hey. I have a 1983 supra p-type. the other day it started leaking water from somewhere on the driver side of the engine. I've spent the last 2 days trying to trace it without dismantling that side of the engine. I cant see anything from above because the intake is in the way and I cant see anything from below because the suspension is in the way. there arent any water lines (from what I can see) where its leaking. does anyone know where it might be leaking from? any ideas would help at this point. I thought I was a good mechanic but apperently not good enough. :dumbass:

please & thanks

Search the term "suicide hose" on this site and you might find your answer. Welcome!

theres a coolant hose that runs along the underside of the intake manifold. a real pita to get to with the motor in the car and the intake on. theres also the iscv and the throttle body as well on the the drivers side, which have coolant flowing through them.

so I take it the only way to get to that hose without pulling the engine is to take off the intake? at least with a semi-limited tool box. with the iscv and the throttle body, if there isnt any cracks or anything could there be anything wrong with them other than a gasket? sorry if I sound like an idiot. I'm used to old chevy's

Yeah you have to take off the intake. Unless you don't have the A/C stuff there anymore, then you should be able to get to it without taking off the intake. Good luck.

Line up your cam timing/ignition timing and pull the distributor out.

If you want, you can eliminate the little hoses running through the throttle body and idle air control valve. I'm in Minnesota, have driven my car through winters and freezing cold, and never had a problem since I eliminated mine. Just used some short sections of hose, hose clamps, and silicone on the threads of bolts used as plugs for the short hoses.

Heck, after all that stuff is eliminated, is there any need for the suicide hose anymore? I'm considering eliminating that as well. The water pump provides hot water to the heater core, right?

well, if you have small hands, you can probably get to it without taking the intake manifold off. i know that i probably couldnt, so i replaced mine when i had the motor out of the car. the reason i mentioned the throttle body and iscv was to check those hoses for cracks or leaks first, since if they are leaking, they are alot easier to change then the suicide hose.

I think I'm just going to take it to a shop. knowing my luck I'll do something to it and it will never run agian. and that would be a real problem since it's my daily driver. I dont like shops but I guess you have to bite the bullet at some point :/

I dont think its shop worthy. For a lot less you could buy some strange tools and do it your self. Curled needle nose pliers helped on mine if I recall. I got a lot of funky tools, they come in handy for these cars. I would suggest finding your leak, or replacing the questionable hoses.

Look at the project and figure out what wacky tools would make it easier. Shop will likely pull off intake and charge ya an arm and a leg for it. It really isn't a quick task.

a friend of mine is going to come help me out with it. I guess back in the day he had the same car with the same problem. supposedly its a defect and he knows what it is already. I'll keep you guy posted. thanks for the help.

hmm. well at least you figured it out. and with a supra, i would not even bother taking it to the shop. this forum is better than any mechanic that might (and probably) rip you off.

every single thing i have done to my car which includes replacing the suicide hose, alternator, starter, every component of the brakes, and who knows what else, i have learned from this forum.

and idk about anyone else but when i replaced my suicide hose, i found it was easier to get to by taking off the starter. the nipple it goes on is just above it. a lot easier than the whole intake in my opinion. if you dont mind getting underneath the car.
