Does the temp sender provide an earth when it’s up to temp - or lose the earth, De-energising the solenoid and allowing the spring to open the CAS?

I'll have to check that when I'm next to the car.
In a Sierra, you can apparently hear it do a very fast series of clicks when you turn the ignition on

Just been to the car Jim, and you were correct. The temp sensor is a closed circuit when cold, and breaks the earth when it gets hot. So presumably its ignition live to one side of the solenoid (via a relay??) And the other side to the sensor. So the cold start solenoid clicks in at start up and will go off when up to temp.
I've tried it wired direct and the solenoid certainly clicks anyway.

According to the circuit diagram the temp. sensor (3) feeds into the EGR and the Relay is driven by the EGR. However, if there isn't a relay then there must be a separate temperature switch which closes the circuit to earth. Should work OK, but it isn't what is shown on the circuit diagram.
Good luck - hope it all works.

There are 3 temp sensors. One for the fan, one for the gauge, and one for the cold start thingymabob :w :D

It’s a Ford box of tricks - does something very simple yet is designed to make you think “best take it to a dealer”.

Who will just swap random bits at your expense anyway.

Seeing as you're al being helpful.......next conundrum.
Can anyone suggest a flexible pipe suitable for the turbo oil feed?
The original is a solid pipe with banjo fittings, but has been damaged so if I cant fix it was looking at chopping the 2x ends off and putting something flexible between. I have some stainless over braided fuel line, but not sure if that's going to last?

Feed pipe so I’d guess 1/4” or 5/16” at most?

Corky got some made up for his but Cheshire standard braided stainless snazzy stuff. I’m guessing it’s an oil cooled turbo so needs to be high temp which sort of leans to braided Teflon stuff IMHO.

I'd buy a new std. pipe, but yes you've guessed it.....NLA.

IF you have about one inch of pipe from each banjo and a new length of copper pipe (fuel pipe?) that slips over, then soldering would be strong enough IMHO.

There are lots of braided oil feed hose kits on eBay. They generally come with a pair of banjo fittings with JIC/AN hose connectors and an appropriate length of braided hose.

Kinugawa stuff is generally very good.

Well I decided to allocate an hours time to swapping the oil filter housing today, back to the Turbo version with cooler and oil feed.
Well, it doesnt fit ☹, as some fool put a chassis leg in the way . Only solution (a £100 solution) I can see is a remote filter, and hope that will clear the chassis 🤔
At least I got 2x new belts, tensioners and idlers fitted instead.

Diesel Dick lack of lube

Post by philhoward » Sun Oct 11, 2020 4:31 pm

Drop the cooler?

Either that or get canny with an oil filter catalogue - there will be a much shallower one I’m sure. scimjim is (was) using one from a BMW i3 on his Zetec in the SS1 for that reason (about 35mm deep instead of the 80mm or so of a stock filter).

I thought the cooler was needed as standard equipment? Good shout on the small filter though, certainly worth a try.
If I have to ditch that cooler I presume a small remote one would do the job the same? In fact, would a big brush one work, as have several of those :D
Thanks.
