KA24 swap and the radiator

Post by oaklandsyd » 17 Mar 2009 01:09

SO..

I've been digging around prepping for a swap, and I'm trying to figure out the quirks before I get too deep and get stuck (which is inevitable anyway...). but all the information I run through keeps pointing to swapping the radiators out and installing electric fans.

first off, I have a Fiero radiator installed already. It's a cold maker. am i wrong to think it will work just fine??

secondly, why electric fans? if the fiero radiator is efficient, won't a shroud & pulley mounted fan work? or is it a matter of space between the KA and the radiator?

just trying to make a list and check things off. any help is nice.

It's just an issue of space. Assuming the Fiero fits and has appropriate inlet/outlet it will be fine....and fans rob HP too.

Why do you think it'll work just fine? Which radiator is it?

You won't have space for a clutch fan setup.

so I can probably assume that the fiero radiator and electric fans will probably hold up.?? its a slim radiator, efficient cooler. i'll deal with hoses when the time comes i guess.

a dip of a few HP isn't too big a deal, i'm just tired of L16's. I haul music gear around San Fran and it gets hairy when you're going up the hills with an extra 500+ pounds in the car... but i just really needed to know if the pulley & fan setup would fit or not. thanks!

I4, V6? Fiero came with different powerplants and, hence, came with different radiators. Is your radiator OE, aftermarket?

Hose inlet is in the wrong side for a KA swap. Rabbit radiator would be a better fit.

I've been running a ka24e for 3 "seasons" now, the rad application is from a 78-80 vw scirroco ( make sure its the one with the rad cap, later models used a overflow tanks with a seperate cap) Its been doing a fine cooling job I wired up the factory vw coolant temp switch via a relay to power up my electric cooling fan, its sits perfectly in the rad support using the vw rad "rubber cushions" and rubber insulated mounts to fasten the upper section... I think it cost me less than 200.00 for everything... The hoses line up perfect, the only issue I had was the "overflow" spout on the rad cap had to shortened slightly so that it didn't hit the rad support when I screwed it on.

bleeding the cooling system is a little trickier, I removed the coolant temp sensor and finished topping it up from there to remove an airlock...

In traffic, guage never goes above 1/2 and the cooling fan keeps operating temp consistent. :D

Clutch fan and shroud will not fit without major modification to either engine location or radiator location. KA24DE mounted with a reversed crossmember and stock 510 rubber isolators to 240sx mounts (typical KA swap). Radiator is a sciorroco/rabbit radiator without radiator cap (in-line cap makes bleeding easier).

Electric fans would be the only way to really go for this swap.
