Blanking plug standard - original - radiator - M1009 / Chevrolet Blazer K5 6,2 Diesel

[Elektroman99]

Dear Steel Soldier Community,

I'm hoping that the forum's wealth of knowledge will enable me to avoid one of the steps.

First of all, an explanation:
I would like to install a second sensor to determine the temperature of the cooling water in addition to the "factory-installed" cooling water sensor in the radiator.
I know that the radiator has one or two blind plugs on the left-hand side when viewed from the front. It has to be said that I assume it is the original radiator fitted at the factory.
I just want to avoid draining and refilling the cooling water before fitting the second sensor, hence the question here in the forum.

Does anyone here in the forum have an empty original radiator or a vehicle in assembly in which there is no coolant and can tell me the thread size and standard of these "dummy plugs"? If anyone knows the place in the technical information and manuals where these are named, please let me know (name of the document and page).

I would be very pleased to receive your answers or references to further information.



Best regards

The coolant sensor is in the head, not the radiator. Download the TMs from the SS TM area, and it will tell/show you the location in the removal/install task.

If you want an additional sensor for somethinglike a physical/mechanical gauge, the heads are identical, so there's an unused coolant temp sensor port on the opposite side. Leave the radiator alone unless it's broken.

The radiator is downstream of the thermostat. It seems as though any additional temperature sensor sensor should be upstream, either in the other head in the unused port like Jeepadict says or in the coolant crossover if you have a spare port there.

I know of no unused ports in a stock radiator

I know that you are the CUCV and Blazer expert. Is there really no way to use a "blind plug" directly on the radiator, an unused inlet or outlet pipe in the radiator to fit an additional sensor?


@Jeepadict
Thank you for your reply.
This thread is basically about an additional sensor.

Can anyone tell me where (name of TM and page) I can find more information on this?
Unfortunately I have not found any information. That's why I'm asking here.



OK, I'll rephrase the question a little:
Can someone a) name me the TM - and page - where the standard factory fitted cooler, with the various connections and threads is named?
b) Which connections, outlets or inlets are unused on the M1009 and can be used for an additional sensor connection, what threads do they have?


Best regards
