head gasket was tighten incorrectly;

You'd start to investigate.

Good luck/igor

the idea is to measure the max coolant themp -- so it might be on the outlet pipe from cyl head or oon the cyl head -- just to locate it.
