I am going to flush my radiator in my 1999 cobra is there any brand or type of coolant i should use or any additives? Also im going to flush my trans and my rear end any suggestions on that what to use and how much?
Coolant...I use the stock replacement. Usually it will be the green stuff.
Trans fluid....ATF...the brand...thats up to you. Just fill it through the shifter opening, with the top (fill) plug out. Make sure it is on level ground. When it comes out the top fill hole stop. Put the plug back in...your done. T45's and TR3650's should be 3.5-3.7 quarts.
Diff fluid...if you asked...can't remember....just over 2 quarts of fluid and one bottle on friction modifier. Some use 80W90, some go with 75W140. DO NOT OVERFILL...you will burn out your clutches. I put 3 quarts in while the rear end was out...installed it....put it on level ground...then pulled the fill plug......a lot leaked out. I put the plugs back in and drove home.
The only cooling system additive that I've used consistently is Red Line Water Wetter. Folks that have real working guages indicate that it does help keep temps in line.
I'm using Red Line fluids all the way back. So far so good.

+1. i had issues with my 97 GST wth a front mount intercooler cutting off alot of airflow to the radiator. with DSMlink i could record my temps in realtime, sitting at a stop in 110* cali heat my temps were around 215*, and during cruise 200-205*. added redline ww and i saw 195* at a stop and 185-190* during cruise. it ****ing works.
as for other fluids, i use Royal Purple. some say its just gimmicks / snake oil, oh well, i feel it works (made a nice difference in my 02 GT going from standard to full synthetic RP), my cars are worth it.
just making sure here for the Trans on a cobra you only need 4 quarts of fluid and thats all. for rear end you need 2 quarts of fluid and one bottle of friction modifier. just want to make sure i get everything the first time. and should i go with 75W140 or something else
