|Ford focus 1.6 Zetec - Thermostat jumping to red and back again - mcmac74|
I recently put my focus into the garage for a cam belt change at 87K (It is a 51 plate). Whilst the garage were changing it they informed me that the water pump was leaking and duly changed it.
5 days later and I was doing its first decent run after the work and whilst driving on the motorway at 70-80 mph I noticed that the temp gauge was at the max high. I immediately slowed down and looked to pull in at the services. Strangely the gauge dropped to the mid range but then thirty seconds later jumped high again. It did not have this problem before the pump replacement.
The AA did some checks and confirmed it was not leaking. When putting in high revs at a standstill they told me the radiator was remaining cold and the coolant was not circulating.
I have taken it back to the garage and they have spent 3 days with it. At first he said that the coolant was circulating and the next day confirmed it wasn’t. When I spoke to him yesterday he seemed at the end of his tether and was having trouble rectifying the problem.
I have collected it today and he informed me that he has been in touch with ford technicians who could only advise him that some of the dials on the focus are prone to failing? This does not sit right with me. According to the invoice he has changed the Temp sender and thermostat.
I have been given the car back with the advice that the engine is definitely not overheating and that if it was it would be spitting water out and I’d be losing water. The collant level seems stable
I have taken it on the motorway and the problem is recurrent at speed. Once I’ve been at 70 for a few minutes it jumps straight to red (not a gradual climb). It remains in red for a while and then jumps equally quickly down to mid-range. It seems to go make to mid-range more quickly if I drop my speed however it can also drop whilst speed is consistent at 70ish. It is up and down every 2 minutes or so.
He charged me £137 for the latest work which seems to suggest to me that he is acknowledging that the problem still exists but he wants some cash back for parts and some of the labour.
Is the car safe to drive like this? ……and would you cancel the cheque? He is not my regular mechanic and I used him based on a friends recommendation and the fact that he quoted low for the original belt change. He’s a decent enough guy but at the end of the day my car has a problem it did not have before and could potentially cost me a lot more yet.
I'd welcome any replies on what i should be doing next here.
