My coolant just splashed underneath the car after a few minutes I shut down the car. The hose got loose at the top neck (plastic) when it got broken. Maybe an old crack when the hose was replaced.

Do I replace it with stock or a thicker aluminum upgrade? With the thicker upgrade, will the cooling fan frame directly fit in? Any other fitment issues?

Thanks.

 

I'm assuming you still have the stock radiator, with the plastic end-tanks. Get an aftermarket all-aluminum radiator, most here go Fluidyne or Koyo, but there is also PWR and some others. Do a search under those names for issues regarding installation and fitment. Basically, there are no guarantees of anything being a "drop-in". Still, this is a very worthwhile mod and not difficult. Here's something I posted a few weeks ago but search for others, there is alot of info. available.
Good luck.

Actually there is such a thing as a drop in radiator (exact replacement for factory) with out the plastic end tanks.

 

Are you refering to these radiators? http://www.radiatorworld.com/radiato...px?carno=15108

With Fluidyne or Koyo, can the plastic frames of the cooling fans just screw in?

 

Get the $214 all aluminum rad you linked to. It's got aluminum end tanks (no cracking) and it's slightly thicker than stock (1-1/4" versus the stock 1-1/16"). It drops right in (fans bolt right up). No fitment issues like the Koyo and not high-priced like the Fluidyne.

 

Just ordered it online. $214 Shipped!

 

Yea that's them. Take your pick the brass or aluminum. The others aren't that bad (I have a Koyo) and two of my friends went with the Fluidyne. But these are supposed to no issues. Jack

 

for 1/2 price it ain't too bad!
