Just a little info/tip for TR6 owners.
On Friday afternoon the temperature gauge in my TR6 went all the way to the top. A quick check under the hood revealed a slight drip from the right angle hose that attaches to the lower leg of the water pump housing. In other words the lower line from the bottom of the radiator up to the water pump housing. I added water to the radiator and drove home.
The hose was falling apart. Which surprised me because it is less than 6 years old. It was advertised as Kevlar Reinforced.
I was disappointed because I wanted to drive some over the holiday weekend. I removed the hose and went to NAPA hoping to find a hose with the right diameter and a right angle bend. It turns out they carry a hose for a 75 TR6. PN 8632 Hose - Radiator Lower Cut to length.
The hose is L shaped with enough material on the short leg to get a little further onto the pump housing or the hard pipe. The bonus is the long leg has enough to not only get a little further onto the hard line\pump. It also has enough left over to replace the hose that connects to the lower outlet of the radiator.
In my case that hose was showing signs of deterioration too. Curiously the upper radiator hose was completely intact. Same source, same Kevlar reinforcemant. The only difference was the lower hoses have some oil on them from the chronic drip at the front of the engine.
The last time I flushed and refilled the cooling system was when i installed those hoses. So I decided to drain, pour in the flush, fill, drive, drain, fill, drive, drain, fill.... at least twice more than recommended to ensure the system was clean and the water crystal clear. My radiator does not have a drain spigot. Removing the lowest hose is a bit of a pain. I found it easier if I unclamped the right angle hose first. This is the hose that originally went bad. Then removed the hard line from the lowest hose and the pump housing at the same time. It just seemed a lot easier to remove and to reinstall than trying to remove the hard line from the short lowest hose.
