I'm going to go ahead and ask one of the stupidest questions possible. I've tried to avoid the issue, but I can't avoid it any longer. The radiator cap on my 412 just will not come off. Am I missing a trick here, other than just pushing down and twisting counterclockwise? There is no movement regardless of what I try; none whatsoever. I'm afraid to go at it too hard, for fear of breaking the joint where it's attached. There's more to this story, which I'll save for my second stupidest question. One thing at a time however...
So, I ended up cheating. This is actually an oil filter tool, but it worked. Unfortunately, what I found isn't good. The radiator is full, but we're not cooling. Image Unavailable, Please Login .
I'm pretty sure that the cooling fans aren't working. Actually, I'm certain of it. This leads me to my next stupid question - where are the fuses? The owner's manual tells me which fuses I should be looking for, but not how to access the fuse panel. I'm a noobie. Plz be kind.
My third stupid question is how to get into a locked glove box (no key), but right now finding the fuses are more important.
Yes. I didn't understand what the manual was showing me. It's the entire footwell. The whole thing. Lesson learned.
I have to assume some of these wire splices aren't from the factory. The fuses that I was looking for all check OK, so moving along... Image Unavailable, Please Login
Rifledriver, you are correct. It was clearly shown on pg45. I was only looking at the fuse layout on pg107, so I was in the wrong section of the manual. Image Unavailable, Please Login
The fuses check out for all three fans; we have keyed power. Can the fans be tested by crossing the wires at the temp switch?
If you start the AC one fan will start regardless of engine temp. You can short the tempswitch to test the three fans.
Thanks Raemin. Confirmed. All three fans do work when the wires are crossed. Looks like I've got a bad temperature switch.
What's the coolant that everyone recommends? AGIP antifreeze is listed in the Owner's Manual, but it doesn't seem to be available any longer. There's an AGIP Permanent Spezial, but I'm not sure if that's the same thing. It looks like it's currently filled with regular, green-flavored coolant.
SIOat coolant mixed with distilled water and water wetter. The point is to reduce cavitation, protect the liners, and transfer more heat. This plus a new radiator cap (1,1bar) for the higher pressure required to prevent the water from boiling. https://www.ferrarichat.com/forum/threads/cooling-enhancement.629805/#post-148700576
In the process of troubleshooting this cooling issue, I managed to snap this vacuum hose. Honestly, I think after 38yrs., it had been waiting to give out, and just needed a nudge. What is this, and how do I replace it? Image Unavailable, Please Login
Its not a vacuum line, it is a high pressure fuel hose. Dont start the car, you'll have a fire. It requires some special tooling to fabricate.
Thank you for the heads up. I came to the conclusion this was part of the fuel injection system, but not that it was a fuel line. I had avoided touching this car for almost 8 months. Now I remember why it's been sitting here so long.
I'm trying to decode the parts breakdown for this online, and can barely tell what I'm looking at. Is this a "bridge hose"? Image Unavailable, Please Login
The best thing you can ever do to get the correct parts for the car is deal with a knowledgeable parts person and describe the part you need. Let him look it up. If you are dealing with the right person he knows way more about parts than you or me.
