Coolant

So where's the best place price wise to pick up 3 gals of toyota coolant.need to replace a gasket on inlet housing on my sequioa. Would prefer the red long life.

 

At you're local Toyota dealership.

 

Last time I flushed my system I bought 2 gallons of Aisin coolant (the red coolant) at O'Reillys.

 

I recommend your YouTube channel to some folks on the 1st gen Facebook page.

 

A lot of the aftermarket brands are premixed 50/50 with distilled water, so I'm not sure how you get to 50/50 after flushing with water since there will be a quart or two of water left in the engine and heater core after the flush.

The only aftermarket brand I found formulated for Toyotas that was concentrated was the OEM brand Red Concentrate at Pepboys. O'Reilly and the other stores only had 50/50 premixed (like Zerex).

You can find Toyota brand online (Amazon or ebay), but the local dealer might be more convenient.

 

You can use the green stuff from Prestone without any problems. Just add one full jug of undistilled coolant, then fill the empty container with water and add that.Siphon out the coolant in the overflow tank and fill it first. It will rinse out the antifreeze & give a near 50/50 mixture. Even with water let in the block after flushing.
Start the engine with the radiator cap off. Warm it up to normal. Gently squeeze the upper hose to see it's full. Rev the engine slightly and coolant level should drop. Add more water with engine reved. Put on radiator cap.
Check coolant level next time the engine is cold.

 

I've always taken the overflow bottle off to empty it. Just a couple of 10mm's on every one I've came across.

One trick if the bottle is negleted looking is to put a cup of pebbles in it with a few cups of water/soap and shake the hell out of it. Rinse repeat as needed.

I use green also, it doesn't last as long and there used to be a rumor (?,truth) that changing ANY antifreeze (more so the old green though) more than necessary in an alum. engine leached alum. from passages to the point you thin out the metal. I dunno, I've never had a block destroyed from it but won't discount it. Anyway, now that all my vehicles are Toyo. I'll go back to red because i don't feel like changing every couple of years anymore.
