Questions about the thermostat test holes in the radiator - M1009 / Chevrolet Blazer K5 6,2 Diesel

[Elektroman99]

Dear Steel Soldier Community,

I have a question about the cooler. The thermostat tester is attached to the radiator on the right-hand side, seen from the driver's point of view. I think there are still 2 blind openings here. I call blind openings openings in the radiator that are closed by a screw, do not provide a thermostat sensor on the M1009 K5 6.2 L diesel engine. - Unfortunately I don't have a good photo of the direct side view -.




Does anyone know the thread size of one of the blind holes or where in the TM I can find out the thread size?

Best regards

I believe the two openings on the back of the radiator tank is 5/16th Inverted Flair.

In other words, brake line fitting...
Fairly easy to screw in and test too.

Looking around, I found a vendor that might have some Chevy Truck parts.

@Mullaney - Are you sure? Is there a TM somewhere about the M1009 thermostat where the thread type and size is named?

Does anyone else have documentation on the thermostat sensor or the thread in the radiator?

Maybe is it right time for you to buy thread comb?

Maybe I jumped into the discussion in the wrong place.

Are we talking about the spot on the passenger side of the radiator where the probe sensor is? About a third of the way down the "engine side" of the radiator maybe? PAOZZ 11862 358375 PROBE ASSEMBLY,TRAN is called out in TM9 2320-289-20P on Page 64 and TM9 2320-289-34p on Page 81. Part numbers are there, but I don't see thread size any where in those documents.

Sorry I couldn't be more useful.

First of all, thank you, unfortunately the thread of the "GM 358375 COOLANT SENSOR" is not named, too bad.
