Tech Question - Swirl pot and water temp sensor adapter

[TREVCOS]

Hi guys, just a quick question. I've got a swirlpot for my car, does that need to be put into the top hose of the radiator? I've also got a water temp gauge adapter (the bit you screw the sensor into), does that need to be cut into the top radiator hose as well for the gauge to read correctly, as I won't be able to put both into the same hose.

My swirl pot is in top rad hose and water temp sensor is bottom rad hose just before it meets the thermostat housing. I only did this as I had to extend the bottom rad hose after fitting an alloy rad and the temp gauge adaptor was perfect size

Does the gauge read okay with the sensor in the bottom hose Steve, because that's what I was thinking of doing too?

Why not put it in the bottom of the swirl pot?

Well I did think about that Adam, but if I tap that is the metal too thin to get a good thread/seal?

Will I get an accurate temp reading with it in the lower rad hose do you think?

Hmmm, I wonder if I could have a bolt style adapter welded into the bottom of the swirlpot and then just screw the sender into that. That's got me thinking......

That's what I would do. Save cutting another hose. I take it your running another temp gauge.

I've only had it running twice and once to test the fans/bleed the system. My gauge showed 92 or 94 degrees I think when fans cut in the warning set on the gauge is at 100 degrees.

Need to find myself someone who's good at welding. I'm fitting another temp gauge Mark, I'm a bit paranoid because my old car had a dicky gauge so I want to make sure I've got accurate temps on this car.
The bugger is I've already cut the lower hose, but I can get another if I need to.

I just wondered if the temp came up from cold to warm at the same rate as the normal gauge Steve.

As I've already cut the hose do you think it'll read okay on that side Mark, just looking for as many opinions as I can get? Or will it always read low compared to being in the top hose?

I don't remember to be honest, but I would trust my Defi more than the standard gauge

My standard gauge had a serious mind of it's own on the old car.

Yes, it would be good wouln't it. I don't do welding though. Anyone a good welder on here that I can send it to to get it done?
