Worth checking injector wiring harness too.
as in just normal driving temp. not overheating i do find it looses i little coolant over a few weeks. as in say half inch in bottle if that,how hot is it getting? hot as in roasting? thermostat??
If it's not getting too hot - as in cooking (overheating).
Try a dose of injector cleaner as a first fix - cheapest fix to try after changing filters.
May take while to show any improvement - if there is none - could be reduced fuel pressure (pump) or injectors. Getting expensive ££££
Give it a good dose of cleaner and see what happens - if it improves you're on the right track.
