The engine was completely rectified; the radiator was maintained and its hoses changed, the cylinder head gasket was tested and cleaned and, when the mechanic assembled everything back, the engine started working better than ever. However, from one moment to the next, the coolant started to be lost and now the mechanic tells me the head gasket needs to be checked once more. I am really disappointed and hope you can tell me what might be happening. My vehicle is a Peugeot 405 gld 95. Thank you very much.
That car will never be completely repaired. I had one as well and, 3000 miles after repairing it, the cylinder head gasket got damaged again, so I replaced it once more, but less than 2000 later, it failed again and for the last time, because I decided to sell the vehicle.
