Red face ZS 180 Temp issues

Hi all,

recently bought a ZS180. The car was great on the journey home, but a split coolant pipe meant it went to the garage for a while. However, the temp gauge goes above half way, more towards 3/4 mark after about 20 minutes running. It goes back to normal if I put the heater on though. Ive spoken to a few owners and it seems to point towards a thermostat issue. Im willing to get it fixed, however I don't trust my local garage. I was charged 300 to fit an 18 pipe as they couldn't locate the issue at first. I took it back but they claim its running fine, more like they aren't interested, they just said it might be HG....on a V6.
Its not loosing coolant, so I don't think its anything major. Just after a second opinion and if anyone can recommend a MG specialist near Kettering, Northants.

Not an expert, but sounds like it is either the thermostat or air in the system. I thought there was a certain way to fill the system, which involved using the plastic bleed screw in one of the coolant pipes (next to the block, just below and forward from the throttle body) - maybe the garage you used have not bled it properly after refilling? Might be worth finding the filling procedure, and draining the system and refilling it properly. Wouldn't take long to do.
With regards Mg specialists, sorry, don't know of any personally in the area. When I had my belts and water pump changed, I had the guy from Derby come down (just outside of Kettering). MG Rover Mobile Specialists or something like that. Another possible is a guy over in Olney. Phil-T4 on the forums. Although a small job, he did my key fobs a few years ago, and was saying he does work on Kv6's although at the time was more ZT, I think. Might be worth a call? Also called MGR T4 Services.

I would say air in system if thermostat was working ok before, when I used to do coolant change on my V6 as mention above there is a plastic bleed screw in the hose next to block. It's very simple to refill system on these engines I never had an issue. I did it a second time when I changed the thermostat, housing and plastic pip on top of block which is another common fail,point.
Your garage doesn't seem upto the job and I would take action if you manage to sort it your self.
