Should I put the temp sensor on the upper or lower radiator hose? Or does it matter?

Oh man, definitely hear that, been there plenty myself.I’m going to do all that when I redo the head gasket. I’m just trying to get the cooling sorted to limp it a long for a month until I have the cash and access to another car.
If I'm remembering right, coolant flows out of the top hose to the radiator, bottom hose is return to the engine. That's where I'd put it, top hose.Should I put the temp sensor on the upper or lower radiator hose? Or does it matter?

I’ll check the heater hoses tomorrow. Thanks again for all the help!Bottom radiator hose is after the coolant goes through the radiator and gets cooled down, it may not get warm just sitting there at idle. Is your heater blowing warm air? Heater hoses getting warm? If so, coolant flow is fine.
Sitting with the idle up on: Heater hoses are hot, regular gauge gets to operating temps, and lower hose is cool. Took it for a short drive (3 times around the block): regular gauge stayed at normal operating temps and lower hose got to 98 degrees. I think I’m ok for now. Gonna take it on a longer drive to see what happens. Gonna have the oil tested to confirm blown head gasket. In the mean time gonna start another thread because now I have another issue! Can’t win for loosing!Bottom radiator hose is after the coolant goes through the radiator and gets cooled down, it may not get warm just sitting there at idle. Is your heater blowing warm air?

Yes, I will do the block test but I read on another forum that it can be inconclusive due to diesels having different exhaust gases than a gasoline engine. Blackstone industries will test the oil for coolant. Thanks for the help!You want to be testing the coolant for combustion gases, not the oil, to confirm head/HG issues
The last couple of blown HG I've had through here have had perfectly clean oil hence the coolant suggestion, but oil analysis is never a bad thing.Yes, I will do the block test but I read on another forum that it can be inconclusive due to diesels having different exhaust gases than a gasoline engine.

Gotcha, thanks for the help! Time will tell!The last couple of blown HG I've had through here have had perfectly clean oil hence the coolant suggestion, but oil analysis is never a bad thing.
All the test kits I've used say they work on anything, but might depend on how that particular test works I guess
