Supra Snake Hissing

[907mge]

I was doing the same thing before I did the headgasket. The little leak here and there gets annoying. Now after doing everything at the same time, it starts up quick and doesn't leak anything and it runs smooth and won't overheat. Personally I like the fact that it is a reliable car that I can start and drive off and not worry.

I will keep that in mind and check that Thanks, I think however at least my first attempt will be the main lower radiator hose. It feels a little like soft aerated foam past the clamp and after getting the new replacement hose for $15 it is evident that the hose has swollen or stretched about 25% bigger to what it should be and is soft. The end of it is damp underneath though it is hard to tell cause after cool down no noise or leak was present and that area of the engine has oil build up from long time oil leaks that I just fixed. I will certainly inspect that hose you pointed out though. I'll let you guys know what I find. Check my post on AC conversion cause I am attempting my first evac and charge and wondering if I should go with the r-12 I have or the r134a conversion. I could use some advise. Thanks so much for the diagram. That helps.


UPDATE

REPLACED the lower radiator hose and it killed the snake all is well now... I wonder if this hose had been contributing to my overheating problem before?

my car seems to have a near identical problem as you described. It might be a little higher up in my engine. I have a full thread post here, and have not solved the problem yet. I am most likely replacing the upper 90 angle short hose just under the water housing / T Stat area. I hope it will solve my car hissing and blowing out 1 gallon of coolant in 10 minutes after overheating. I put in a brand new water pump (super super easy repair for anyone wondering - try this replacement on a damn Acura Integra that's never been changed or had it's timing belt replaced - the crank pulley bolt is impossible to remove - it's on at like 700 ft lbs from the factory).
and also a new T Stat, and both new gaskets, new alt belt and new A/C belt while I was at it hoping it would solve my leak which only leaks after I run the car 2000 rpms and above... It did not solve it, and I am scratching my head still... My lower hose is more or less as you described, a bit soft, foam corroded away near the clamp etc...

Here just put this in another post so its handy. The rusty pipe is were the 90 degree hose hooks to, you can see the hose under the pipe disconnected and sitting there. If I were you I would do what I did lol, replace the lower hose and the 90 degree at the same time since you have to take the same stuff apart to get to both. The 90 degree hose can be sourced from autozone or napa or anywhere just go in with the hose and tell them you want to see if they have anything that will match it in there hose section. Usually they just let me go back to the wall of hoses and match it myself because they dont want to. But should be able to match one for $15 at most, may have to cut it down from a longer one but not hard. I think I paid $7 for the one I got. Sorry didn't write down the part number. At some point you should just save up the money and replace every hose on the car, that is the best way to make it the most reliable and will only cost $100 or so for all of them. here is the pic

The part is: 16285 Toy part / Gates replacement part #18030.
I just got one at Robbins Auto Parts/ Federated Automotive for $7.39
I had to cut about a 1/2" - 3/4" off the long end to make it fit with a standard utility blade. It's a pretty good replacement part, very snug fitting.
