Good afternoon all,
Last week my 1997 BMW 540i may have finally quit on me. After 2-3 weeks of a fluctuating thermostat. The radiator simply "popped", emitting a steam cloud and some coolant/water.
Now, hours before the 'pop' (at least 2 hrs prior) I put water into the reservoir which I noticed was bubbling unusually and excessively. I have owned this vehicle for 6 months now and NEVER experienced such a problem.
I am afraid I may have an underlying head gasket issue (cracked or blown), something I cannot afford to fix in this or the next lifetime.
The car still turns on as normal, also driving as such. Now, I am aware NOT to drive it, for the risk of burning it out completely.
However, my question is: Should I replace the radiator for now and work my way up to the gaskets? Or am I wasting my time buying the radiator? OR is it possible to solder the cracked area?
I must add, I questioned why the thermostat went up and down, even while driving; my car showed no signs of overheating. Therefore, many told me that the thermostat may be broken and I would simply need to replace it. All in all Ididn't think much of this.
What do I do!??!?!? I'm nervous that if I buy a new radiator that I might be wasting my money
