Silly manifold hose


Recommended Posts

I need to replace the small coolant hose running from under the manifold to the t-stat housing. :cornfuzz: Do I need to get OEM or will something else work? And if something else, what?

 

Thanks,

Jay

My NAPA/Gates book sez in bold letters:

 

Do not use fuel hose for pressure-side hose on fuel injected engines OR ON COOLANT SYSTEM APPLICATIONS.

 

Buy heater hose - it's available down to 1/4" (not sure what size that hose is) and its cheaper than fuel line!

 

The difference is the rubber in heater hose is resistant to electrochemical breakdown which is caused by the cooling system.

Yo Arch -

 

Just reading the manufacturer's book, man. If you like coolant hoses blowing at inopportune times, go right ahead and put whatever the f:Dk you want on your vehicle.

 

I DEFINITELY agree that in a pinch, you should put on whatever you can, aldoat, but later, you should put on the RIGHT stuff. Ask your parts store to order it if they don't have it!

i gotta tell napa my hatchbacks are brats, just so i can get the right parts, so i dont put much stock in what napa says.

 

something tells me fuel line, especially efi fuel line, would stand up to heat and 14lbs. just saying, its not that complicated, as long as its black it will last at least 2 years. nothing against partsguy, just napa.

I stick with OE hoses. The most important fact for me is that they are molded in THE RIGHT SHAPE.

 

Standard hoses will tend to kink where you bend them and impeed the flow. At high enough flow rates, the kinks may also cause enough turbulence to create bubbles, and subsequent cavitation in the water pump. But that is extreme, and probably not relevant in car engines. I just like the word cavitation :D

this is a pretty funny topic.

 

the silicone is what im taliking about. it was orange stuff from napa. split down the middle as i sliped it on a nipple, then i cut the end off and tried again. dunno what happened.

maybe it was a bad batch, or it was cured too fast or someting

Well I got some sort of hose from........Napa and it was black. It looks to be a lot better hose than the one coming off the car, disreguarding the small split in the old one.

 

On a more helpful note, I remember someone bending a hemostat to actuate the spring clamp that hold it on under the manifold. I did this and still couldn't get the spring clamp to go on so I used a zip tie. It hasn't leaked yet (one day and counting).

 

So what other tricks do you guys use to clamp that hose w/o taking off the intake?

 

Thanks,

Jay

use a pair of pliers or just a screwdriver type camp. a lot of times i have kept the same hoses for swaps. the only brittle hose i saw was an RX, and i dont think it was the oe hose.

 

if you were the one who serviced the hose, then you would know what to expect. so then you dont have to worry about hings, since you know whats up about it

Jay, the hemo's were a Bill Putney trick. He was the man, haven't seen from him in a while.

On your zip tie trick, I would be a bit worried after it's been on there a while and maybe the system gets a bit hot and the pressure builds and thats a bad time to have a hose come off.

Can't you get a worm style clamp on there, and tighten it with a 1/4" socket? Your call, I have seen zip ties get brittle with heat
