1988-1998 GMT400 (CK1500) GEN 1 Coolant Overflow Reservoir (Polished)

This is the last of the Gen 1 reservoirs that we had in our inventory. This reservoir still has the original width dimension, before we slimmed them down to accommodate for the earlier model AC accumulators. If your AC accumulator has a horseshoe shaped line coming straight out, this reservoir will not fit. 

This reservoir has the baffled overflow fitting and a non-vented cap. We have since eliminated the overflow fitting and replaced with a vented cap. It is fabricated from .100" 5052 aluminum - we have now gone to .125" 5052. The welds on this reservoir are not our absolute best - probably why it is the last one in our inventory. 

It has been pressure tested and is fully functional. 3/8" Barb fitting for the coolant connection. Sight glass included. For someone looking for a more inexpensive polished reservoir, this is perfect for you.
