Exactly everyone isnt a mechanic, so why do you speculate its over heating if you have no solid numbers to prove that it is?
So a gauge is a idiot light? Really?
Oh im sorry i actually like to know my engine temp, oil pressure, voltage and rpm.
you speculate that the engine is over heating because its getting hot? Hello there is combustion going on, the whole engine is going to be hot. Why keep guessing? You can pick up a mechanical temp gauge for cheap. Then you know exactly how hot the engine is getting. Why keep pussyfooting around? Buy a temp gauge, radiator, new fan clutch thermostat and water pump and be done.
Some things just cant be fixed as they arise. If you have issues in more than one place in the same system its kind of pointless on replacing one part and hoping its the fix.
Its like needing new brake pads and rotors and you only put new pads on it because you dont want to replace the rotors and wonder why it wont stop.
You can get a stock replacement radiator for under 300. New fan clutch 30-50, water pump less than 50. Thermostat less than 10 bucks, rad cap for less than 10. Used shroud for around 100.
So for around 500 dollars you can be done instead of guessing on what is wrong, you already know the whole system is wrong, leaking rad, no thermostat, possible bad clutch, no shroud.
Stay away from electric fan garbage.
Invest in redoing the cooling system not just replacing it with a junk setup.
Also for most instances i would advise not to buy engine critical parts off of ebay. There is a huge issue with inferior parts that claim to be name brand flooding the ebay market. Most of your standard replacement parts can be bought at your local parts store and most parts have a lifetime warranty.
If your going to buy name brand parts stick with summit, jegs or other reputable distributor of racing parts.
That link you posted is the wrong radiator anyway, that is for 69 and earlier where the water pump outlet is on the drivers side
Rad: $282

Fan clutch: $33

Water pump: $37

Rad cap: $6

Tstat: $6

Temp gauge: $17

So for around 380 dollars plus coolant and tax you can replace all the major components in the cooling system besides the shroud and install a temp gauge
No one is trying to give you a hard time but your not listening to the advice, these guys have many years expirience. Its like speculating you have no oil pressure but you dont have a oil pressure gauge, how do you know what is happening in the engine if you have no data on the cooling and oiling system!
