110 V8radiator cap and overheating?

I've noticed recently that my 110 is running at a slightly higher temp. Not overheating as such, just the wrong side of the centre line on the gauge (used to always run just below the centre). I put it down to the hot weather, but it's cooler now and about the same position. Last night I happened to open the bonnet after a short run (to normal temp) and noticed the expansion tank cap was gently hissing. If the cap was operating/venting below pressure, causing the cooling system to not be pressurised correctly, would this cause a slightly hotter running system?

If the cap was

Hi Danny

YES - I'm not going to go intat physics of it, but get yourself a new one and the temperature should drop.

a higher pressure cap will allow a higher boiling temp .

check you have the right level of water in the system , it may have lowered the water level due to steam/water escaping rom the expanded system and thats why you have higher temp on guage.

a petrol engine will be very likely to overheat in this weather anyway , diesels allways run cooler .

hope you still have the fan cowling behind the radiator and havent removed it like many do , because this will make it run hotter.

check youre ignition timing also , that it hasnt moved. prob set at TDC or 6deg ATDC on 110 v-8 ..

I'm a little aware of the physics, since my business is espresso machines (big old lever machines) where the boilers are kept pressurised, with the resulting increase in water temp etc...
