After driving the car for a couple of hours today, I discovered the cracks are back and looks like the tank is about to start leaking bad. I also notice the upper radiator hose is "inflated" when the engine is hot. Both tank and hose are 6 months old. The car is NOT overheating and I have tried with 2 different pressure caps (one MB original and the other one "Germany" branded, both rated to 1.4 bar).
Things I haved replaced in the cooling system during the last year: water pump, all hoses, thermostat, radiator, expansion tank, expansion tank cap, coolant. Fan clutch and aux fans are working normally. Car temperature is also normal.
I'd like to belive it is just a bad tank.....
Any aditional comments will be greatly appreciated.
P.S. Thank God Boing engines are made by Rolls Royce.... 
Thanks. |
After viewing the photos of your hoses, I believe your problem is a bad head gasket. I just went through the same problem last week. I replaced my head gasket because oil got in the coolant and head pressure blew out the bypass hose. Not a fun job, but it had to be done. I also replaced all of the rubber hoses due to oil contamination and swelling.
