Radiator Recommendations

Hi guys. I have a 1988 Honda Prelude 4WS A/T. For the past month I have been constantly refilling the antifreeze. I have also noticed steam coming from the hood as well as bubbles coming through the cracks where the upper plastic radiator tank aligns with the frame of the car. I read a few threads in this forum about the plastic tank possibly blowing apart from the aluminum core and because of this I am in dire need of a recommendation for an affordable radiator. So far I have done some Googling and have come up with a few brands: Replacement, Silla, CSF, and Koyo (I dont think this is the performance brand). I have also been searching on ebay for radiators and they have quite a few radiators that are quite the steal. Please help point me in the right direction for a replacement radiator. I'm looking to spend no more than $100-150. Last but not least, should I also replace the upper and lower hoses along with the radiator cap? Thanks.

Try to find a replacement with metal end caps instead of plastic. It will last longer. As far as price goes, I bought one off ebay a few months ago for about $75 shipped. Just make sure to buy from a seller with lots of positive feedback if you buy from ebay. You don't need a performance radiator if you are stock.

You can't go wrong replacing your hoses if it's been five or more years since they were last replaced.

I swapped in mine a couple of months ago, with the KOYO C885 all copper core radiator (best OEM replacement). You will be hard pressed finding a new radiator with metal tanks now, I searched for months with no luck. I went with these guys for the radiator, shipped out fast and radiator fits perfect: http://cgi.ebay.com/ebaymotors/88-89...Q5fAccessories
I also replaced the upper and lower radiator hoses with the generic GATES molded hoses, and a STANT radiator cap from WALMART.

I'm assuming that is the real Koyo brand. I'm just curious because I saw an online selling Koyo Radiators and their logo looked different. For the Gates radiator hoses, did you use the fitted hoses or unniversal? Did the new radiator use the same size radiator cap as the original or is a different sized cap required? Thanks.

Yes, that is the real KOYO brand. Radiator came with KOYO warranty in a KOYO box that said MADE in INDONESIA, which according to KOYO's WEBSITE is where they are made. This isn't just an eBay company, they are quite large in SACRAMENTO. A customer service rep told me about how their prices are cheaper on eBay while I was asking questions via online chat, so I bought on eBay instead of their website http://www.go-part.com/.

I used the UPPER (21670) and LOWER (21671) Molded Coolant Hoses by GATES, fitted not universal. I bought them cheap on amazon.com and free shipping.

Yes, the radiator cap was exactly the same size. I like the STANT radiator cap, works great and is cheaply sold at WALMART.

Holy crap, you save $20 bucks getting the Gates hoses off Amazon. Thanks for the info, I went ahead and purchased the Koyo radiator from Ebay. Was your a 1-row or 2-row? Thanks.

I've come across that thread during my search. I've checked with NAPA online and couldn't find an all metal radiator.

Prelude of the Month
I noticed you said you have an auto. So, whatever you buy, make sure it has the fittings for the auto transmission cooler, or you'll need to add a seperate cooler for your tranny

Thanks for the replies. I've already ordered an OE replacement Koyo radiator off ebay along with Gates radiator hoses. So hopefully I should have the parts buy this weekend so I can swap them in.

It is a single core radiator, just like OEM. The dual core is overkill for a stock engine (more expensive as well), also would have fitment issues if using OEM fans. BTW: You might as well change out the thermostat for a new one. I would recommend the STANT premium thermostat 45868 (180) OE Temperature, coupled with a Genuine Honda thermostat gasket.

Those were the all metal MODINE radiators, haven't been sold there for years. Plus MODINE sold out to PROLIANCE and they only produce plastic tanks as well.

The KOYO C885 is actually specific for the AUTO, but manuals can use to. Seems most radiators now are made for automatics, which is fine b/c all you have to do is leave the caps on those connections for the automatic if you're manual.

Thanks for your help ZIPPY. With the help of my girlfriend's brother, I got the radiator and hoses installed today.
