Yer open the expansion tank cap and see if the water being pumped back in to the tank with a few revs on and it may be a faulty thermostat even after a year

[opel]

It a rubber seal u may get it with the stat.. But if you get it from vow I think you have to buy on might be wrong on that tho

replaced stat today what a pig got there in the end. temp comes up to 90 now after a short run 
the bottom hose seems to stay cold for a very long time and the top hose red hot is this normal
after a  good while the bottom hose gets just as hot is this because the stat has opened ?? hope so
