Well i was about to slap on my pi intake onto my explorer motor when i noticed it was hitting something and not slipping into place. i did replace 4 inches of heater hose seeing how the old one was gone and ripped. i also did swap over my water pump heater line from my 97 to this 04 block. is there something i did wrong? what do i have to do the the line to make the intake fit?

here is what i have done to the water pump line.....

Is that the explorer heater tube or the Tbird one? If it's the Tbird you need to use the explorer or it won't clear the PI manifold.

you need the pi coolant tube otherwise the bottom of the intake hits it,you can see in the front bottom of the intake that it has an indentation where the pi tube runs over to the drivers side of the valley and mounts to the drivers side head.

hmmmmm makes sense.

anyone got any pics of what the pi one looks like? its prolly still in the garage but maybe i can fab up a line if i cant find my pi one.

yup, all you need is the PI coolant tube....right after the water pump nipple, it makes a 90* bend, up towards the driver's side head, runs along next to the head down to the back, and makes another 90* right as the block/heads end, and ends up pointing towards the passenger side of the car.....from there just use some heater hose to get it to the heater core

well i rummaged through the garage and found the pi line. do i replace the hole assembly or can i just cut it to where it meets the end of the maifold and connect the cut pi line with the cut stock line?

heres a pic, im guessing the right side is the right angle to connect to the pump.

do i need to use all those lines in the pic? or just the line clearing the manifold?

 

[justin case]

im not sure about the hose when i did it i just bought a length of hose from ace hardware and used that,do you have the pi water pump nipple on there too or the old style one?

 

[Porkchop]

it is the explorer waterpump nipple with 4" long 3/4 heater hose connecting to the 97 tube.

btw whats the proper name for it? ive seen it been called 4 different things here now lol

if you cut the rear tube shorter be sure you flare the end before connecting to rubber hose. that's what i did on my pi intake swap on my npi motor.

sweet thanx guys

ok i get it!! i messed up!! lol geezzz

 

[Porkchop]

ok i got the pi line on now, but i was wondering if this setup will work. instead of using the stock line i just connected the pi line to a heaterhose connecting to the heatercore line. does it have to be connected to the left side or does it really matter? i just want it to work and be safe. the other heater line will go to the front coolant crossover. here is what i mean:

edit: also does the pi line just slip onto the waterpump nipple? i dont need any silicone or anything to connect it?

 

[Bangster]

That is what I did. I used a brass Tee so I could put the coolant temp sensor that shuts off the climate control fan (freakin blower motor) under 100 degrees water temp. BUT I kept the inlet and outlet of the heater core connected to the same place, I didn't swap them around which is what you did I guess.

 

[Porkchop]

but my line is connected to the hose on the right and not the left, is that ok? and for that sensor can i just connect it to the extra hose coming off the pi line?

 

[Bangster]

I edited my post, I didn't set it up that way, I just added a little extra hose and went to the far side behind the valve cover because of the wires going to the O2 sensor. Personally I would have done away with the blower motor lockout sensor or whatever it is called/considered if I would have had a plastic elbow like that instead of 22 dollars worth of ACE brass stuff (an exageration).

 

[Porkchop]

i have extra heaterhose in the garage, should i just extend it to the heater hose on the left? just dont want to mess up anything. as far as that sensor, there is a long long skinny heaterhose coming off the pi line so instead of just blocking it off im gonna connect it to the sensor i took off the stock line. you can see the small line in the 2nd pic of post 14

anything else i should know or doing wrong?

 

[Bangster]

I don't know if you can do it that way, reversing the inlet and outlet or not.

The metal tube slips on over the nipple and is secured to the back of the head (yours seems to bolt to the passenger side with that long bracket, mine bolted to the back of the drivers side and the bracket is only about an inch long).

 

[Porkchop]

alright well i have extra heater hose so ill just go the stock design and switch the line over to the left side. the inlet is on the left.
