Recently installed a circulating coolant heater in my 2000 Dodge Ram w/3.9 litre. I installed it between the block drain and the heater hose (as per instructions). When I power it up though, it very quickly boils my coolant but doesn't really heat up the engine. I've left it on for 4 hours before and other than hearing all the air in the heater core, it didn't appear to do a whole lot. I double checked the flow coming from the bottom of the block, and I positioned the heater as low as practical (well.. the only place I could really put it which is just above the idler arm on the frame) The heater in question is a 1000 watt Temro Industries heater. If anyone has any ideas about this, it would be greatly appreciated.

Re: 1000watts. If you check the zerostart catalogue, which I did originally, this is the one they call for with this application. I don't know why, but it is. And since it wasn't cheap, I don't think taking back off is a good idea.

As for the thermostat points.. it's not supposed to heat up the rad.. just heat up the coolant in the engine.. and yeah.. it's on a timer set to 4:30am and I leave at 7:30

Okay, I got an 800, as soon as the weather calms down, I'll try it and let y'all know how it went.

im sure your problem is in the circulation route of the heated antifreeze - remember the heater valve will probably be closed when there is no engine vacuum so there will be no place for the warm antifreeze to go . and 1000 watts is NOT too big for a 3 hour warm up. - ( coolant takes a lot of energy to warm )

My thinking is that there is no way it's heating the coolant up by the thermostat enough to open it and allow the circulation, it's just warming the coolant in the area. I personally use a 400W heater that threads into my block drain, on a timer to come on 4 hours in advance and warms engine enough that the car starts and immediately goes into low idle in the coldest days (-15 to-25C) and the gauge is at full operating temperature within a few minutes of driving

coolant boils at an noticeably intense temp water boils at a decrease temp coolant is meant to be a 50/50 mixture of coolant and water your difficulty is that you've too a lot water, which lowers the boiling temp. the clarification your automobile isn't overheating is because the air that passes through the engine (via the grill) is cooling it down adequate. do comprehend that idleing will make you automobile overheat. what you pick to do is superb off you coolant with organic coolant to make it in the route of a 50 50 ratio. also the coolant boils after time because each and each and every time passes via the engine it get hotter. the steam is the in common words ingredient that seems off. you should have a small guage through your speedometer, even as this occurs, ensure it does no longer get on the point of the H. if it does close off your automobile asap (some seconds is all you've). yet you pick to operate the organic coolant also, which will restore it.

I prefer to go with the freeze plug installed block heater. It will give you instant heat and it seems to be more reliable. You cannot rely on the circulating type for two reasons: the engine thermostat will impede flow and will not open until 195 degrees so your heater will never open it, and 2) if you forget to set your heat controls to "full heat" then it wont be able to circulate thru that area either.
Good Luck!

i own a repair shop,and that's too much for that one ,the one you bought would heat a large diesel engine,you need a smaller one on it like a 750 or less ,it supposed to help heat everything up on it not just boil it like that ,that means its heating it too fast,try a smaller one,i think you will get better results from a much smaller one,good luck i hope this help,s.

Nevr head of it, but i get the concept . thats a lot of watts for 12volt sys .
thinking it has to circulate the coolant .

1000 watts is huge , can you get a 750 ? people no longer recommend using them for the reason you mentioned

Check the radiator cap the pressure valve might not be in good shape.also check the thermostate valve
