Hey, Rodbolt, (or anyone else), can you give more details on how and where to cut the vent in the OMC thermostats?<br /><br />I read the comments earlier on this thread about stats sticking, but can't get Sierra stats over here, so I've bought an OMC one. Before I fit it, from what Rodbolts says, I ought to cut a vent in it somewhere to stop it from sticking. I don't have a clue where or how, a diagram would be good <br /><br />Thanks<br />Steve

The reason they stick is because the thermostat cavity does not drain if the tiny bleed hole gets plugged up. Not only that, but a plugged bleed hole causes an air lock and the cooling water cannot reach the thermostat elements and the motor overheats.<br /><br />An easier way than drilling the thermostats is to file 2 small notches in each white plastic pressure relief valve, one at 12 o'clock and one at 6 o'clock. Use a small triangular file. That way there are both bleed holes and drain holes in the housing, and the thermostats won't stick.<br /><br />Another way to eliminate drilling the t'stats is to use a duck-bill pliers and carefully bend the valve flange slightly to allow air to escape. Don't overdo it or the motor won't warm up enough at idle.
