HeavyHaulinMac Posted January 1, 2018 Share Posted January 1, 2018 I have an 02 Mack RD and this cold weather is staying for a while. Never plugged it in since it was new... Never had a problem with it starting and still don't, maybe she takes one more stoke at 10 degrees as opposed to 40. Just wondering if there is a way to make sure the block heater is still good and not have a cook wires/ have a fire. Should I even consider starting plugging it in at all? Once she kicks it might miss on one or two cylinders for like 5/10 seconds but then smooth as glass.

blackdog2 Posted January 1, 2018 Share Posted January 1, 2018 It dose not hurt easy on everything and less antifreeze leaks better than either and staters and you get heat right away .

hatcity Posted January 1, 2018 Share Posted January 1, 2018 your oil will be more to its designed viscosity when heated. Flows quicker to the internals. if you do plug it in, turn the heater control to defrost. will have warmer air going to windshield Quote Success is only a stones throw away.................................................................for a Palestinian Link to comment https://www.bigmacktrucks.com/topic/52093-e7-block-heater-test/#findComment-388726 Share on other sites More sharing options...
