Excellent work Deano....as ever another very usefully DIY from you !

Does this apply to 4200s and Gransports or just the 3200 models?

I am experiencing a coolant leak as well and my garage is requesting that I change the radiator (I have 47k miles on the clock).

Just 3200 JP, the 4200 is more of a traditional design. I would be interested if you can get the rad re cored instead of new, let us know how you get on.

Brilliant Stuff...!!!

CHaps
I have a suspect leaking radiator.
Is it an easy DIY at home task? I can spanner a bit

 

[rs48635]

Are there any other jobs to do "while you are in there"?

So far I will

Investigate and fix leaking radiator
change oil and filter
replace air filters
Inspect and replace any cracked or damaged turbo hoses
Have a good nosey around

Depending on your budget I would consider replacing the 6 coolant pipes with silicon (available from Roose Motorsport) and also the thermostat as this tend to stick either open or closed. With the rad out it makes getting to oil pressure sensor relatively easy - see my earlier post. I would also consider replacing radiator fan speed sensor as you will have to remove fan casing and again it is a lot easier to remove while it is out. (Even if you dont replace fan speed resistor I sugest you use opportunity to loosen the two screws while out as it will be a lot easier to replace insitu in the future when it does fail. All these items I have systematically replaced when they have failed but in hindsight I wish I had done them all together as they are all known weaknesses on cars with 70K on the clock. One point to check before you actually take radiator out is exactly where leak is as the cooling hose behind the alternator (and also A/C compressor) linking turbo to block also perishes due to heat and just requires short lengths of straight silicon pipe to replace. (also part of Roose cooling kit or sold separately I believe). All of the above I have done DIY.

I just completed this job a month ago and it is time consuming. As I had a full replacement rad I didn't bother having to do all the hoses too. The hard bit was getting the front grille and radiator brackets off.

If you do this I would consider getting a new condenser if yours like mine is shot!

 

[Parisien]

Yup...the power steering cooler gives bother too, good tip Phil

Luckily the cooler pipes were on mine so it was another job saved but one that I dreaded doing.

 

[rs48635]

uh-oh! sounds like a nest of vipers waiting to uncoil.
Does the grill and cowl need to come out? Only just had new one fitted after someone reversed into me - garage refused to replace my Rad when I pointed out the (old) leak.

 

[Contigo]

It is way better to do it on a ramp and exactly where I did it despite taking the rad out from the top of the car. You need to remove the Grille to access the Power steering cooler.

It's a bit of a job but with the instructions from Deano on page 2 it is pretty obvious. The fun you will have is getting the hex bolts off and some of them are a pig to access with the front bumper still in situ.

Just want to say thanks to Deano for this thread.

Noticed some steam coming out the front of my car the other day at work.. small puddle of water on the ground.. water level low.. hmm...

Yesterday took the rad out, replaced the 3 silicone pipes, back together.. today no steam or water loss. Win.

Was a very easy job to do, just time consuming as there is a lot to get out of the way. Took a couple hours to get everything out and didn't use a ramp.. all from the top. I must have been lucky as all my bolts and nuts came out easily and no "butchering" was required!

One question that I am not sure if it was answered here: How to get the cooler frame off the cooler?
It seems riveted together so just drill all rivets open?

Thanks!!

Indeed. That's all I did. They're very soft metal so even my old rubbish drills got through them with no problem!

Thank you very much for your fast reply
Now I can run this job! Mine was loosing a little bit after 67.000km. Could be seen from the blue crust. But since it won't get better through time, I rather do it now than never
Cheers!

So, done this job! Was quite tricky since there was almost no space for wider silicon hoses. The outer diameter of the silicon hoses was larger than from the original ones which resulted in the tendency to slip of the cooler. I had to cut away some outer part of the silicone in order to make space for the clamps. Only after I was 100% sure they won't go anywhere, I put the cooler back together.
After all I would next time find some smaller hoses. They could be 27mm instead of 28mm regarding the inner diameter.With 28mm they felt a bit loose.
So I would recommend this job only if necessary.

 

[Boomerang_GT]

After my overhaul with 3 new hoses, it is leaking again!
The 3 layer silicon hoses were to thick to correctly mount the clamps. Does anyone know which hoses to mount that leave more space for the clambs?
Thanks!

 

[Boomerang_GT]

Hello! Could anyone kindly recommend me some thin coolant hoses? Mine were 28mm inside diameter and 4,5 mm thick walls with 4 plies. So in total 37mm outside diameter.
This is too thick so safely fit the clamps. They slipped off the tubes and caused the cooler to leak for the 3rd time.
Thanks!

Couldn't (shouldn't) you just buy some bigger clamps?
