Switching Radiator

[cja3rd1983]

I just bought a 1990 honda prelude si A/t :( but only has 127k i had a over heating problem and i changed the thermostat and that fixed it. But like all old cars when i went to place the upper hose back onto the radiator, part of the upper radiator broke off where the hose connects. Anyways the problem I am having is I never change one befor and i keep getting stuck on what bolts i need to take off to get the dern thing out of the car. I bought a new one as well as hoses, clamps, perfered fulids ( coolent as well as trans) new clamps. Everythiong but the heater core. Does anyone know a site that will give me step by step on how to do this.

i just did mine a couple months ago on my 89 si.... i would post some pics but that takes to long so ill give a quick instruction list

 

 

1: theirs 2 bolts holding the hood latch on(infront of the radiator) by the hood cable

2: theirs 4 bolts on each side holding the radiator trim bracket on you'll see the bolts about 6" away from your lights

3: you'll have to disconnect your fan (makes it easier to unbolt if you leave the fan on while you take the rad. out)

4: take off the bottom rad. hose

5: unscrew the trany cooler lines

6: pull the radiator out

 

 

 

i do believe all the bolts are going to be 10mm and the trans line is roughly a 10mm or 12mm....

P.S. its a pain is the a$$hole to get out kuz you have to twist it a bit and turn it diag. and all sorts of ways to get it out, but its a breeze to put back in. (just remember leave the fan on while you take out and put in the radiator) makes it a hell of allot easier to work with the fan that way.

ok wow are you fricken ferizzle right now's. you basically just tore apart your whole motor just to take the rad. out WOW!!!

 

 

and im prty sure he can figure out to move certain things aside to take it out kuz if your a retard and cant figure that out then you have no purpose being around a car at all nor able to drive 1.

 

kuz here is a basic pic of what should be done and its prty easy and ill even mark the areas for you that will have to taken apart witch is easy as turning a damn wrench....

 

 

 

 

green: upper and bottom rad. hose

red: overflow hose

white: tranny cooler lines

teal: hood latch mount bolts (4x)

orange: radiator trim piece/cover bolts (8x)

 

that is all your going to have to take off to get your rad. out that is it nothing else besides the fans but you can take em off when the rad. is out... if you cant unscrew the tranny lines with the fans on just take em off easy as taking a dump ok prty simple if you ask me.

 

not the best diagram but its the general idea that is intended there
