What stuff did you use? If it's the fire rated stuff, it's a safe bet that it won't come off, but the other **** gets brittle the older it gets
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
Not a bad job. But if you don't want to end up on redneck.com or the CMT channel. Then do this:
Get a can of Black spray paint for about a buck and get a box cutter from the dollar tree in the 3 pack with the extendable blades.
Trim of the stuff so it looks flush.
Then paint it over.
100% cosmetic. And will look like it was stock.
If you never plan on showing of your ride. Don't worry about it. Call it a day and be happy.
About how you wire in your fan. Try to use the audi temp switch. If you can't. Then go with another way of making automatic unless you plan to be the only one driving the car. And have a good memory to turn it off when the car is off. Or make the really only function when the car is on the ACC/on position. That will prevent a dead battery.
If you ask me Killer job man. The heat should not bother the foam. And it should last for many years.

For a thermostat, are you guys running a radiator probe or a thread in type thermostat? Which one did you use and where did you put it at? My fan is going into an '85 NA 240. I also pulled a fan off of a 95 Buick Century, so I'll need to hurry and get this done to see if I need to exchange the fan in case it doesn't fit.
It is the opposite. Not any of the 700/900/850 cars have the high speed set up to cool the engine under normal conditions, only for excessive over temp conditions.
Low speed for normal engine cooling from the temp switch (or CTS thru the ECU) and high speed from the a/c pressure switch and/or over/excessive temp sensor in the radiator (wired in parallel)
Having the high speed cycle for normal cooling will run large spikes of current going on/off all the time. The 2-stage power control fan relay is designed to reduce start current going from low to high, not from not on to hi speed. It will wreak havoc on your charging system if you wire it this way, as will not using switched power to the relay so the fan has run-on when the car is off.
Searched in this thread, and could not see a comment on if there is a MPG improvement? If not and you are N/A, why do it? (Except for perhaps less noise...?)
Still haven't done anything to my car other than make it not run right, but been pondering anyway
Anyone run a saab T in the lower hose WITH the T for the water cooling on the 240 turbo? it doesn't look like there's much room and 2 T's in one hose seems excessive and probably leaky.
Should I just trigger it some other way or get one of the hoses off a 940 turbo where the junction is rubber and bend the hose? That's what I did for the upper water cooling line after the old one blew a leak.
Search the thread for my posts, I use a threaded 87/82 switch in my radiator for the low speed with the 92+ 740/940/960 fan setup and it works perfectly with the 87 t-stat in the engine. Always keeps the temp gauge in basically the same place. Car is quieter and consistently faster with the efan. I love it and will eventually get around to doing it on my DD "beater", but I'll have to cone up with a different switch setup as that car doesn't have the hole in the radiator...I like my setup...
I just need a colder switch.. My current switch is 92/87,
I need a step lower.
I run low speed to the switch, threaded to the 3 Row CSF ALuminum Rad..
High speed to a switch on the dash. Thermostat peaks at over 9pm on teh gauge, with just low speed.
..
Though checked with an I/R thermometer its not over 195 on the THermostat housing or head...
I am running a 100amp Bosch Alt.

So you have two switches?
Pics?
I don't want to try switching out fan switches at this time because I would have to flush my coolant.
One switch, in the upper passenger side of the radiator. It grounds the low speed circuit of the 940 fan relay. Works perfectly.
Mine only runs for about 12 seconds right when I turn the car off, and only when I ride it hard and put it away wet and hot. If your fan cycles 2-3 times when the car is off, I'd say something is up with that.How often does the fan run when the car is off? I've found that mine tends to cycle 2-3 times and recently, in the hotter weather, the car is getting hard to start. I'm assuming that it's because the fan is running for really long and draining the battery.
