Coolant Flush

[LebaneseCam]

How can this be done with just me and my friend, any links or faqs would be perfect.

I just tried to do it on my 3VZFE and i botched it.

I found the drain for the radiator easy enough but the engine block drain plug eludes me. Where its supposed to be is on the rear bank but I just cant find it as there many things in the way, like the distributor, etc etc.

I got the car with green coolant, so I went to Toyota and bought a gallon of red coolant for about $16 and 2 gallons of distilled water for $2 from supermarket.

I ended up just draining the radiator, flushing what I could with tap, then added a gallon of distilled, ran the car, then I drained and filled with distilled and coolant.

Going to try again to find the damn drain tap and do it again.

Also ratio of coolant is notless than 50%but no more than 70%. Toyota says...

the problem Im facing now is getting into th engine as well, we are trying 2 get the theromstat forced open so it can get in the engine but no luck yet. This is getting really frustrating.

^ The thermostat won't open till the engine gets hot enough.

So just let it run till it gets hot.

The fan will kick on and the upper radiator hose will be hot.

Make sure the heater is turned on, otherwise you'll have old coolant left in the heater core.

1. Remove radiator cap and start the car. Let it warm up to normal operating temp, with the heater on.

2. Open the drain on the radiator (its on the lower left hand corner).

You'll want to have a water hose handy for this. You need to fill the radiator while its draining. Keep doing this till you get nothing, but clear water running out of the drain on the radiator.

3. Shut off the engine and let the remaining water in the radiator drain out.

Close the drain on the radiator.

4. Get a clean bucket and mix a gallon of antifreeze with a gallon of water (distilled water). This will give you a 50/50 mix.

Fill the radiator.

5. Remove and flush out the coolant overflow reservoir.

Reinstall and fill with the mixture you made in step #4.

6. Start the car and let it warm up to normal operating temp with the heater on.

7. As the engine runs air will get worked out of the cooling system. So you'll need to fill up the radiator as necessary (with the mixture you made in step #4).

8. Reinstall radiator cap.

what's up w/ the distilled water? is that necessary?

Its not necessary, but its better to use distilled water.

also would my local pep-boys have red coolant? or i have no choice to get it at the "stealership"?

One easy way to keep the thermo open, take it out. Bolt the neck back. It'll leak a bit but you'll be able to flush the engine. Remove top hose on engine size. Put garden hose in top hose and keep filling rad with water. Start the engine, turn on the heat and watch coolant come out from engine. Wait till it come out clear then stop engine. You should have most stuff come out this way.
Make sure you put thermo back.

If I take out the termo and bolt the neck back, do I still attach the lower radiator hose to the neck? And the part where you said remove top hose and fill with water, do I remove the top hose from the radiator or the engine? Sorry just a lil confused.

Engine.

amerikim, if you couldn't find your engine drain plug and you have a 5sfe, I could help you out. It took me a while but doing my own scouting, I found it on mine a while back.

What if your heater doesn't work? My system only runs cold air, the switch broke awhile back but I don't use the heater anyway... i'm in Florida.

probably not a bad idea to at least replace the lower radiator hose while doing this. i decided to replace both the upper and lower. however, probably the lower hose is more important. the lower hose is only $16( i forget the exact price of the upper hose, wasnt much...) from the dealer and you can grab the red coolant while your there. if the lower hose goes then you can kiss all ur new coolant goodbye... up to u though.
