I have a 89 CRX with a b16a in it and I think a stock radiator (I dont know because I bought the car like this) anyway it is overheating and I think I need a new radiator, will a Del Sol V-tech radiator fit if not what will?? The motor has multiple upgrades JG ported and polished heads JG cams JG throttle body and a DC sport header with greddy exhast I know with engine upgrades comes more problems,and I need to fix this one ASAP please HELP.

 

Are the fans coming on? I can't imagine a Radiator dying unless you damaged it some how.

 

I didn't damage it its just not working to full potential because I can't leave town without overheating. Its time for an upgrade. I turn the fan on manually, so yes it is working but I only have one of them, I don't know if there is room for two.

 

I mean maybe the Radiator is too small, but I doubt it since I heard the 88-91s had larger radiators than they really needed.

 

It could very well be a larger radiator, but regardless its still overheating and I was told that a dual core radiator would probably fix that problem. I just don't know if the del sol radiator would work or what one to put in it. I need help man???

 

I'm currently running my stock 90 si radiator and its cooling fine. You should check your thermostat and water pump. Also the del sol dohc vtec will not fit, its too tall . I tried the one way you can fit it is if you modify the crossmember which i thought wasn't worth it . On the other hand i have been told that you can use a 93 teg twin core radiator . Hope this helps, lata

 

definitely check your thermostat, water pump and thermostat relay...they cause lots of problems

 

i had the same prob about 2 months ago. I changed the thermostat, but when i tested the old one(put it in boiling water) it was fine. If the cap is bad the coolant doesnt flow through the rad. I bought a new rad cap and i think that was all the problem was. Try that before you go and waste money on a new rad.

 

Thanks for the info fellas. now, can I just go to my local Napa and get a new thermostat or do I need something special? Also should I take AC coil out that sits in front of the radiator

 

Does Coolant eventually loose the ability to keep the engine cool. Maybe you should drain and replace the coolant.
