  1. I'll be swapping my leaking original radiator out for a shiny new Champion 2 row aluminum radiator (EC634) first thing tomorrow and I realized I don't have a drop of extra coolant around. Does anyone know from experience that this radiator will require more coolant than the stock radiator holds? Its odd I can't seem to find that info anywhere. Assuming I don't lose a drop of the almost new coolant while draining/refilling, should I 'make a trip to town' tonight to buy a jug so I'll have enough to finish the job tomorrow?
  2. I just bought some new headers for my 1974 260z, but they run into some transmission coolant lines. Does anyone know if I would be able to bypass these lines? Or what I could do to get around this problem? It's an automatic and I have removed the air conditioning. Any information would be greatly appreciated. The two horizontal lines in the second picture are what I am talking about.
  3. My 78 is getting too hot. I've done a few things to it since it was on the road, so keep in mind that I'm unable to drive it right now, only idle it when backed out of my basement garage. Here's what's been done to it since I drove it a few years ago that relate to the cooling system: -Deleted the coolant bypass line just to tidy up the engine bay. I plugged the thermostat housing and plugged the small coolant line that comes off the heater hose hard line by the #1 spark plug. -Tested the 180* thermostat in boiling water and drilled out the tiny bypass hole in the thermosta
  4. I recently picked up a 240z from an old guy that's had it for decades. It's in really great shape but hasn't been driven in awhile. I changed th oil when I got it home and have put a couple hundred miles on it. I noticed that it's leaking coolant in several places, one spot seems to be coming from where the head and block meet but definitely from a couple of the hoses. I started draining the coolant to flush it and found it to be very milky. I've attached a pic. It's not smoking or overheating so if there is something going on with the head gasket it doesn't appear to be severe yet. Any
  5. Hi. My name is Arnoldo, I'm from south of Mexico. I own a 1977 280z that will be in a future restauration process (as soon as I have enough cash). Recently I noted a leakage in the coolant tubes on the engine block, and in the one in the thermostat housing, so I purchased new ones to replace those. The problem came when I actually tried to replace them: I found that my car had an extra line that came out of the tube on the front of the block and to a part that sits on the upper side of the intake manifold, that has a lot of what I think are vaccum lines to different parts of the car, and
  6. Hi all, I bought a 1975 280Z in January and haven't felt like working on it till now mostly cause it is in good running order. A few months ago after taking it out and coming back i notice a growing pool of coolant underneath the transmission. So the search began, I read the service manual I searched the forums and low and behold I found nothing that was useful. Well I finally used my camera and took a picture of the mystery hose that is pissing away all of the coolant in my car. Can anyone tell me what it is where its coming from and what it should be connected to? Thanks
  7. I'm a new owner of a '71 240Z; I've posted on here a couple of times. While the car was in the process of restoration by the previous owner there were periods of long sitting and I am getting everything up to snuff. To help others help me here's what I've done so far: - Rebuilt transmission with new gaskets, bearings, synchronizer rings, and oil seals. Temporarily refilled with synthetic 75W-90 GL-5 (ouch; I know now), now has Red Line MT90. - Replaced clutch friction disc, pressure plate, throwout bearing, and slave cylinder - Replaced distributor cap, rotor, O-ring, breaker points, condenser
  8. I recently replaced the radiator and added an overflow bottle in my '75 280z. After refilling the system with coolant, I took her for a test run to check for any leaks. The temp gauge was reading good - about 5/8ths...then the gauge dropped to the bottom of its range. I checked the connection on the temp sender and topped off the coolant and took her for another spin. Again the gauge was reading good then stopped working again. I let the system cool again and took off the radiator cap to add more coolant, but the coolant was at the top of the radiator. Would an air bubble in the thermost
  9. 1971 240 with SU's/header -- Coolant Water mist sprays out between my intake manifold and head -- Weird. A bit of acceleration and it becomes a little geyser. It is betwwen the number 4 exhaust and intake runners and has actually made a hole in my manifold gasket. Could it be a leak inside the intake manifold? There is a water passage there. Please help!!! Thanks!!!
