okay, we just switched the radatior because the old one had a leak, filled it back up with 100% antifreeze, not the 50/50 mix honda suggests...was that a mistake? For some odd reason the car idles strange now...it shakes when idling in drive/reverse(auto), not like its dying but its not as smooth as it was.

Any input would be appreciated.

 

Fully bleed the system? And why do you put help please in the topic, do you think we ignore the topics that say please.

 

You need 50/50 mix, do not use straight coolant.

also you need to burp and bleed the whole coolant system.

 

I bleed the system, and I'll go ahead and do the 50/50 tomorrow.

Thanks for the reply.
