The "90wt"
may be stop-leak gelling. Are you having any cooling system concerns?
No heat and/or engine overheating?
First, inspect for any evidence of previous leakage. Check the condition of the hoses.
You will likely need to replace the thermostat and flush the entire cooling system and retest for leaks. Pay particular attention to areas like the water pump, intake manifold etc.
I hope this helps.
