I need to remove the thermostat in my 1993 SL1 to flush out mayonnaise-like gunk caused by a blown head gasket; oil mixed with the coolant. I pulled the elbow that covers the thermostat, but found that the thermostat is built into it and held in place by a strong spring that I couldn't get any tool on.
Anyone know an easy way to extract the thermostat?
Thanks,
Gary
