Default Problem Adding Coolant, First Timer

Changed my coolant this weekend. It is finally done and everything is fine now, but what a pain adding the coolant. I just read this morning and it sounds like adding the coolant is a slow process.

I added fluid to reserve bottle, and could not barely get any coolant to fill the radiator. It would just fill the bottle. If I added any, it would run out the overflow. I took off the return line, burped the radiator lines, and barely got any in. I started the car with cap off to see if it would draw any in, and watched the bottle and my coolant temp. Temp, went to 180 fast, 190, 200, 220, I shut it off fast. Tried adding more, got very little in. Put cap on, ran car, went from 170 to 210 fast, shut it off. removed cap, and squeezed the radiator line until I coud feel it get hot and start burping bubbles out of the bottle.

I guess the key is to add really slooooow. I hate that the temps shot up to 220 so fast when I was adding coolant. Any problems with that happening??? I shut it down right away, but hate that I didn't get more in before starting the car. Once I got it burped, everything was back to normal.

There's got to be a better way, I just responded to keep your thread going.
I wouldn't keep doing that with no coolent, wait for someone to answer.

Easy way is find that T fitting in the middle that connects to your resivour. Fill up the rez and close the cap and blow into the end that connects to your rez until antifreeze burbles out of the T.

You'll need to fill the rez 3 or 4 times during this and you should be good. I put a bottle over the T fitting so the antifreeze that burbles out went into it and didn't make a mess.

Don't use high pressure (blowing is just fine, but don't use a compressor or something) and don't let the rez go dry. Super easy.

just start the car, let it run until t-stat opens, then slowly add fluid. It's that easy

Heck, sometimes I think I can make making a PB&J sandwich difficult.

I was just worried that I ran it with little to nothing in the radiator, and you are right, once the thermostat opened up when it got hot, it was easier to go in.

For future reference, undo the hose that connects the metal crossover tube to the radiator and fill the reservoir until you get coolant to come out of the metal tube. This allows trapped air to escape faster from the block.

BTW, don't sweat the 220* car will run fine at 230* if needed

This is the way I did mine and it worked great.
