Temperature probe replacement question

[Summershandy]

I just got my rebuilt temp gauge back from Abbott Restoration and it looks great. New capillary tube and probe. I'm quite happy as I thought it was going to be a couple months yet. They recommended changing the bushing in the engine from steel so they supplied a brass one. Should I put any sealant of any kind on the outside of the bushing threads where it goes into the block? The silver nut just holds the probe and seats in the bushing with no washer or o-ring, just metal against metal. This is my first so I thought I'd give a shout out. Thanks!

I guess I'm going to try some Permatex high temperature thread sealant on the brass bushing.

 

"Resists leakage, vibration loosening, moisture, hydraulic fluids and diesel fuels. Lubricates threads for easy assembly and disassembly. Wont shred or wear like Teflon^® tape. Temperature range -65°F to 400°F (-54°C to 204°C). Contains PTFE.

Suggested Applications: Head bolts into through holes, oil PSI sending units and sensors, oil and coolant lines, fuel fittings, rear axle fill plug, brake, and power steering fittings

 

Permatex products are readily available at our local stores. Incidently, when I removed the old bushing it turns out it's also brass. I'm thinking someone in the past already did this. I want a nice clean seat for the new sensor to sit in so I'm replacing it with new anyway.

looks like excellent workmanship, can you say what the cost was ?

From speaking with the owner Bruce, they sound like they take pride in their workmanship. It was around $200 and mostly labor. He also sounded quite knowledgeable on the subject. Checked the specs of my engine and calibrated accordingly. Remember, I didn't have any cosmetic work done to the gauge in the dash at all which they do. I merely wanted the gauge to function properly. It was the last piece of the puzzle to have all mechanics working. Proof will be in the pudding when the car's ready to go again.
