Re: AIRLOCK causing coolant to shoot out of Radiator Cap?
It happened to us once, a long time ago.
The coolant would get spilled all over the place when after driving for some time; you could even listen to it burping and bubbling in the reservoir. It even lead to overheating and we had to rebuild the engine for a second time. MAKE SURE the water pump is OK I don't know in your model, but in mine the impeller was all rotted and wouldn't operate properly.
What we did to get rid of it was to bring the engine to normal operating temperature, turn the heater to the MAX setting and rev the engine to 2k RPM's for 30 seconds, ask an assistant to do it while you take a look at the reservoir. DON'T let it run out of coolant, top it as necessary. Let it idle for 30 seconds and repeat until the coolant level is steady in the reservoir.
Oscar.
