1990 acty bleed screws

**RuzzP** · 12-16-2008, 02:33 PM

Hi all, we have been having some -30 temperatures and the other morning I started er up and in about 5 minutes I was up to normal operatin temperature(definatly wouldn't warm up that fast normally). No hot air blowing from any vents. I took er around the block and the temp gauge maxed right out but still no heat. Called my dealer and they figure its an airlock, I found 2 bleed screws on the block. They said there is 2 upfront near the heater core. Does anybody know where to locate these?
Any input is appreciated.

Here's a c/p from a post that looks helpful:

Standard fuel in Japan is 100 Octane......so use 91 all the time.

Fuse block is under the steering wheel.

Use a funnel with a 12 inch piece of hose to top off the rad. It helps to remove the storage shelf which is screwed on with 4 fasteners.

The AC rad and the engine rad do not share any fluids, only the cool air that passes through both. The overflow bottle is for the engine rad only. The Honda has 2 bleed screws on top of the engine that need to be cracked to release the air if you plan on flushing the coolant. Ohterwise she will overheat immediately.

Feel free to search through this website to answer all these questions and more.

Yeah I've read that, I think those are the screws I found, I'm going to go try shortly and see what happens

On my 1998 ACTY there are two bleeder screws on the steel tubes that run along the left underside of the truck. they are on the top of the tubes and hard to see. They are often rusted up pretty good so be careful not to put too much force on them. There're packing washers that seal the screws that are supposed to be replaced when you bleed the system.

It helps if you remove the spare tire; still hard to see, but at least you can get at them.

Well I have tried all the screws, 3 out of 4 are sprayin coolant good but the one on drivers side of the engine won't fully bleed, guess I'm gonna have to pull the heater core and see if its plugged up
