I need to re-fill my coolant .... how and what? Help!

Jim_rx7 · May 02, 2007, 08:58:12 PM

When changing the oil cooler lines I had to pull the bottom radiator hose off because it was in the way.

I pulled it off and them unscrewed the rad cap so the system emptied itself. (there\'s still a little in the rad tho, as I can see it at the bottom connector).

Now, Obviously I now need to flush the remainder and re-fill the system.

I have searched etc, but I couldn\'t find an idiots guide, and when it comes to this stuff I am an idiot! .... lol.

I need to know what to do now (to flush the rest), then what to do to fill it up again. Also, what I can use to do it.

What coolant, what mixture of coolant/water etc?

This may have been posted a million times, if so.. I\'m sorry. But any advice would be greatfully received!

My car had green stuff in it.... do I use green stuff again, or do I use the red stuff that Halfords sell??

Also... do I just chuck it in or do I need to do anything else? I\'ve rear about "burping" somewhere in the past?

How much does it take to fill the system??

Please... I need a "Jim is an idiot" guide to coolant... lol.

Is there anyway I can get away without flushing it?? I\'ve just read you need to flush it with EG?? Which can be expensive?

can you not flush it with boiled water?

RemarkLima · May 02, 2007, 09:59:38 PM

Do you really need to flush? Or just change the coolant regularly and use distilled water? After a couple of years it\'ll be nice an clean

Jim_rx7 · May 02, 2007, 10:09:28 PM

I don\'t know about the flushing thing. I just read you need to flush if you\'re not using the same coolant?? I had green stuff... but was gonna get stuff from halfords, which isn\'t green.

How do I fill, burp etc?

interloper393 · May 02, 2007, 10:10:52 PM

you flush it to get the right mix dont ya? plus to remove all the old crap if its been in there a while... just pop the hose onit and blow it all out lol

Jim_rx7 · May 02, 2007, 10:11:59 PM

A dunno... not got a hose... lol

Filling.. burping? ....

interloper393 · May 02, 2007, 10:15:47 PM

did you read the how to on that site lol? think you fill the ast first, them the middle tank..

Jim_rx7 · May 02, 2007, 10:22:16 PM

yeah mate... read it.

So you say...

fill the AST, then the middle, then the other one. Then run for 3 mins, burp.. and should be fine?

This is while watching for oil pishing out of the new oil cooler lines I fitted. lol

flushing mainly gets rid of scale from the system. do it every second coolant change

RemarkLima · May 02, 2007, 11:10:38 PM

OK, will flush next time

When I changed my coolant what really helped with me was to pull the coolant line off of the throttle body at the back and point it upwards, then slowly fill the system, I mean really slow!!! Then you\'ll hear most of the air escape from that hose. I had no problems with air locks so worked for me

Also I just emptied the rad (from the plastic screw in the bottom) and then the block from the small bolt under the spark plugs. Then just run some water through and refilled.

But my next one I\'ll do a full flush I guess.
