Getting ready to install new reman water pump. Measured the grooves and appears I have the one with the 4.5 mm gap. So I will be installing the 2.5 mm thermostat seal and snap ring only (the seal under the t-stat in pic below). I'll disregard the 4.5 mm seal and spacer shown the pic.
Please verify this is correct. I took a pic of the measurement. Had to try to line it out on a piece of hard stock then measure with ruler.
Thanks.
