Auto Supra Coolant hose pressure and return leak to oil pan and filter area?

[rjSupra]

Hi all:

The quick: have two leaking coolant lines, sprayed all over the ground after two over heat cycles. Coolant lines (small diameter metal) come from two parts of main rad, and then run to above the screw in oil filter and the oil pan to car. If I squeeze the rubber lines that connect from the steel lines, coolant fluid (not oil) oozes out the actual sides of the hose not far from the clamp. Also from under clamp too. Rad empty to the eye from above, again (sigh).
So, dumb question. My cars have always been manual and 'lower' tech. I did not even know oil can be 'liquid cooled' by coolant .(?) Is that what these lines are, and does it seem that replacing the rubber lines should solve my poor cars overheating problem and coolant loss? Previous owner know nothing about HG or if replaced, but oil has always been clear and clean, no smoke ever even on startup. I'll try to dig this up here, but what are those lines called to get the parts? Is the cheapie Autozone or Napa or whatever fine to replace those with? Do steel or steel braided cable exist for them and is that important to use those or is stock or OEM replacement rubber just fine? THANKS!

One other item: I read here about the main fan that's on the alt belt. Someone stated it should not turn free at all shut off, and if so, a bearing in the fan or something is trashed and that will wreak havoc on cooling the rad? True? My fan spins freely right now with my hand, very freely. Is this a problem?


More gory details below for those needing more back ground.

I love this forum. New to it. I love my new (older) Supra.
I have a 130K Supra that sat in a barn mostly for 5 years - never registered or insured. It was allegedly driven 'often' up and down a private road to keep her moving by previous owner. Not too sure about that but could have been. The batt from 2007 was still strong and holding a charge for months sitting when I trickle charged it so who knows, maybe they were.

I bought her and she sat for 10 months. I put her on the road 10 days ago. Aside from lack of power, and a very cranky spot at 48 to 53 mph in Over Drive at low rpms (the car would shake, jiggle and wiggle - I thought it was just a loose frame feel due to the Targa but realized later that was not it). I've always been a hard top guy (sadly) until I got her. But the shake disappears at high and low speeds and higher revs on the motor in that bad zone.

Anyway, the car drove pretty smooth at 80mph, even had it up to 100. Drove her gently though about 500 miles, no trouble except for belching out PS fluid.

She started fine every time for a week. Drove her on hwy 60 miles at speed to work and then drove back 10 miles at speed. Next day battery is dead and not even close to enough juice to start. (Batt or Alt - will solve that later).

After a jump, she was extra low powered and cranky, on Hwy a few miles and then stupid stop n go rush hr BS at 6am. Maybe 70 degrees temp out (NE region). After running really poorly, I reved the motor to change the low rpms to 4k or maybe 4.5K or so. Within seconds I smell coolant. Then burning coolant. Within 2 minutes my car temp is almost at the red (she always ran at 35-40% on gauge the whole prior week). I panic and exit hwy, sit through two stupid lights and ditch her in city garage for 2 days while I work and before I can get my hands back on her. Dry radiator, put in a gallon of mixed ethylene glycol coolant and distilled, and limp her (with another jump) out of garage and 10 miles north in city. Get lost, drive around at city speeds with traffic lights in a full panic at this point. Finally get on hwy after 25 minutes (with heater on full blast in case this whole drive), and then after 2 miles at 70mph she overheats again. This time after pulling off hwy (within 60 seconds I shut her down) I finally notice a trail of coolant. Cool her off 1 hr, refill another gallon and drive her 4 miles to family member house (thank goodness the lived there), and shut her down, like a poor beached whale. She's angry and spitting coolant all over the ground.
Heavy drips / pour from two small gauge lines. Not the steel parts, the clamped flexible hose parts.
