After using both I much prefer the SAAB sender in the lower hose.

Because?

I have a switch in the radiator that comes on at 82C and it holds my temps with the 87C thermostat PERFECT. I love it. Sends the signal to the low speed on the 940 e-fan and life is perfect.

No it does not matter

So I finally want to be cool like everyone else, grabbed a relay and some wires from a 940.

However looking at my efan, which was from a s60, it only has two wires going to it, when the fan that the relay was attached to had 3. I read that the red/green are for the different speeds.

Does this mean that my fan is only single speed? I was planning on using the sender in my Nissens for the low speed (possibly swapping for a lower temp one) and then the Saab sender in the lower hose for the high speed.

I would have just grabbed the 940 fan but I am cheap and someone smashed part of the shroud, my s60 one is already trimmed to fit.

Thanks, read this entire thread before, skimmed it again but I'm still kinda unsure.

[Dakar09]

I would definitely lean towards that fan being single speed, but I don't know much about the S60 fans.

Anyone know a place where I can buy the saab t fitting new?

[klr142]

The S60 fan has something else controlling it, or maybe(likely!) something built into it that is controlling the fan speed based on whatever signals it is receiving. It might be better to grab a different fan, Ansel.

[digital.aaron]

Not sure if this was ever mentioned (I sure never saw it anywhere), but if you're removing your fan and fan clutch, please remember to replace the water pump pulley studs, assuming yours has an unthreaded section near the water pump flange. You should replace them with m6x12 cap bolts, otherwise the pulley won't cinch to the flange and you'll end up with something like this:

Boo, well I will probably buy the fan that goes with the relay then when one pops up at the junkyard. I may test it first.

[Manimal]

Ansel, grab some alligator clips and test the fan against your battery, if it spins(and sparks at the batt terminals) when you hook up the wires, then the fan will be fine. Just go to the auto parts store and buy a 5 pin relay socket and relay with 30, 85, 86, and 87 terminals. If it has a 5th 87a terminal, that is fine, you won't use it. You can find those sockets/relays at the jy too, my pockets always end up full of relays and fuses...

Super simple to hook up. The most time consuming part is mounting the fan. I used the + terminal of my coil for my switched 12v source, not sure if that's the best place, but it hasn't failed me yet

just put a 960 efan in the 740,
960 fan and relay
saab T and 92* switch in upper hose-
works great

[audihenry]

Guys,

Got the relay and the fan, but couldn't find the T fitting from a Saab for the life of me. Which models did these come in? Was this in the upper rad hose? Anyone have a photo of what it looks like on a car?

The place I went to mostly had 98+ convertibles and I couldn't find it in any of them, they appeared to be in a different housing closer to the engine. Help!

Mostly late 80s 900/9000, its in the upper hose

correct- you can buy generic T fittings though
saab is just cheapest and fits right

[miguel.760ti]

Also look at the side of sensor and make sure it reads 87/82 or 92/87 and not 115/110 before you install it.

[audihenry]

Hey guys,

Thanks for the response. I scoured a couple of local yards and nothing. However, I found this guy on an LS1 forum, seems like it's a good deal mostly because the yard will ask at least half as much for it and it will be used. In addition, you can just drill and tap the other side and have a dual sensor / dual speed setup to allow for a high and low speed setup with the volvo relay block. Much simpler, and only about $13.

I AM NOT AFFILIATED WITH THE GUY AND I HAVEN'T BOUGHT ANYTHING FROM HIM, JUST TRYING TO HELP EVERYONE OUT.

I sell Saab T-fittings with temp senders for $30 shipped. Plug & play!

This works

Or if you have working a/c and want things to be a little cooler you could wire the low speed to a relay triggered by the a/c clutch.

960 e fan installed in 244, took under an hour, yay!

I have the fan,shroud and relay out of a 940 and I want to know if there is a rad. fan switch other then the 212 on 202 off is available that pushes into a grommet. I haven't been able to find one ( plugs into grommet) that has a lower temperature setting. Anyone know of one? I would like to use that for the high speed side of the fan and use the low side with a Saab inline sensor or could I use a adjustable temp. relay?

On my 84 244ti some times the original pusher fan will stay on for a short time after shut off. What controls that and will using the 940 set up do the same? I like the idea of the fan staying on after shut down because it also helps cool down of the turbo.

Any thought's on what I want to achieve?

i tried to find a push in for my radiator- but ended up using a sab t with a 92 on 87 off switch, on just the High speed setting, but it will work even after the car is off if the coolant temp desires
you can get a jegs inline and tap it for a second switch or 2 saab Ts?
Vw makes some wider ranges of switch
an adjustable is a good option or a radiator fin probe
i have heard of people using a dome light delay relay to run the fan a short time after car cut off

You can set it whatever temperature you want.

I think I will use the Saab Switch for the low speed and the push in switch for the high speed.

I was looking at the Hayden adjustable temp. relays and some had good reviews and some didn't so I'm not sure where to go with that. Are you running the 3653 Hayden? Have you had it in your car for a while?
