Yes. Autozone sell a kit for about $10.00. I didn't mess with radiator neck.It'll work automatically.
Thanks. I be at AZ at 9:00 a.m tomorrow morning LOL, I built a "one & only" blown and injected 430 CI Lincoln powered AA/Fuel Coupe which everyone said "can't be done". I'll be dammned if this &*^%#@% Ranchero is gonna beat me
I have a bigblock chevy in a truck that would run hot on the highway and then would cool down when i got off the highway. What I found was that my shroud was to tight and would not let forced air on the highway pass throught. I redesigned the shroud so that I had about 5 inchs of rad top to bottom free of any obstructions.I also installed a remote trans cooler to keep any added heat from entering my cooling system.Hope this helped out !
I believe some GM vehicles,Vettes I think,had flaps built into the shroud.They would be*****ed shut by the fan at lower speeds.but on the hiway the airflow overpowered the fan and would open them so more air passed through the radiator.
My fe352 was the same way. I switched to electronic ignition, a flowcooler water pump, an electric fan mounted in front of the radiator that is temp controlled and a new overflow tank with a 180 degree thermastat. Now it runs at about 190 degrees constant, even in stop and go traffic.
OK guys, I'm back to working on the old Ranchero again after a few months off. 1) I had the radiator disasembled, tanked and rodded. It was clean as a whistle to start with, but I wanted to absolutely confirm that it could not be the problem. It is a four core large radiator and the guy said that it should cool any 390 engine. 2) After days of searching, I found a new lower radiator hose that fits and has the spring inside so it can't collapse. 3) I installed "another" 160 thermostat just to be sure. I drilled three small 1/8 holes at the outer edge to prevent air being trapped at fillup. 4) This Ranchero has a water/mud splash panel (1/16 steel) that fits on under the grill, from frame rail to frame rail and just below and in front of the radiator. It is supposed to stop water & mud from clogging the radiator fins. I drilled about 20 each 1 1/4 inch holes in it so air can pass through it to the lower portion of the radiator. 5) I removed the electric fan and put the 7 blade fan with clutch back on it. 6) I called Edelbrock, I have one of their 600 cfm carbs, to ask about running the vacuum advance on timed-ported or direct manifold vacuum. They said if it has electronic ignition, the cam is mild and with an uato*******, which it does, use the timed port. Mine was on the direct manifold vacuum port. I made the switch. I have started it up and it seems ok. It gets to about 180 and holds. But I have not yet driven it on the road and/or in traffic. That will come later. As to a shroud, none yet, but I will build one this coming week. Plus I plan on building a small (1 " x 36") air scoop that will fit just under, but behind the grill to scoop and direct air to the lower portion of the radiator through the holes I drilled. I will report the progress later.
