Title: Temperature sender
Post by: BazaJT on 31 December 2015, 22:14:16
I now have a radiator fan temperature switch[the one immediately below top hose]this has come with a sealing washer on it which is fair enough.I also have the ecu sender that fits in the coolant bridge,this has come with a metal[?]washer which again is fair enough.To complete the set I also have the sender unit that also fits in the coolant bridge,this has come with no washer/seal at all.Should it have one?According to St.Haynes you should recover the seal[where fitted]so do all cars not have them?Could do with knowing whether I need one or not before I get it all apart to fit these new bits.Also according to St.Haynes the sender unit should be torqued up to18nm,is this critical[like the cam cover bolts]?Or is it a case of just making sure it's tight?

Most old styley temp senders area tapered thread so a nip is good.

Are we talking about the ECT Sensir here?

If so a new washer can clearly be seen on my new ECT in the following guide . . .

I think we talk about the dash meter sensor.

I would put a smear of sealant on the threads to be sure of getting a leak tight seal. Don't give it more than a 'nip' else the tapered sender will happily apply enough force to split the ally casting.

Just had a look at your guide Webby,while I've got one of those to go on[it's been too damn cold here for me to be stood at roadside fixing things today]It was the other one with the single wire that feeds dash gauge that I wasn't sure should have a washer/seal on it.As you say Haynes don't seem to state a torque figure for the one in your guide,but they do for the other one and I just wondered if this was a "critical"as with the cam cover bolts.
