NL | Hello, here is some absolutely enthusiastic and long overdue feedback: On July 13, 2021, I ordered two Steel Seal cylinder head gasket fixes from you (invoice no. 20211149). It was a purchase out of necessity, as our motorhome (Renault Master 2 base, dCi 140) increasingly - but not always - showed white smoke in the first few minutes after a cold start. I also noticed a corresponding loss of coolant. Replacing the EGR valve, which I had been advised to do, was unsuccessful. I wanted to be prepared in case the fault got worse during a tour and at least have the chance of a manageable repair. In the summer of 2022, the time had come: the car smoked considerably in the middle of France. I stopped the vehicle and remembered the two Steel Seal bottles. I let the engine cool down for 24 hours and meticulously followed the instructions in your manual. The repair has been a complete success to date. The vacation (and all others so far) was saved. Huge praise for your product! Hilmar Steppat 30.04.2024, 30659 Hanover |
