ok, i need help =/
i tried to install my weapon r 4-2-1 header today, and failed horribly.
i took off my old aftermarket header, s-pipe, rad support bar, and fan shroud.
i tried to put it in from bottom up but the A/C lines are in the way.
because of that i took off the fan shroud because i read that it'll help installing it from the top. So, i tried installing from the top but it wont fit =/

any advice??

i have a 08 scion tc btw.

 

put it on a lift and put it on from the bottom, that's how i did mine i think. i installed it with the fans still on and it was a b to install but i think that's what worked for me if i remember right.

 

yeh, i tried to lift it from the bottom but the ac lines got in the way.

 

you have to come from the bottom. i never had any issue with the A/C lines, just the fan shroud

idk about 2008s tho

 

I was able to get mine in from the top. just angled it in and it fit right in. only thing i had to do was take out the radiator fan.. I'm not aware of any differences between 05-06 and 07+ that would affect the installation of the header.

 

thats so weird =/
lol, i tried it from the top it always seems to get caught on something =/
so i cant angle it the right way, even with the fan shroud on..
jeeze, i guess ill have better luck tomorrow.

 

when i did it i took off the two screws that hold the ac lines in and that should give you more space to get the header through the bottom

 

i installed mine from the bottom, i removed the fans and the oil dip stick tube i kept hitting on that.

 

If its an automatic it has to go in from the bottom. It takes a lil finagling to get it in but it goes. I helped my buddy do this on his automatic 08. Just remove the fans from the radiator, the oil dipstick tube. Watch out for the fins on the radiator though.
