I'm sure this has been the bane of some of your guys' existence. The rear coolant hose coming from the rear of the top of our engines failed on me. It was too dark to see exactly what failed when it happened, but I think it split or got a cut in it. The thing is, I replaced that sucker about 2 months ago when I changed engines...wtf?! Is there a more permanant solution to this silly pipe?

Also, I limped the car home when this happened. I got a huge plume of smoke behind me, as well as a good smokeshow coming from the engine bay. The radiator was cold (it was about 10 deg. F outside), the coolant bottle lukewarm, the engine cam covers cold, but the temp gauge was skyrocketing towards "ohh sshhhitttt" range. Where is the temp gauge sending at anyway??

So, bottom line is, is it that common to blow that hose every few months?? Anybody got a good solution to it? Did I possibly screw my motor over? If so, It is SOOOO time for a 1J. Thanks.

I think somebody should fab-up some Stainless Steel braided lines for about every hose the 7mgte has. I know that the SS power-steering line is a big help.

My condolences to you. Get a stainless steel kit made up and tell us the specs:D . Best regards.

I hope that hose never blows on mine.. it looks like it would be a major PITA to change without pulling stuff off the engine. If your NA theres that little plug back there that can fail too. I had that one blow out on me when i still had my 86.5.

No engine can stand running without a cooling system, even if its short runs you are running a risk. at times is better to have it towed.

Is this the long hose that runs into the firewall or the small one that bends at 90 degrees? That small one is pure murder...

Anyway, I changed the small 90 degree one when it developed a leak. Two months later when doing my HG I took it off again to look at it and it had a tear developing, it would have not lasted much longer. I was like "what the heck why did this not last very long?"

The reason, as Madghost (Tyler) informed me, was that I cut my hose to size with a kitchen knife, and this was a very unsmooth cut, which probably left burrs which turned into tears. The solution was to cut the new hose down to size with a hose cutter, which uses a fairly blunt metal edge to make a much cleaner cut to the rubber.

All this is assuming that you are using an aftermarket hose which did need to be cut to size, not a stock hose which is already the perfect size.

It's a bitch. Mine blew, and it about to blow again.

I was keeping an eye on it to see why it was having problems, and I think I know why.....

It's friggin hot where its at, right above the engine and next to the turbo, held by a metal bracket, and then bent 90 degrees. The hose expands a little when it gets hot (as all materials do) and develops a kink, holding back hot coolant. This makes the hose swell, which isn't good for it. I think either taking out of the bracket or fabricating something to hold it a little higher and straighter would work....or the metal braided hose.
