SHOULD THERE BE A RETURN LINE ON TOP OF RADIATOR RESIVOIR?
1993 Isuzu Amigo • 140,000 miles
I have a problem with my Amigo putting out heat and in Wisconsin in winter this can be a problem with defrosting outside of the fact my Amigo is a soft-top which also creates the nuisance of never getting very warm; especially when the thing isn't putting out heat. I know my thermostat is sticking a little and I will be replacing this shortly. However, the problem lies in the fact that as soon as I turn off the engine, pressure releases and coolant leaves the radiator to the resivoir. The resivoir gets fuller and fuller while the radiator gets emptied and thus, puts out no heat. I have to keep filling the radiator and siphoning the resivoir so the resivoir doesn't overflow. The top cap of the resivoir has a nozzle that a hose could be clamped to, so I was wondering if there should be one there and attached to the engine somewhere so that a vacuum is created and each time the engine runs, it draws from the resivoir to keep the radiator full? If so, where does/should this line run to? This is the XS model, 4WD, 2.6L manual transmission. The coolant system was flushed and cleaned two years ago as well and things are still clean; just thought I'd mention that.
