Bigj66 Posted October 6, 2020 Share Posted October 6, 2020 Does the 2.25 temperature sender have a 5/8 UNF thread? If not does anyone know what size it is? Quote Link to comment Share on other sites More sharing options...

Landrover17H Posted October 8, 2020 Share Posted October 8, 2020 (edited) Here we are: Whilst it's not critical, all you really need is to watch for a change, likely either your gauge or sender will be out of wack, thus a collection of 10 Ω resistors helps if you see an over-read. Bit of Ohms law will work out what you need if it under-reads.

Bigj66 Posted October 8, 2020 Author Share Posted October 8, 2020 I’m hunting around for an in-line hose joint with a threaded adapter for the sender to screw into. 3/8 NPT seems to be a common thread size. If I can’t buy one off the shelf I’ll get a nut welded onto a piece of suitable pipe. Quote Link to comment Share on other sites More sharing options...

Nothing too difficult it’s just that the Thor V8 manifold doesn’t have a port for the series temperature sender so I just need to find or make an in line unit to keep everything standard with the gauge.

Okay, but where are you putting it? You can't have it in the radiator hose. It will not read engine temperature there. Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted October 8, 2020 Share Posted October 8, 2020 Probably a very stupid suggestion but I have some radiator hose with smaller off take where your sender might be able to be jubilee clipped in your welcome to it if you think it's any good regards Stephen Quote Link to comment Share on other sites More sharing options...

The thermostat is in a different location on the Thor so I’m hoping I can get the sender fitted in line with the outlet that’s attached to where the thermostat housing is on the earlier engines. Alternatively, I could buy the MS thermostat housing adapter and fit a standard V8 outlet but I’m not sure whether the hole that’s tapped into it is too big for the series sender.

Stellaghost Posted October 8, 2020 Share Posted October 8, 2020 (edited) If hole is bigger you could make or buy a reducing bush, if they are bspt I could sort you one out regards Stephen Edited October 8, 2020 by Stellaghost Addition 1 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 8, 2020 Share Posted October 8, 2020 Where does the Thor gauge sender normally live? Or does it use the ECU to power the gauges? Quote Link to comment Share on other sites More sharing options...

Yes, I think the vehicles it’s fitted to have an electronic setup using the CTS. Quote Link to comment Share on other sites More sharing options...
