Civic Si radiator
So I am planning on upgrading my cooling system.. and I was wondering if a full size radiator that is meant for Integra could replace my 2000 Civic si radiator with perfect fitment.

No, not without cutting the lower mounts off, moving them and then welding them back in. and then fabbing up an upper bracket.
I have to ask though, why? Stock half rad works fine, even a 500hp turbo civic will run just fine with a half sized rad.

Re: Civic Si radiator
Example, driving around town I can feel the clutch pedal getting warmer, and the engine bay would feel really hot, and once the clutch is hot the car hesitates to accelerate.
(The hesitation to accelerate and warm clutch may be off topic and has nothing to do with heat but I just feel its better to upgrade the cooling system.

Re: Civic Si radiator
You should probably figure out why it's getting hot (hint, it's not an undersized rad) stock rad may be clogged though, heater core could also be plugged or partially plugged. Engine may also be running overly lean (although normally there would be other symptoms besides the heat)

I have an aftermarket half rad, slimfan and shroud. It was 109 degrees here yesterday and on a turbocharged car it was more than capable of keeping temps normal.

On a side note, could a bad water pump cause heat problem?
(I am about to get my timing belt replaced along with water pump)
What aftermarket radiator? Out here in Los Angeles there are shops offering a half size full aluminum radiator for $65, and i was thinking its too good to be true it must be a knock off company.

Re: Civic Si radiator
As far as the water pump goes, depending on how it's failing, yes it could.

Yeah in a week or two, I plan on taking care of my 140k maintenance, and hopefully it will fix the heat problem.

Re: Civic Si radiator
Coolant is supposed to flow through the heater core. If coolant doesn't flow through the heater core, the engine doesn't get the proper flow of coolant to stay cool, and thus causes overheating.

Re: Civic Si radiator
Ahh i see, so can you can elaborate on the location of the heater core? I have tried googling but it only shows up topics of people with heat problems.

Re: Civic Si radiator
The heater core is on the passenger side, between the dash and firewall. Get a factory service manual, and either a Haynes or Bentley manual for your car. It'll make your life a lot easier.

Re: Civic Si radiator
OK, lets take a step back. is the engine even actually overheating? is the gauge on your dash reading above half? if not then i dont see any reason to touch the cooling system
lets think logically. why would a warm clutch pedal be any indication that you need a new radiator??
also, forget about the heater core. if there was a problem, it would be leaking or your heat wouldnt work.

Re: Civic Si radiator
Thank you for your answer.
The reasoning is because I feel like the engine gets hot really fast.
Example, driving around town I can feel the clutch pedal getting warmer, and the engine bay would feel really hot, and once the clutch is hot the car hesitates to accelerate.
(The hesitation to accelerate and warm clutch may be off topic and has nothing to do with heat but I just feel its better to upgrade the cooling system)

But as I said before, I would feel safer upgrading the cooling system altogether.
