Looking for a frost plug/ freeze plug heater
I’m having one hell of a time locating a frost/freeze plug heater. I popped a plug out in hopes of getting an accurate Measurement but of course you can’t actually get them out with out crushing them. I’m attempting to make a jig of some sort so I can measure the hole. I’ve got it down to 34-37 mm plug but obviously that isn’t accurate enough. If any one knows the size or the plugs or has a part number for a heater that fits you would be saving me a lot of trouble.
The engine is the 4g94 gdi
MF665541 This is the part
MF665541 This is the part number for the frost plug I ordered one just in case the block heater doesn’t fit. Not a lot of room between the plug and the block
