I purchased a replacement thermostat last week for my E270 CDi 2003. It was from Euro Car Parts so I wasn't looking for ultra cheap Chinese item. When I went to fit it yesterday I was surprised to discover that the replacement stat DID NOT have the same fitting holes as the Mercedes item. If you look at photo the hole on the top was there ... but not threaded. On original item this takes a bolt that holds a small clamp for the two fuel pipes. The other hole arrowed (no hole on the new part) was for a fixing bolt on the original part. I assumed I had got a duff part where the machining had been missed. I took part back .... surprise, surprise all were like this. Looked at parts from two brands, Circoli and Gates, neither of them had these two threaded holes. I was just surprised that a supposed 'pattern part' can be produced without the same fittings. The hole on top is important ... as it takes a clamp that secures fuel lines. Has anyone else had the same issue. I'm not keen on buying these 'commodity' items from Mercedes as they charge ridiculous mark-ups and are usually made by same manufacturer that supply Mercedes, however in this instance it would appear this is not the case.
