Recently my temp guage hasn't always been getting up to or staying at 90°

 

From what I gather the thermostat might be on the way out as its possibly sticking.

 

I've tried searching but cant find where exactly is it on a vRS (ASZ)?

 

A photo would be great 👍

 

Thanks in advance

 

 

Its behind the vacuum reservoir, (the black plastic ball on the front of the block held by one hex bolt) I would also replace the thermostat housing as the little plastic tags get brittle and fall off and usually end up stuck in the thermostat....sticking it open!!

I was thinking of replacing the housing too from other posts. Thanks for the info. I was thinking I was going mad when I looked & couldn't see it.
