In a past post a couple of years ago, the details of the Road Runner thermostat housing R&R was discussed. Upon returning from a leisure cruise around town last fall, a small pinhole leak around the weld bead on the thermostat housing appeared. Finally getting around to repairing it in preparation of the annual state vehicle safety inspection and registration process due this weekend, a Mancini thermostat housing was purchased with the hopes that it was sourced from a different and perhaps higher quality Chinese factory than the last one from Moroso. The 160F thermostat was re-used since it was new last time and a fresh mix of Prestone 50/50 was mix used. Only time will tell if this new part will last but along with some engine touch up paint, the darn thing sure looks good!
