    My radiator for my 84 Chevy K10 with the 305 is on its way out. Does anybody know of a radiator and electronic fan combo kit that will be a direct swap? I'm interested in getting rid of my stock cooler fan and going to an electronic one.

    I'm hoping that there's a kit that I can buy and it'll be a direct swap minus wiring up the fans of course. Hopefully one that won't break the bank.

    People here use Ford Windstar fan assemblies, IIRC. Someone had also done a really nice job with one that fit perfectly in the stock shroud. Maybe from a Taurus, but I can’t remember. It’s buried somewhere on here. Concerning the radiator, is it the Harrison brass-copper style, and does it just leak or cool below par? Reason I ask is that you could look into having it coded and have the leaks soldered. It’s generally happening where the tubes meet the tanks so you don’t have to worry about having solder slathered all over the fins in the middle and it looking trashy. If you’re concerned about the heat dissipation capacity of a cuprous radiator, which I wouldn’t be in half ton truck with a 305, you might look into a Champion all aluminum unit. That’d be the only new one I’d spend money on. IMO, Plastic tanked radiators are a manifestation of a huge cost cutting measure with mediocre durability. I don’t have a beef with aluminum, but if it’s a package deal with plastic, I’ll pass.

    I was looking at maybe something like this.

    Although I don't know anything about his unit. I was hoping there is a solution like this that doesn't involve a whole bunch of trial and error.

    I'm really wanting an all metal radiator. Right now mine is starting to leak at the inlets and outlets.

    I feel I should point out that aluminum is NOT a more efficient conductor of heat than copper/brass. In fact it is significantly worse.The lead solder used in the construction of a copper/brass radiator actually pulls down the efficiency enough that it is just barely better than aluminum. The reason race cars use aluminum rather than brass, is because the aluminum radiator can be 25% or more lighter than an equivalent brass radiator, and the durability and better cooling of a brass radiator isn't necessary in a vehicle that wont be sitting idling for long periods of time or throwing road debris into it. It will be far cheaper t ojust get your OEM radiator refinished. Find a local radiator shop and they can take it apart, strip and clean the whole thing and re-solder for less than the cost of that aluminum one you listed. I am upgrading my truck to the ford windstar fans when I swap to a MPFI 454. I got the full fan setup and wiring harness from a local junkyard for $40 and it is an exact size fit on my factory brass 4-core radiator. I can control both fans just like the factory trucks using the ECU from the engine I am swapping in, but you can also just buy a pre-made electric fan harness, controllers, and sensors for under $100 now also. If you want to read a little more on radiator material and design differences, this is a neat synopsis.

    agree with @Bextreme04. Didn't notice until looking closer that the link you put up is a radiator and fan shroud w/fans.
