Ok so far this site has been so helpful! just did my custom intake yesterday!
Ok so i went to check my coolant today and noticed it was low and it was dirty and clumpy . so i was wondering could i flush it myself? went to a side mechanic (i know bad idea) and he said something about a back flush? and that he would charge me 75. i wouldn't let him do the job anyway.
So is it DIY friendly? also should i trust the screen that says how much oil percent i have left? i checked my oil and its seems a bit low, so should i add some more? what kind should i add? the guy who i purchased it from said he only uses royal purple. so should i just add some more i that?
Also what kind of coolant should i use? is it Dexcool? im kinda new to this whole car maintenance and want to keep my GTP in excellent condition. Thanks you guys
