Well been having issues with my car not getting up to temperature. I had changed the coolant temp sensor and thermostat last year for peace of mind and all has been fine until a month ago.
Finally decided to have a look, so got the coolant temp sensor changed for a new one under warranty which made the dash gauge a bit more responsive but still had issue.
In the end I decided to change the thermostat as it could have fail in an open state.......on inspection I discovered a random plastic peg wedged in the thermostat keeping it open and the cause of all my probs as when that was out and stytem filled again, the engine got to temp in no time at all.
Here is the item so please throw me any ideas to what it could be?
