Oil Cooler hose exploded

travisjb · 03-08-2010, 11:26 AM

I was not able to confirm whether my issue was due to hose failure or installation failure, so that's going to remain a mystery...

as for abakja, the data we've collected suggests that AT cars have much less problem with overheating, so unless you are experiencing problems, I would hold off... ie are you regularly seeing temps above 280F? 260F? (EDIT: 2nd though, don't answer this here! we already have enough oil overheating threads, lol!)

Just to add a little light on my hose failure. I tied the hoses into the frame (using what GTM supplied) at the cooler on the left (passenger) side. I also used cinch straps to secure the hoses further against the front structure.

When removing the hoses I saw that the plastic on the passenger side (drill holes through the pieces for the hose to pass through) was in a different position than when I initially did the install so your theory on the hose movement is correct. The hose movement occurred on the other side of the left side cooler, (the small one beyond the hose clamps at the base) though, so I'm not sure how much tension actually got transmitted to the fittings at the oil cooler.

I was also wondering about the vibration of the mounting bracket and if the hose was fairly snug, the bracket movement might induce a load at the fittings as well.

The idea of having enough slack in the hoses seems like the way to do the install in order to accommodate for engine movement and general vibration.

I only see higher temps when I manual or paddle shift compared to normal "D" driving. Of course this would mean revving till I upshift or vice versa...

I think that members will start to leave a little more slack in the lines and lay off zip-tying the hoses together or to the frame as I dont see this totally necessary, but again Im going to keep an eye on the threads and change my oil next weekend and see what comes up after the next 3k miles...

When the op called us saying that one of the hoses we supplied with the oil cooler kit has burst, we assumed responsibly and send him a new hose with a return shipping label so we can get the hose back to inspect it . Upon inspecting the hose, we discovered that the hose has been shorten, we order thees lines pre-cut to an exact length. if you shorten the line and you don't have the experience required to reassemble this type of fittings, the line will com apart end of story . and this exactly what happened in the op's case .

The kit is specific to the 370z we don't offer any other kit for any other make, the few inches of extra length that the hoses comes with is to give flexibility to the installer so they can install the cooler anywhere they want and for the extra slack required with the engine torquing.

That explains a lot. Sounds like you did the right thing as a company too Sam. Not many companies in the aftermarket game will just give you new parts before inspection of quality failure. I would just like to point that out.

Sad. You hear cases of owners supposedly wronged by dealers, and look what we have here - a case of deception on the OP's part so he could get a new pair of hoses that he modified. Maybe not him, maybe someone he got to install the part, but none the less...its obvious GTM caught him red handed.

GTM - a lot of respect to you for standing by your product and shipping him some new hoses.

OP - wow. Jigs up, eh?

The even sadder part is that I was dupped into thinking that his other "used" line was unaltered and perfectly fine, and thus purchased the kit from him. This weekend, I will post pics of the un-install, while I await some new lines from GTM. Grrrrr....

Whoa whoa whoa...you bought some lines from him? Do you know if they were unaltered at all?

Man, that'd be scary...not even worth the gamble. Let me guess, he was all talky leading up to and including the sale, but he's gotten quiet since.

Kudos, GTM. Seeing how you handled this situation definitely earns some repsect for your business.

Something seemed like it was missing from the OP. A lie by exclusion, it seems to be.

I guess GTM is going to have to include a little warning in their packaging now, sort of like the "Don't use this in a bathtub" warning on new toasters.

TipsZ.....I posted a link to the assembly instructions for the Hoses in my DIY thread. I was gonna PM you on Sam's revelation, but seems you found it. Looks like you're getting new hoses? I'm sure it would prove interesting to disassemble to old ones, at least the suspected modified one and see how it compares to a correct assembly..
