Trying to determine to correct flow of coolant in my 1995 SWB. I have two heater hoses (no valve) just like the early Disco's, one heater hose attaches to the lower Rad Hose and the other Heater hose attaches to a pipe that goes into the manifold. I am thinking the Heater hose that comes from the manifold flows coolant from the engine to the Heater Core and the Heater hose that joins into the lower Rad hose is the return from the Heater Core back to water pump. IS this correct?

I don't want to steer you in the wrong direction, as I have a 94 with a different timing cover. Your answer will be found in the workshop manual. There is a diagram which illustrates the direction of fluid flow through the system. You can get a manual in paper or disk form from British Pacific.

What's the reason for asking the question?

Cheers,

Installing a coolant temp sensor in the heater hose, and I want to make sure it goes into the hose that comes from the engine, and not from the heater core. For no other reason than just to see the coolant temp right after it exits the engine, as opposed to after it has been cooled a bit by the HC. I found my answer, the coolant comes from the intake manifold, then goes into the HC. The manual is not real clear in the diagram for my truck.

It pays to look around thanks for that post as i was wondering the same thing regarding my 1996 Disco, now i know :D

Oh for the love of all that is good in the world, STOP OVERTHINKING THINGS AND JUST PUT THE FUCKING SENSOR IN THE HOSE!

Anything is gonna be better than what we were offered by the factory.

For the second time today, I get to say this. Remember what Lord Kelvin said-"until you can measure, you cannot know", or something to that effect. I have measured the temps using a non-contact thermometer and the temp differential is not enough to be of concern.

I did. Now can you give me your opinion on my oil leak? I am real curious to see your response!
