Renault Laguna 2.2 dt - john wilson
Owned from new a '96 hatchback & now vhm.Have recently had the engine cooling water thermostat changed at franchised dealer. It has been serviced at correct intervals. It now provides a highly variable and varying reading on the dash temperature guage when 'warmed up'. Any advice or experience would be appreciated, please.

John,
a bad connection from the temp guage sender would or could cause such symptoms, by varying the resistance. I've no experience with the laguna as such, but they are usually close to the thermostat housing, and it may well have been disturbed. If you have just had the thermostat replaced, then presumably you had temperature problems previously, which have not been totally cured. Also airlocks can cause similar problems.
Regards
Mike

Could new thermostat be sticking?

Is your cambelt OK? I recall from earlier posts that the belt on this engine was rather weak?
Check for airlocks, these would cause the symptoms you describe.
Many workshops neglect the importance of bleeding the cooling system properly and wonder why they find themselves doing the job again :-(
