Thread: Coolant Recovery Tank Help

Yes, then feel free to use the garden hose to flush until it's clear, then don't worry about capturing it anymore. You can go the opposite way too, and do the same with the radiator and engine block. The thermostat housing has 2 10mm bolts. Be careful with them, if they're tough to remove, try using it a bit of force in the tightening direction, then go back to loosening. That usually breaks up rust or corrosion and you wont snap bolts off in the engine.

I think there was something linked to me about it before I did it, but I really just took it apart and figured it out for myself and decided how much of what could safely be cut. And yeah I like the free part as well lol. I knew an open cone would really only be an improvement in sound, so I knew I could do the same thing by gutting it and have it be free. It's much more throaty sounding now. And I swear it pulls a little harder now, but I don't see how it would make a noticeable difference. I did get gas shortly after, and put a new PCS in my trans so I bet thats what made the difference. The previous gas was like a month and a half old.

I'll try to find the post, or the pics of mine.

He did a pretty good job, he's got more pictures too. I have plenty to make a write-up too but they're not uploaded. There's a few things you have to know so you don't make a hole or something. In the one pic theres a little square left, thats to keep the PCM in place. In another theres like a half or quarter circle, that's because it's hollow and if you cut it all, you'll have a hole on the top. I considered cutting all of it, and gluing a flat piece of the plastic I cut, but decided it wasn't worth it.

You really want to remove the thermostat and flush with the hose. The purpose of a flush is to "flush" out contaminants as well as old coolant. It's also good to change the thermostat, especially if it's still original. If the water flow when flushing doesn't exceed the flow during engine operation, you're only removing the liquid in the system. Also, when done flushing the system better be 100% water, and the rest air. At that point, there should still be about 5 quarts of water in the system. Add about 6 quarts of pure antifreeze (NOT 50/50) and the rest can be filled with water. That will give the proper mix since the system capacity is about 12.5 quarts.

Yes. And yes that's normal, the rest was air. It will eventually be bled and will need more
