half size radiator.. what is needed to make it work...

i was look around. and i saw that senate had a half size radiator..
i asked him and he said there was some modifying to make it work.. but didnt really explain why type..

i figured it might not mount correctly.. (easy fix.)
and maybe the hoses might not reach.. (also easy fix with a trip to napa)

is there really anything else im missing....
(i am not a mechanic, so im sure im missing something..)

what is so different about mounting up a radiator for another car...

example being this one from mishimoto..
http://www.mishimoto.com/honda-civic...nce-92-00.html

even when i compare it to our stock radiator.. the inlets for the hoses are almost right, only the top one is off by a few inches....



maybe this is a question for my mechanic.. but its something i figured i could do in my back yard in just a few hours.. or does someone think theres alot more to modifing one then i do? (hoses might be off.. and mounting it... anything else?)

if its off by a little you can get a different radiator hose

Ok, you may have to fab up a bracket for it, find a way to mount a fan on it, and find hoses, or cut and piece some hoses together to use it.

Why would you want to reduce the cooling capacity of your car? I hope you live in a cold state! Otherwise you'll be overheating by the time you get to the end of your street.

you think incorrectly depsy! much dissapointment out of you! lol.. nah it would be mounted on the tranny side, to give more space for the turbo manifold and helping reduce heat retension in the motor from that radiator being so close to the turbo manifold

k bracket.. simple..
mounting a fan, mad easy with an aftermarket slimline fan(called zip ties, or whatever those zipper things are with the Flat ends on them)
hoses... only thing i thought might be hard. but im pretty sure the stock ones should work.

Thanks juan. i cant think of anything else

no you wont.. half size radiator that has twice the cooling rows and a larger core thickness.. it will cool just as well if not better then the stock radiator..
besides.. thats is way off topic, thats not what i was asking mcgarvey.



can anyone think of anything else i might be missing or might have to do that would be custom and might make this harder to do then it looks.

don't forget about the transmission oil cooler, unless manuals don't use the radiator for that. auto does though

just make sure that everything that ran to the old radiator gets ran to the knew one. You might have to redue some hoses

i think that that radiator doesn't have the transmission cooler built into it so you will need an aftermarket one

You're 100% correct with the overheating. The reason I switched to a half radiator was to accomodate my new turbo manifold and turbo. This summer I was running about 85% distilled water, 15% antifreeze and a half bottle of water wetter to keep my temps down. You lose the radiator surface area in front of the car that maximizes cooling in favor of saving space. Even though the core is thicker it doesn't help that much. I was seeing steady temps around 210*- 215* while driving. I added a reverse vent to my hood to allow for air to travel from the front, through the radiator and out the hood vent. Excess heat from the turbo manifold also leaves through the hood vent.

Also, in terms of heat dissipation, after the heat leaves the radiator it tends to stay under the hood of our Lancers and heats everything up nice and toasty. To combat this guys have switched over to vented hoods.

There are also alot of threads in here that talk about their engines overheating after adding the turbo. Most people chalk it up to having low coolant levels or air bubbles in the coolant system. The real reason is that our engine bays aren't really ready for the increase in underhood temps as-is.

In terms of my radiator setup, it was a radiator meant for a 92-00 Civic. The top neck needed to be swapped out for the correct size and the bottom neck needed to be moved to center and replaced with the correct size. You can just use standard aluminum tubing and bead roll the ends. As for the mounting, I used the existing bottom mount and had a rod welded to the bottom of the radiator to slide into the mount. When it was positioned at the proper height, it was marked and a washer was welded into place on the rod so that the radiator would sit at the proper height. The radiator was actually shorter that the stock one so it sits even at the top, but the bottom of the radiator is about 4-5 inches above the bottom mount. The top radiator bracket was moved a little to the center of the car to line up with the center post on the radiator. The top mount looks just as it would under the hood of a Civic, just on the driver's side instead of the passengers.

Cheers.
