Strange one, cupra losing temp whilst driving..

[slim.gt]

Alright guys,

So a few days ago the biza started overheating, so we did the cambelt and waterpump which sorted that out (I couldn't believe it, the propeller wasn't even attached to the spline that spins, needless to say we fitted an uprated metal one) but after driving it a bit today, I have noticed it loses temperature when the AC is on..

I'm not very experienced with this car yet but it sounds a weird one to me, can anyone think of anything?

Thermostat would be my first guess

if the rotor off the waterpump splintered at all it can actually end up sitting in the gap in an open thermostat, so will run constantly open,


as everyones said thermostat, stick a sheet of cardboard infront of the radiator and see if it holds temp... if it does it'll show its a constantly open coolant system

Or just when you are parked up hold the revs around 4-5k and the temps should start to raise. Drive off and the temps will fall again
