Question Stupid 80 questions

1. I need to add some AT fluid. Where do I do this and how do I tell when it's full? I searched both the FSM and Mud for this, but didn't find anything. (I need to add some because I installed a new radiator -- those fittings at the bottom of the radiator are from the AT, right?)

2. When I filled my radiator with new coolant (50/50 water/Toyota Red), I used about 2.5 gallons of mix. I was guessing that I would have used more. Does this sound about right? I guess the engine holds more than I thought it did and didn't drain out.

TIA!

Matt

fill through the dipstick tube. not sure where, but i'd guess there's a plug somewhere to check level

It's on the drivers side below the brake booster. I stick a funnel in and fill it that way.

Thats about right amount of the rad fluid. Make sure you put some in the overflow bottle and check it for the next few weeks.

The mighty 22R-E takes about 2 gallons total of coolant for flush-n-fill. Like Romer says, it'll burp over the next few drives so make sure to keep the overflow filled and don't forget to turn the heat to hot to burp the heater core, too.

this is the best tool for burping a cooling system. I refer to it as the "magic funnel" Should be able to find it at your local parts store and well worth the money. The funnel attaches to your radiator like a standard cap.

It allows you to fill the funnel 1/2 full while running the vehicle so as your cooling system burps coolant flows in without spilling. Then you stick the stopper in when done and remove the funnel. Pour extra into storage bottle.

correct.. thats the funnel we all use in the shops .. its a spill free funnel. that allows you to burp the cooling system in a matter of minutes insteas of days... as soon as the thermostat opens and you have the heater on you should be good to go in a matter of 10- 20 minutes. if you swing by the pepboys off qubec and c470 you can borrow mine.. when your done use the stoper to plug the coolent and transfer it to the over flow tank to top it off.. then reinstall your radiator cap.. if your system burps more air.. the air goes into your overflow tank.. and the hose will siphons coolent into your radiator.. so make sure your over flow is always full..

AT dipstick/fill tube is directly behind the oil dipstick/fill tube, below the manifold, a little lower, and both of mine have red tops (vs. yellow on the oil dipstick). Like Ken says get a long, very skinny, funnel and fill it real slow or it will just back up and spill everywhere (DAMHIK ).

As for how to tell when it is full...I've found this to work for me (and what I used after doing a drain and fill and tranny pan replacement). Park it on a level spot and check it cold. Make sure the level is at least to the cold line. Now you need to go drive and get the tranny up to operating temp. I.E. a quick trip around the block is not hot enough. Pull in the garage or level spot, and with the truck still running, check the level to see where the level is compared to the hot line. Add a little bit of fluid, shift through the gears, and recheck. Note how much the level rose vs. the amount put in and adjust. Keep repeating this until you get the right level and I'd recheck it after a couple days and again a week later. If the level is really low though you'll feel it in the tranny. Can't say this is the best menthod but it is what worked for me

As for the AT cooler lines. The AT cooler is on the DS front of the radiator...You can follow the lines coming from the tranny to the cooler. I might be mistaken but I don't think the AT lines go from the AT cooler to the radiator - I thought it was one hose coming into the cooler, and then one hose leaving going back to the tranny but maybe the hose leaving the AT cooler then also routes to the bottom of the radiator.


As for the radiator...When I did my coolant flush folks here said to refill when the front of the truck pointed up (i.e. like up the driveway) and refill slowly and that would help burp it...Never had a problem.

I'd suggest though after running the rig for a few days, use a coolant tester to check what mix you are really at. After my flush I was too high on the coolant even though I swore I mixed it 50/50. I could tell in my coolant temps that the mix was off because I was running 5-10F hotter than before. I gradually brought the split to 50/50 by dumping what mix was in the overflow container and dumping in 100% distilled water and then rechecking the mix % a few days later. Temps came right back to expected levels, even a little cooler with the right mix. Too much coolant = running hot.

Cool. Thanks, guys. I'll keep an eye on the coolant. Jeff, what do you use to test the mix?

The hoses on the bottom of the radiator are definitely A/T -- I just looked at the FSM.

I use one of those cheapy Prestone coolant testers...Not sure how accurate they really are but works for me...Feel free to stop by and borrow it

Not sure why Matt would need that. It's for testing to see if your coolant is still good and needs changing
