Hey everyone-

Well, I discovered the source of why my thermostat was acting like the system was not properly bled... The top plastic radiator cap for the OEM radiator has cracked (not low enough to generate a pool/puddle, though).

I am now going to go Koyo + FAL fans (need to retain OEM radiator + fan thickness, as my IC pipe is RIGHT there now). I think the Koyo + FAL combo is actually slightly thinner than OEM (stock fan housings are thick as hell).

Here are some pics of the crack:




Has anyone else cracked their OEM radiator? I have not read a single thread on it since I started researching FI 2+ years ago....

Later!

yes , with Fal fan is thinner, with oem fan + the koyo = amost 1.5x of the size of current setup. stock fan is HuGe.

 

thats my setup now, a koyo rad and FAL fan

Could I possibly get a measurement from the OEM mounting bracket (where the radiator bolts in up top) to the back of the fans? I am looking for linear depth from that fixed point.

Just confirming it will fit. If not, customization time!

FAL fans already ordered. Waiting to hear back from forum sponsors on the Koyo.

ug, man s2000 needs some engineer time.. my rad just cracked as well.. same exact crack

 

Radiators on all models (Civic, Accord, RL, Integra, etc.) crack and leak at about the 10 year mark. Some last 12 yrs. some only 8 yrs. but 10 is the average. And it is not only Hondas. Toyotas, Nissans, Mazdas, etc. do the same thing. The tanks are constantly expanding and contracting during heat cycling. They become brittle with time and eventually crack.

 

mine cracked at about 56K miles

 

my s2k rad is doing fine, but in my 98 integra the rad cracked in that same spot.

jwa4378, How did you fix the issue with the blown head gasket? I lost track of that thread.

 

man ap1 fail with the radiator... lol sucks sorry
