This heater is 1 5/8” and fits 70’s era small block Chevy engines
This is a great frost plug heater. I like the plug connector at the heater, there is no issue with the wire getting pinched or twisted and when installed the cord is facing the front of the engine. For a 600 watt heater, it really does a great job, so well in fact that my 1972 Chevy K10 with a 350 engine is too warm to engage the thermostat controlled high idle on the Holley carburetor.

Works very well.
Used this on an International 464 tractor that wouldn't start in this recent bitter cold snap. Very easy to install, pop out a freeze plug, put it in and tighten the screw, refill coolant. Took maybe 1.5 hours and the coolant and block were nice and warm.

Great block heater.
Very well made block heater. I just ordered the wrong size. Will be doing a return and reorder.

Great product, good price.
I live in Tennessee. It doesn't get super cold around here so this 600 watt block heater is ok for my m1097a2 military humvee. But if you live further north I would advise you buying the 1000 watt version. The 1000 watt will keep your block water temperature around 120 degrees.

Installation a bit messy, but well worth it!
These are really nice I have used them for a long time. I plug my vehicle into a timer which is set to come on 3 hrs before I start it. Starts easy when temps fall below 0 and the heater is ready to go!

Junk
Absolutely junk. The o ring was broke, had to put a new one on that I had. The metal gaurd around the plug fell off in transit but I still needed it, so I put it in anyway and the bolt stripped out with a screw driver as I tightened it up. Not even tight. Had to take it out after ears have been bent down but wing nut wouldn't back off. Took forever to get it back out and had to go to town anyway.

Great Fit, No Leaks
This was an easy install in my 84 Chevy 1 Ton 4X4 diesel. The cord was long enough to route safely away from hot or moving parts and still reach through the grille with slack to spare. Well worth the price and the time to install.

Works great
I've had one in my 350 Chevrolet truck for 4 years still works great. Starts rite up on below 0 days no problem. It wouldn't before I installed this block heater. No worries in winter. And that's nice.

Perfect OEM replacement
Works as intended. Once you've got the coolant drained out if the box it's a quick and easy install.
