TR6 – TR250 Cooling System Components

Water Pump Information

Here are a couple of important points that you may not be aware of:

During the 1960s and 70s, it was possible to purchase a kit of repair parts to overhaul your old water pump. This usually included a shaft & bearing assembly and the spring-loaded main water seal.
Overhauling your existing pump made a lot of sense. All the pumps made back then were of substantial cast iron construction and had either a cast iron or brass impeller. The main components would last a lifetime.
Nowadays, our throw-away society has extended to sports car water pumps.. These newer pumps aren’t as nice as they once were.

Unfortunately, there are no longer any water pump kits available (except for TR7). We still do carry the spring-loaded main seal for the TR’, but none of the other needed parts are available.
We stock replacement pumps at affordable prices for almost every MG or TR (plus some other British models).

Here is your typical TR’ water pump once you’ve dismantled it on a hydraulic press.
MG pumps are similar, though the shape of the parts is different.

Here is the “business end” inside a TR6 water pump. You can see the dark coloured seal assembly hanging on the shaft. You can also see the narrow, shiny, seal contact face on the inside of the impeller. That seal is spring loaded and it rubs on the polished face on the back of the impeller. This is where water sealing takes place inside your water pump. The face of the seal is either carbon or ceramic. The seal body is rubber and contains a coil spring which pushes the sealing piece against the shiny smooth ring on the back of the impeller.

If the impeller sits all winter and gets rusty, guess what? The rough, rusted impeller grinds away the carbon seal until it fails. Water then leaks into the bearing and destroys the pump. Water also leaks out through the “weeping hole”. Since the cooling system is under pressure when you drive, any leaks will quickly empty your cooling system.
Continued driving with a leaking water pump will cause engine damage and probably crack your cylinder head.

Installing a new Water Pump

-Before installing a new pump, always flush your cooling system to remove scale, rust, and other contaminants.

-After installing a new pump, AND BEFORE ADDING ANY COOLANT, run your engine dry for ten seconds or so. This will help bed the water pump seal onto the impeller sealing face. This will prevent water leaks that might otherwise occur.
Don’t continue running your engine dry for longer than this or you will cause engine damage.
After this brief “bedding-in” period, refill your cooling system with the correct mixture (usually 50 – 50) of antifreeze and distilled water.

Water pumps that have been installed and run-in dry for a few moments almost never leak.

Water pumps that are installed and not run-in as described OFTEN leak.

PUWATERQCP749
TR6-TR250 Water Pump
Single pulley pump, correct for most 68-71 engines.
Comes with a 3/8” pulley groove.
PU-WATER-QCP749 

PUWATERQCP2050
TR6 1972-1976 Water Pump
Double Pulley Pump. While it makes for more confusion, most 72-75 TR6’s were equipped with the double pulley water pump even though they did not have an air pump in this country.
Comes with a ½” pulley groove.
PU-WATER-QCP2050

FBBELTQBB1125
TR6 72 – 75 Fan/Alternator Belt
Fits most Canadian cars with double groove water pump pulley.
1/2” wide belt.
FB-BELT-QBB1125

TR6 1976 Fan/Alternator Belt
This is also ½” wide. (It is about 1” longer than the earlier belt)
It only fits 1976 cars with an air pump (or American 75-76 cars with air pump).

ENRAD308850
TR250 – Early TR6 Radiator
A new radiator will help keep your temperature under control during those sweltering days this summer.
Your existing radiator is probably past its prime. Whether the fins are squashed flat, or the tubes are leaking, a new radiator is sure to help.
A not so obvious fault of older radiators is plugged tubes. You can’t see this sort of trouble without having a rad shop take apart your old radiator.
While you might not equate the cooling system with oil pressure, a lousy rad will cause overheating on a hot summers drive. This will exacerbate that Triumph tradition of having extremely low oil pressure while idling at a stop light.
We just recently got early TR6 rads into stock. They were previously unavailable.
TR6 radiators are all the same size and shape. The difference is in the hose nipple locations and the direction that they point in…
Supplied with 10mm drain plug. Original drain tap will NOT fit!

ENRAD312347
TR6 72 – 75 Radiator
This is the most common TR6 rad.

ENRADRKC1735
TR6 Radiator – Canadian 1976 cars only
Starting in 1975 for US cars, and in 1976 for Canadian cars, the TR6 underwent a few changes.
Exhaust air injection was added to enhance emission controls. This necessitated the installation of an air pump, as well as all the complicated “plumbing” that went with it.
In order to fit the air pump onto the front of the engine, the alternator mount was altered. The thermostat housing had to be modified. This required a radiator with a curved upper hose fitting and a different upper rad hose to match.
Otherwise, both early & late radiators are identical. Because of the change in the upper hose fitting, they are not interchangeable.

HOKITHK39G
TR6 69 – 71 & 72 – 75 Green Radiator & Cooling System Hose Set
TR6 enthusiasts that are sticklers for details, often call for green hose sets. We have them in stock now…
They are made by gluing a painted or dye coloured canvas wrap around a black rubber hose. I still have a couple of brand new Unipart hoses from the 1970s. These new production hoses look practically identical to the originals from fourty years ago.
Set includes:
-Upper Rad Hose (This is the one-piece hose originally used on 69-71 cars)
-Both lower rad hoses
-Front hose (water pump housing to intake manifold)
-Rear hose (return pipe to intake manifold)
-Rear Hose (Return pipe to heater firewall fitting)
-Heater hose, valve to firewall fitting (the straight hose)
-Heater inlet hose (under dash)
-Heater outlet hose (under dash)
Please note that the two under-dash heater hoses are black as original. All of the other hoses are green.
This hose set is original on any 69-71 TR6. Makes an excellent choice for most 72-75 TR6s in Canada too. Originally on 72-75 cars, there was a metal “T” fitting in the upper hose. It was a complicated affair with a thermostatically operated valve and several vacuum hoses attached. On most cars now, it is either missing entirely, or else it is not functional. Because of this “thing”, the upper hose was cut into two shorter pieces. The hose set offered here incorporates the longer one-piece upper hose. Unless your car is very original and still has this vacuum valve plumbed into it, the earlier hose will look a lot nicer and have half as many hose clamps to potentially leak…

We now have green hose sets in stock. TR6 enthusiasts that are sticklers for details, often call for green hose sets. We have them in stock now…
They are made by gluing a painted or dye coloured canvas wrap around a black rubber hose. I still have a couple of brand new Unipart hoses from the 1970s. These new production hoses look practically identical to the originals from thirty-five years ago.
Set includes:
-Both upper rad hoses
-Both lower rad hoses
-Front hose (water pump housing to intake manifold)
-Rear hose (return pipe to intake manifold)
-Rear Hose (Return pipe to heater firewall fitting)

-Heater inlet hose (under dash)
-Heater outlet hose (under dash)
Please note that the two under-dash heater hoses are black as original. All of the other hoses are green.
You can use the earlier hose kit listed above if you are willing to cut the upper hose in half (or alternatively forgo and remove the vacuum valve that it originally teed into the top rad hose)

HOKITHK42G
TR6 1976 Green Cooling System Hose Kit-also fits US 1975 cars
This green hose kit fits any 1976 Canadian model TR6. May fit a few 75 cars too. If your 75 TR6 has an air pump and exhaust air injection, this is the hose kit for you.
This kit includes all the same hoses as the 72-75 kit advertised above, with one exception.
This kit includes a one-piece upper radiator hose. This hose is also a different shape to match up to the curved outlet fitting on the top of the late model radiator.
