280z overheating


Recommended Posts

Bought the car not running thought it was a bad fuel pump replaced it still nothing found it was a fusable link that wasn't making contact fired right up drove it around for a bit seemed fine took it for a longer drive and died on the freeway. looked to have a bad alt which killed the batt also noticed the temp was kinda high so I decided to get a new alt belt water pump and thermostat. today I replaced all the parts and it doesn't seem to be circulating. I filled up the rad with coolant and started it let it idle for a bit and then it started sounding weird so I shut it off opened the rad and I couldn't see the coolant any more so I topped it of again and fired it back up let it idle for a bit more with the cap off and wasn't seeing movement so then I put the cap back on and let it idle for a bit longer I could feel the rear hose was way hot and the top and bottom hoses were warm by the engine but cold by the rad I'm very frustrated mainly cause I have three cars and none of them work so any help would be greatly appreciated thanks!

Cheap stamped waterpump impellers have been known to rot to nuns of nothingness in less than 6 months once the antifreeze goes acidic, or in straight water.

 

I never run a water pump in ANY Z-car that I didn't install myself after purchase.
