Dino Coolant Lines

I’ve been methodically servicing this low mileage Dino I have at the shop. It’s in great mechanical shape because of the low mileage, but there are still some parts on this car that are over 50 years old that need replacing.

One of these things was the rubber hoses that make up the cooling system. Although some of the hoses may have been changed through the years, I could see some original hoses still on the car, including these long rubber hoses that run along the length of the car from the engine to the radiators in the front. They looked good, but I could see some corrosion on the connections to the steel pipes so it was time to replace them and inspect the plumbing. HD HEATER HOSE NAPA Part #: NBH H134 Qty: 16

The messiest thing about this job was all the coolant from the system. Since these pipes were the lowest point, the final bit of coolant had to come out of these connections. I have found the best way for me was to pry open a space for the coolant to escape and leave the the car overnight to drain into a container large enough to catch all the coolant.

Some of the coolant connections showed signs of having never been disconnected from when this car was new!

With the coolant drained now was the time to address the control cables and heater valves for correct operation. I found a couple cables seized or broken in their sheathing along with a heater valve that was sticking from disuse.

I replaced almost all the internal control cables with new ones but left the original sheathing. Connecting the end in the front of the car was the easy part, but sticking my head under the dash to connect the other end to the slider levers in the dash was a whole other struggle!
