Temperature Gauge, sending or receiving


One of the things I noticed early on in my efforts to maintain the '76 B was the Temperature Gauge never moved. After driving the car the engine would most definitely get hotter. My first thought was that the gauge must be faulty. I decided to remove it for closer inspection. This is not as easy as one would hope but after twisting and turning my right hand and arm in ways a Carnival side show act would applaud the gauge popped out. Looking over the gauge it appeared to be in good condition, but how does one know?

I found that by connecting the gauge's sending wire to ground the needle would move. This is a good sign that the gauge itself is fine.

So, this would lead me to the sensor (thermistor) inserted into the engine block. I ordered one from Moss Motors, with a few other items of course, and when it arrived I swapped out the old for the new.


I fired up the B and went for a drive. After a few minutes the gauge needle started to climb.


Overall this was a pretty easy process and now I have the comfort of knowing when the engine is overheating before things get out of hand.

Cool ride...

Anyone who has ever driven a convertible in 90-degree weather knows how hot it can get. The MGB is notorious for it's "hot seat" and sweltering cabin space. Making things worse can be the heat from engine compartment and road. There has been much debate about the best method of insulating and cooling the cabin down to create as comfortable an experience as possible. It is my assertion that this is impossible. Well mostly... After some research I decided to try a few things to see what, if any, improvements can be made. I settled on leveraging some simple things like bonnet seals, bonnet insulation pads and most interestingly, Reflectix Foil Roll Insulation , from Lowes. I figured, hey it's cheap and easy, so why not give it a try! So that's what I did... I start by removing the seats. This is not an easy task but after struggling through the bolts holding the seats down, out they came. While they were out I decided to give them a good cleaning and lubing. Th...

USB didn't exist in 1976!

Making the most of your drive time is important. Even it's just for a leisurely run to the market and back. USB is a must! You might want to plug in a GPS, Smartphone, a Fan! Electrical can be tricky in these old cars but with a little patience, knowledge and help from those who have been down this path before you too can install a USB socket in your MGB, today. Process is pretty easy if you already have a cigarette lighter hole in the console and the ability to tap into the power source. Hole available. Wiring, use caution! Tap into the power source. I used Single U-Element Insulation Displacement Connector. You can pick these up just about anywhere. Walmart, Amazon.com, etc... Here's the finished product: I will post photos of the wiring job the next time I remove the console. I will have to do this to replace the courtesy light anyway.

Topping things off...

A new top... One the best things about the MGB Roadster is the cruising around with the top down. There are times when a top is needed, like during a downpour! When I received the car one of things that was pointed out to me was the rear zipper for the window was broken and needed repaired or replaced. I attempted a repair but that failed and since the cost of a new top is reasonable that was path I decided to go. Removing the old the top takes a little work but isn't overly complicated. Most of the places where the material is attached by snaps, rivets or glue. There are several web resources for the removal and installation process so I won't go into detail here but here are some photos for reference. To begin the removal, the top seal that is seated in the aluminum track strip must be pulled out. I found that it was easier to remove the top header bracket. This required removing the 3 phillips head screws.  After getting everything out of the way the next step...
