Ferraristi, I feel stupid asking this question, but my system needs to be bled and I don't know where to do it from. I have searched the other threads, and have come across some where they describe where the bleeding should be done, however I don't even know what the bleed screws look like on the Testarossa. My 308 is quite simple at the rad, but on the TR, I don't see a similar type of bleed screw on the locations that are described in previous threads. If anyone has any pictures of what the bleed screws look like, it would really help me. Thanks again.
On the firewall in the middle there is a thermostat housing. On the top in the middle of that there is a brass screw that will take a 10mm socket to loosen. On each side of the engine compartment towards the front there is an aluminum water pipe. On the top of the pipe is a bung with what looks like a brake bleeder screw in it pointing up. On the left side it is a little difficult to see and access because it is next to and slightly below a frame tube which obstructs it. I wold suggest taking the bleed screws totally out of the pipes and coating them with some antisieze. They have a nasty habit of getting corroded and wanting to stay in.
In this picture you can see the bleeder on the thermostat housing in the middle of the firewall. The bleeder screw is just peeking out from under the black grill. You can also see the one on the right coolant pipe in the lower right corner of the picture. There is one just like it behind the air injection pump filter on the left side not visable here.

Thought I would post this here instead of starting its own thread. Looking at an old book and came across this picture of what would appear to be a coolant drain hose is that correct? Was this just used to bleed the system then removed? Image Unavailable, Please Login
That hose is the "SAIAG" imprinted 3.5 - 8mm vacuum hose that would connect to the electro-valve on that side under the fender (on a US car). That's a production line photo so they may have just run the hose and not yet made the connections. Or, as you said they may be using extra hose to bleed the coolant without making a mess (i do that too). If for that purpose the hose is removed afterward. Image Unavailable, Please Login
Amazon sells these air lift kits that purges the air out of your cooling system and then fills it with coolant. Search (air lift coolant) on Amazon. I don't have one but thinking about getting one next time I change my coolant.
Tobbe, vain attempt at humor to Cheif (an in joke) Nitrous oxide, makes one laugh or lift one up. Hmmm Pete
Just doing some service on my car and drained the coolant, noticed a rubber grommet near the base of each rad and looking at the pic it appears this hose runs through it, guess I just figured out another little interesting fact about my car
Here's a thread I did on the complete coolant drain and bleeding proceedure. http://www.ferrarichat.com/forum/boxers-tr-m/278104-changing-coolant-testarossa.html Shamile Freeze....Miami Vice!
Great thread on coolant bleeding. Tried to loosen the Radiator bleed screws, no success. They are too tight, maybe seized, and if I put any more force they may break. The only bleed screw that I can use is the one in the centre on thermostat body. Any suggestions?
but, personally I would not use unless there was no other way. Life Does NOT Suck! vincenzo [ame]http://m.youtube.com/watch?v=lgtax96BH9c[/ame]
Hey Brian, Any comment on the factory picture in post 6. Is that line something they used then removed after they bled the system? Cheers, Jeff
Perhaps my concern is unwarranted.... but, When you unclog a drain with a plunger, you break the plug free by cycling pressure/suction/pressure/suction etc etc. Having used stop leak (as a kid, on a beater), I know that very small particles under pressure are jammed into each of the teeny tiny crevaces and leak points in our cooling systems. They plug microscopic leak paths. I don't want to break 'em free. Life Is Good, vincenzo
