Defender Puma 2.2 intercooler hose to throttle body should be replaced

Finally found time to change out the turbo hoses.

I unbolted the water pump and swung it out of the way. One extra bolt after metal tube is unbolted Plenty of space as you can see in the pic. Even my old thin skin didnt let blood out!
The BAS hose kit mentions trimming the turbo end of the hose on RHD. I needed to trim about 12mm off both ends of the elbow under the thottle box to get it to fit without fouling engine mount bracket.

Thinking of changing my 8 year old Intercooler hoses before they let me down

reading this looks like the BAS kit of 3 hoses is the way to go

also thinking might be a good time to also upgrade the Intercooler ( BAS or Allisport ??……any comments which might be better ?

So as this is quite an expensive item my question is would it make a noticeable difference to the pick up of my 2.2 defender ? I find the pulling out into fast moving traffic and my lack of pick up in speed a tad disconcerting at times . That would be my only reason for making this expenditure.

Then don't bother as it wont make squat difference in (noticeable) performance.
Even running them on a Dyno, I cant see a difference, considering dyno readings will vary between EVERY engine and other variables such as temp, mileage, snorkel, tyre size etc.

The big improvement is:
*Tuning (pref on a dyno).
*doing a de-cat (for offroad use only)
[bighmmm]

*Eventually the 3 turbo hoses will fail, might as well fit silicone ones when they do.
*Eventually the intercooler will split, so a all alloy one will last.
*I've fitted dozens and dozens of the terrafirma hose kits and i've not had one fail.
*but I have had some of the brands listed here fail, so work that one out?

*TF742LATE is the (terrafirma) hose kit for a 2.2 Defender.
*The elbow on the plastic intake I still use a genuine one and typically replace them at 100K.

thanks for that ….some good food for thought

so why do people fit the larger Intercoolers if they make no difference to engine performance
……keep it cooler for towing ??

a all alloy one is a reliable replacement for a standard 2.2 that will fail eventually.

Long time lurker, first time poster here :) thought would add to your original post as i recently(last week) upgraded to a 170AB tune + BAS intercooler and BAS hose Kit and very happy with the results.

I particularly wanted to share my experience changing the 90 degree Elbow (lot of sweat, blood and skin lost in the process) which will benefit fellow 2.2 Puma owners.

I tried various ways but the one that worked for me did not require me to remove the water pump.

Here is what should work and can be done quiet quickly (mind you this took me a day to work out ;))

1. Remove the metal pipe connecting the return intercooler hose to the elbow connected to the throttle body by removing 2 10ml bolts. (loosen and slide back the hose clamps from the elbow and one from the return hose connecting the metal pipe)

2. Remove old Elbow (Once the pipe is removed you will have easy access to remove the elbow)

3. lightly grease the lip of the throttle body to help install the new hose along with clamp. please make sure the clamp is tight enough to secure hose in place, but not torque it up yet as you will need to align with the metal pipe. (In my case I also used my right hand through coolant pipework to position and push up the elbow into place.

4. lightly grease the lip of the metal pipe to be connected to the elbow.

5. Reinstall the metal pipe (might have to align with right hand and jiggle/push fit into elbow)

6. Secure pipe to water pump with bolts removed earlier.

Job Done!

Note: A long Flexible Socket 1/4" Extension will make the job a whole lot easier in my opinion

“”1. Remove the metal pipe connecting the return intercooler hose to the elbow connected to the throttle body by removing 2 10ml bolts. (loosen and slide back the hose clamps from the elbow and one from the return hose connecting the metal pipe)””

trying to work up the knowledge ( and courage) to do this hose change over

had a good look at the metal pipe that needs to be removed to get access to the elbow ….but I can only seem to be able to see one bolt holding it to the water pump …..where is the second 10 mm bolt hiding ?

It's there hiding under the water pump. I had the same question at first but it is there. If I recall correctly two of the three water pump securing bolts also hold the metal pipe in place.

This is a great photo Thanks

Now if I wanted to loosen up and pull back the water pump would I only have to undo 3 bolts …..or do I need to mess with the belt too

You need to slacken the belt tensioner and slip the belt off the pump, no need to remove it completely. Then same when you’re done to put it back on again.

You should be able to find some YouTube clips that demo it, pretty easy once you know how.

I did a quick video just for you lot [tonguewink]
