    Attention All Racers, Street Rodders, and Performance Car Owners...

    JEGS Core Plug Block Heater is the essential item your engine is screaming for! Not just for cold and icy mornings but ideal for race cars too! Preheating your engine's coolant and oil prevents wear and tear on vital engine components by radiating heat to surrounding components, such as engine bearings, valvetrain, intake manifold, transmission, and starter, which will allow for easier cranking and engine starting. Brings the engine to operating temperature quicker by cutting warm-up time in half, saving fuel and engine run time. Considerable testing on Alky-burning bracket cars showed a savings of 2-1/2 to 3 gallons of alcohol warming up on a 60° day! We tested big block Chevy bracket dragsters; one heater heated to a 90° water temperature, and two heaters to a 110° water temp (heaters left on for an hour). We suggest using one heater per side on V8s for quicker heating results. Installs easily into a core plug hole in the block and comes complete with a 4-1/2' grounded power cord.

    Specifications: Provides 600 Watts (maximum) @ 12.5A @ 120VAC

    Rated 2 out of 5 by from Purchased a 600 watt engine block heater for my Ford tractor. Received a 400 watt heater instead. I needed to get this unit running so I used it. Product was good, just not what I paid for.

    Rated 1 out of 5 by from it's only a 600 watt heater I bought this item, which was shipped out in a timely fashion. The item is listed as a 1500 watt in the catalog and on the package. When I opened it was only a 600 watt as stamped on the heater.I returned it and it cost me 7 dollars through no fault of my own. They were supposed to contact and let me know if they were mispackaged as I still wanted one. Never heard from anyone.

    I have a 1974 Slickcraft boat that has a 302 Ford v8 in it and use this into the late fall here in Michigan. IT can get below freezing some mornings white I still have it in the water. What type of heated would be best to keep the engine coolant warm?

    Asked by: steelydann
    This item will keep the engine water warm, but I would check with a marine dealer on the rest of the boat - out drive other components that may freeze.
