dell... to remove the lower half of the air box is very easy and takes 10 seconds.

look inside and you will see 2 phillips screws...remive them both.

then the lower half slides up, there are concealed rails that it rides up on, and it just pops out.

to install, line up the 2 rails and slide nack down (slides about 1/2-1")
replace 2 screws and job done

edit: just realied ur not talking about the housing....ignore this post.. lol

this is mine...

yes...im glad i caught it but im not happy about it!
just ordered a new one, $94

iownme / Dell: To remove the thermostat housing from the engine block, space between the engine and radiator is tight, and the studs are at an odd angle, so this $20 articulated 3/8" socket wrench from Harbor Freight proved very useful. If you drive the front tires onto ramps, you can reached up from below, between the engine and radiator: https://www.harborfreight.com/t-bar-...het-98484.html

mine also came from sng barratt, $94 (ebay) with free shipping...i just mailed them so see about a member discount too.

ive replaced this before, dont remember how i approached it but i do have several different styles of offset/asjustable 3/8 and 1/4 socket wrenches

my last one was the same.
its outrageous these corps can sell DEFECTIVE products and walk away after the sale.
btw.. i made that vid

lower nut 13mm on 10\" extension with universal joint
so...both nuts were quite accessible, i used a 6 point 13mm socket, 3/8 universal joint, 10" and 15" 3/8 extensions, 3/8 rachet.
15" for upper nut and 10" for lower nut.

upper needed penetrating spray, lower didnt.
i suggest loosening both nuts about 4 turns and place ur collection pan underneath.
DO NOT loosten reservoir cap until its finished draining as it will gush out very fast and messy.
leaving it tight lets the coolant trickle out at a steady rate.
mine is currently draining and i'll continue in the morning

HOWZ THIS FOR WEIRD!!!!!
clearing out pics on my fone when i saw this pic that i took last year.

the same coolant line broke on my other jag ON THE SAME DAY AS MY CURRENT ONE exactly one yeat ago to the day.

hey dell, just pm'd you.
so i wish the job was as easy as it seemed.

i got it all apart and all back together in about 2 hrs with a long break.
tips:
first remove the rubber pipe where it attaches to the underside of the thermostat housing after you have drained the system. i finger tightened housing after draining to get better pulling power on the rubber pipe.

when you pull that pipe some more coolant wlll come out so have your container ready

next keep hose attached at the radiator (re-use it) and disconnect that hose at the right side of plastic T

on the left side of plastic T remove the metal circlip holding the 2 plastic pieces together (remember to remove the 8mm bolt) and then seperate the 2 pieces

now remove the 2x13mm nuts.

thermo housing will now come off the studs....you will HAVE to push the fans back like in the video to get the housing off of the upper stud... somewhat difficult but do-able.
(do this from under the car)

getting the new housing back in was a little difficult
get it roughly in place from under the car, in this position under the car i was not able to both push the fans and wiggle housing up and onto upper stud, so i went above the engine and was able to pull the housing up and fans back enough to get upper stud in the hole.

the rest of it was pretty straight forward.
except.... depending on where the tangs are on your pipe clamps, you may need a small set of vice grips to be able to access them.
whoever last worked on mine left the tangs in a very hard to reach position, when reinstalling the clamps, bear that in mind for the "next time"

THERMO....can you point me in the direction of the coolant burping procedure you recently posted.
thanks

didnt need burping.
filled to full level.
started car
put heat on max
as car warmed up fluid level went down so i topped up as it went down.
switched heat to floor/panel/defrost
added a little more coolant as needed.

( a little over a gallon of coolant came out of the car and thats about how much went back in.)

heat is working, temp gauge where it should be, fans kicked on when necessary.

car was running up on ramps for about 20 mins. no leaks.

for anyone else with a broken T piece.
you cannot buy just that piece. that piece is called the thermostat upper housing.
you have to order what is called the upper radiator hose with thermostat.
it comes pre-assembled and includes the upper and lower thermostat housing and new thermostat pre installed.

before you try to remove this assembly from the car
pull out this circlip with a small flat blade screwdriver and these parts will seperate.
its a tight fit so remove that 7mm pipe securing bolt first so the pipe can move a little.

someone thought you had good drugs and money being delivered.
alas all they found was a chunk o rubber n plastic (and cheap crappy plastic at that!)
