The only difference from the 11811 is exchanger position — rear vs. front. When advising customers: if their engine room plumbing exits from the rear of the tank location, the 11812 is the correct pick; if from the front, the 11811. Unit cost is nearly identical to the 11811 ($567.06 vs. $554.12) — no meaningful price reason to choose one over the other; installation layout is the deciding factor. Engine coolant-only restriction applies equally. Weight is recorded as 0g — missing data, obtain from Kuuma spec sheet and update (expect ~8.8–9.1 kg based on sibling units).
