ClassE Posted June 10, 2015 Author Report Share Posted June 10, 2015 Are you keeping the oe aux fan? If not it's super easy. Replace the fan switch on the passenger side of the radiator with an 80/88c one (stock is 91/99c) from a 318, its plug and play. The hook the large wires that go to the oe fan to your new one.Sent from my potato phoneWas the old electric aux fan JUST for the A/C system, or was that thermo switch there as a "safety net" to the fan clutch (if the fan clutch failed and the thermo switch hit its temp - it would kick on the elec aux fan?!?).If so - what you're describing makes perfect sense. Swap to a lower temp switch, and it'll treat the old aux elec fan as a primary cooling fan. Then it's just splice in the new fan and call it done. I'm just confused by if/what I need to change with the thermo switch (if at all?)wiring is my least favorite thing to work on in a car. Eventually I'll need to bite the bullet and wire up a JB4 and meth kit so I can spray, but definitely not looking forward to it. The above instructions make perfect sense to me, however, it doesn't sound like you have exactly the same parts/setup. Without a way to visual what's what, I can't be of much use. If I could see what wires run where and how they are connected to the sensors it would make more sense Swing through Oshkosh tonight - drinks are cold.

No cutting of anything except the actual fan power wires to connect them to the new fan. You can verify your thermoswitch is correct, it should have stamped on one of the hex flats "80/88". If you were really fancy you could get a 2 speed electric fan. I will try to look at a diagram tomorrow to see if the low speed relay turns off when the high comes on. If they are just both on in a high temp condition you would wire it to the low speed circuit. I just kept the oe aux fan on my e36 so it had low/high. But the e36 aux fan is way better than the e30 one. Sent from my potato phone Quote Link to comment Share on other sites More sharing options...

ClassE Posted June 12, 2015 Author Report Share Posted June 12, 2015 Well.... Took a one hour break for dinner and some play time with the kids - other then I've been wrenching since noon.She's back on the ground, oil changed, coolant system burped and working, elec fan works, front lip is on.... Only thing left to do is get the hood on and drive it - neither of which I can do because I don't have a helper at 11pm and it's raining outside.So after work tomorrow will be its test drive... All I can do is cross my fingers and hope for the best. DrLeadFoot 1 Quote Link to comment Share on other sites More sharing options...
ClassE Posted June 12, 2015 Author Report Share Posted June 12, 2015 Test drive couldn't have gone better. Drivetrain vibration is gone, no squeals or noise from anywhere... Overall feels fantastic.No power steering under 5 mph kinda sucks, but if you're moving its totally fine. B C 1 Quote Link to comment Share on other sites More sharing options...

ClassE Posted June 13, 2015 Author Report Share Posted June 13, 2015 Can't thank everyone enough for the help since I got this car. Some of you have had to endure painfully stupid questions via call and text - and for those people I'm eternally grateful. Earl, Brian, and Andy (and really everyone who's helped me with this) - I truly appreciate it. andyhundley 1 Quote Link to comment Share on other sites More sharing options...
ClassE Posted June 25, 2015 Author Report Share Posted June 25, 2015 Backed the E30 outta the driveway in Saturday, and noticed a nice drip line from under the car on the pavement. As I sat contemplating what it could be for a second - I slowly watched it evaporate....."Oh crap..."Straight back into the garage.Found the culprit - and got it replaced tonight:Replaced the filter and both lines running to/from it. PO at some point apparently thought a kinked straight line would be fine. Quote Link to comment Share on other sites More sharing options...
ClassE Posted July 2, 2015 Author Report Share Posted July 2, 2015 Ordered all the parts last night to make a temporary intake for the M20 (so I can remove the AFM and stock air box - and have a good mount for an AIT).Trying to win the "Biggest Goddamn Filter We've Ever Seen" Award at EuroWerks.

ClassE Posted July 11, 2015 Author Report Share Posted July 11, 2015 Is that to slip over the velocity stack?Yup! Unfortunately, the velocity stack I got does not match the dimensions given on the website I bought it from (it's a 6.5" OD, should have been a 7" OD) so hoping they just sent me the wrong one.... But doubt it (They don't offer a 6.5"). Quote Link to comment Share on other sites More sharing options...

GunMetalGrey Posted July 20, 2015 Report Share Posted July 20, 2015 I had thought that I was the only one with the gap between the bumper and upper valance (under the headlights) that reduces near the kidneys.It appears that I am not!

ClassE Posted August 5, 2015 Author Report Share Posted August 5, 2015 Any words of wisdom for removing the forward-most lower intake manifold nut? It's directly behind the heater core hose, and I'll be damned if I can find a way to get to the thing. My assumption is I need to drain the coolant system and heater core - but it's a huge PITA to do so looking for any other ideas. I've used every combination of box wrenches and 1/4-3/8 drive swivel/extension/sockets and it just seems impossible to get to. Absolutely infuriating.
