1998 Chevy Blazer S10
Have had coolant leaking from drivers side at back. First, changed themostat. Then water pump. Flushed through rad. All fine for awhile with small leaks. Then one day overheated to point of "Check gauges" coming on. Was going to pull over but temp gauge dropped within seconds back down to normal? Changed thermostat again. Since then, sometimes have no heat, then it comes on as normal-overheating has happened twice since this and once and awhile coolant will literally pour out until all gone. We have tried and tried to identify exactly where this leak is coming from but it seems to pool down and we cannot find the leak. Could it be the freeze plug, intake, please help. Oh, one other thing-sometimes the coolant reservoir is still full but rad has lost some. Also, where could we get the service manual for the coolant system on this model? Thanks in advance for your help and info.
