ok just to clear up a few things, hopefully lsjwannab can give us an idea...

do the H/E bolt up to the crash bar? if so holes have to be drilled right?

and which nipple is in and which is out?

I know the inlet and outlet is supposed to be on the right and the drain should be on the bottom left, so looking at it from this angle is the top nipple the inlet and the bottom the outlet?

also would it be better to remove the stock H/E and just have the ottp h/e or is it better to combine the old one with the new one ? I saw two diff diagrams, one with both the h/e working together and one with just the ottp H/E... what is the best way to to use?

Also what are the four smaller brackets on the H/E is for? because my H/E only came with two bolts and those bolts look like they are for the larger brackets welded to the top of the H/E.

yes, crash bar.

yes, two bolts for the larger welded on brackets.

yes, you have it oriented correctly

yes, top is inlet

yes, bottom is outlet

Everything ex said

I would suggest removing the stock unit personally.

The 4 tabs come on the core unit so don't worry about those.

so we have to drill holes on the crash bar... are those two brackets enough support to hold that thing at high speeds and possibly hitting pot holes and what not?

i'm going to keep the stock unit on. but i'll have the coolant run through it first

Yes they do the job quite well :)

When i installed mine i removed the stocker so i could space everything out...better cooling IMO

No I took that shit out lol

cool me too than soon

nice!!

how did you guys bleed the system after installing this? I purchased one and plan to run it in line with the stock, but ive never done anything like this before.

Could i use the drain as a air bleeder if it was on the top???

I think it would bleed it self out eventually I had to add more coolant after my first drive with it installed.. that was after I bled it during installation.

Guess my question is...is it safe to just install it and hook it in with the stock H/E and be good?

thats how i did mine. Although i had to drill holes in my bumper. It had 2 holes already but they where 2 far apart so i had 2 drill some 2 match it up. i shoulda took some install pics. i did it last week. Next week ill be installing the stage 3 duel pass endplate when it comes in. Ill take some install pics with that.

yeah, going through the crash bar wsan't a concern to me..just hooking up the hoses heh. if yours turned out ok then...

Just read the comments in this thread and it should make things easier. Worked for me :p:

How do you bleed the system?

sub'd... mine is coming haha my temps sky rocket

Did any of you guys run opt b with the ott unit? If so where the hell does the .040 orifice with the brass fitting go? I bought the opt b kit from crate engine and its purge line do i rly have to drill through the ott h/e?

^^^^anyone know?

make sure you install this as far forward as you can. My OTTP H/E just rubbed a hole in my AC condenser.
