Hi guys,
Hopefully someone can explain this noise I am hearing on a Rodeo 3lt intercooled turbo diesel. After it is turned off and keys taken out, a noise like pressure releasing happens about 5 or so minutes after being turned off.

This noise continues to happen randomly. Any ideas? Is it something to do with the intercooler??? Is it normal? Maybe theres a cat or something stuck in there??

Thanks in advance.

NIck

well isuzu rodeo diesel!
first thing is there anything else going on with the vehicle?
next what type of cooler is it is it air to air
air to coolant?
but in either case it sounds like nothing most likely as vaccum canister bleeding
off or tubo spining down or the fuel system bleeding off. all of which sound normal
to me. although i am exactly on the opsite side of the planet from you with out really seeing the vehicle can't tell you for sure.
if the coolant is full, no other problem are present i would worry about it to much
if it seems to be a problem you may need to get a second opinion

Hi americanguy,

The Holden Rodeo equates to an Isuzu pickup in the US.

The Isuzu Rodeo in the US equals Holden Frontera in Australia.

they are all owned by Genral Motors right?
you see just tring to get these right
ok here's a question
if this is made over seas why don't they just change the name completely
instead of recyleing the names?

Why do they recycle names? Some marketing people must think it's a good idea.

Not all get recycled. For example Isuzu Trooper in the US equals Isuzu Bighorn in Japan and is Holden Jackaroo in Australia.

Hi Nicko,
I have a 98 t/d and it has done it from new .I think it is diff breathers or fuel tank pressure relief ,after the hot fuel has been returned to tank from engine , not sure ,but i can say its not serious 120000 km later still going ?
my two bobs worth.

Good to hear Darryl.
It runs really well, I just thought it odd that this noise keeps happening. Even an hour or so after turning off.

Thanks

Have you had your A/C on?

If so, then as the refridgerent cools, it can make a wooshing noise.

it sounds like it comes from the rear area of ute , it is definately something to do with pressure relief as it cools off. I would not be worried about it.

Well mine does exactly the same thing too (2002 Rodeo 3L T/D) but I thought I was imagining it. My theory (wrong or right ) is that it may have something to do with fuel pressure in the tank ? I thought next time I took the car in for a service I would mention it but then again the mechanics would probably prescribe some medication for me!! Happy noise hunting! Mark.
