Not an expert, but my guess is the only thing it will hurt is your electric bill.

Monkey.......more better a magnetic block heater to yer carb intake manifold. Iff'n you can feel the carb "warm", its done its job. You do know the actual act of carburetion takes HEAT outta the air, don't you???

Hot water don't make engine eazier to start. Besides, wanna guess where all that hot water is going to go??? How 'bout out yer radiator which is designed to COOL yer water. Not good eh? .......Dell, the cool

Does anyone have any experience using the smaller Katts magnetic block heater on the intake manifold. Specifically, doe all the curves and bumps on the manifold allow for enough surface contact with the heater to allow it to do it's job?

I was looking for some welsh plugs at NAPA and found some block heaters that replace the welsh plugs You might see what they have in stock

Monkey,You could hook it to a 24 hour timer and set it to warm your engine up about 2 or more hours before your ready to start it up in the morning.To save on your electric bill.

Unfortunately, I don't think there's a Welch plug heater that is an exact fit for this application.

horsie.......there is NOT enuff room inside the N-Block fer welsh plug heaters .......Dell

lower rad hose heater plugged in for at least 2 hours & trouble light ( 100 watt ) hung on manifold / carb area same time
49 8n starts every time and darn she's cold here in ontario

interesting --- I've used my magnetic block heater to warm the oil so it would turn over easier -- but I like your idea --- that is until my new heated pole barn is done ----

& the 8n would not turn over the other day out in the cold even with the heater -- new battery fully charged -- but nothing but a few sparks out of the starter then zip.

I guess I'll dig into it when I get back from vacation.

I have had the same tank heater on my 8-n for about 35+ years. I put a 5/8 hose adapter in the drain plug on the left rear of the block and bought an adapter that is for 5/8 hose and threaded on the other end with 2 curved washers and a nut. Drill a hole in the lower hose,install adapter, assemble hoses, fill with your anifreeze and make sure there is no air in the heater. I plug it in for 3 or so hours or use a timer. Block gets nice and warm so it starts great. Only 30 below here this morning but thank goodness no snow to blow.

If you are saying that hot water doesn't make (help) em start, you have never been in the cold.

Teddy......trust me, its the CARB and exposed manifold that needs the heat. Yeah sure, hotwater will eventually migrate out the manifold. Yeah, I even have a hot-water heater on my Dodge Cummins Diesel, but its the ELECTRIC GRID HEATER in the INTAKE that makes the diesel start when its cold. Water heaters are fer pansy-asssses to feel warm in the morning.

Having grown up in COLD COLORADO MOUNTAINS, my dad would remove the 6volt battery and take it in the house overnite for better starting of cold blooded 6-cyl flathead Plymouth. The neighbor will haul out teakettles full of hotwater to refill his radiator to get his International pickup going. He was too cheap to buy anti-freeze like my dad did. .......respectfully, Dell

No doubt you need something to help start a cold diesel when heat of compression is what it's all about. The higher the temp you start at with either air or fuel is the big thing. Glow plug for heating fuel, manifold pre heater for air, or both.
For a gas engine with an electric ignition you've got the same considerations on a smaller scale. Your compression ratio is a lot less but you've still got to get the fuel to vaporize and ignite. If you're adding heat to the block with an electric coolant heater it's that much less heat that's going to bleed off going into your combustion chamber passing through all that cold,cold,cold iron. I would also think you'd crank a little quicker with your oil and battery basking in the glow of your warm block.
This is depressing. I'm going to the airport and find a warm sandy beach somewhere.
