So I have been talking about a full coolant flush and hose change on my clio 182 for a while now. Decided I’m going to gather all the necessary parts then crack on with the job. Thought I’d buy a new thermostat and housing gasket to tick another thing off the list. However RPD want £36 for the genuine Renault thermostat. I can buy a pattern variant from ECP for about £8! So are the ECP versions complete junk? I would prefer a OE version but that sounds prohibitively expensive for a thermostat! Any thought? Is it a case of buy cheap, buy twice with the ECP version?
