Thread: 3.9 v8 temperature sender

Just behind the thermostat on the inlet manifold water branch from the passenger side head are two temp senders. The single wire one does the dash gauge, the two wire one does the ECU.

Yep, it is the way to go - I've got a VDO mechanical temp sender in mine - screwed into the factory location as per what Bee Utey just said - it's easy to spot.

Thanks guys,

so it's just a standard temp sender thread then ?

Without looking I think so - I think it may be 3/8th? Electric sender will probably be 1/8th gas and may need a reducer - I can check in the morning.

Thanks, don't let your coolant out .... I can do that and check I was just being lazy and avoiding making a mess in the shed, then having the re-bleed the thing

I might have a standard mechanical gauge here fitted to one of the old cars that will fit. I might try

Coolant is already out and the manifold needs replacing, so I've got to pull it apart anyway - was going to do it this week, gives me an excuse to get stuck into it.

why is the coolant out Babs?

Had a leak from the thermostat housing. When I went to fix this, one of the bolts snapped off the manifold. I've been trying to get the bastard out for a month but all I've managed to do is **** the manifold. I have another one sitting there, so today's job is to bung that on so I can finally drive the bloody thing a bit.

Got to drop the fuel tank too and fix the sender and replace the lazy fuel pump as well.

I should stop procrastinating and actually go and do it...
