at 50k i did a coolant flush at jiffylube now i 100k and wanna do it again but i hear that i should use only nissan coolant or equivalent. so is jiffylube ok or not?

 

Coolant is coolant, it's fine to take it to them.

 

I think Iffy Lube is using a run of the mill coolant with silicates and phosphorus that your Max is better off without.

Do the flush yourself with distilled water(it's easy just time consuming) and use Japanese coolant.

 

Get like 7 or 8 gallons of distilled water from Walmart (88 cents) and a gallon of Honda, Toyota or Nissan coolant. Follow the how-to sticky.

 

You should be doing the radiator flush every 30K, not every 50K.

 

i thought it's 60k..oh well

i might be doing it at Midas. they are the only ones that can do my 5-speed tranny refill. the rest of the shops were like WHY CHANGE IT? IT THERE FOR LIFE.

 

Nissan coolant "or equivalent" the prestone "all makes and models" should be good right?

 

probably should have gone to dealer or done it myself. Midas HAS NO FACKING idea on how to do it right. all they can do is hook up machines that do the flushes. took them about 40 minutes to drain and fill tranny with AMSOIL (btw. don't feel any difference in shifting vs OEM fluid). The coolant they only drained from radiator (had no idea about other drain plugs and opening heater core). oh well i guess most coolant got replaced anyway with Nissan one. just hope they mixed it 50/50

 

Do'h! Now you know...
You should check the tranny fluid level to make sure is ok. To check the mix in the cooling system, you can get one of those cheap coolant testers (http://www.prestone.com/products/accessories.php).

 

i'll buy that

tranny fluid is ok. motor oil is ok. alighment is ok. wheel balancing (2 wheels) NOT (will go to sullivan tire for road force). coolant they said they mixed 50/50 and flushed radiator. plus they fixed my flat tire. with out the fluids costed $180
not that expensive. if i went to dealer it whould have been about $260 or more

 

u either do it yourself or take it to dealer and pay premium price. any shop can fukc up easy. NTB tire is pretty well known and they put 6 qt of oil in my car at the oil change.

 

Oh yeah, no question about that. That's why some many members are DIY'ers. It pisses me off to find an overfilled engine or tranny.

 

don't know about autos but 5-speed u can't overfill. thats why i don't worry about tranny fluid

 

don't know how accurate this thing is, but it's showing my car and my dads car that its much more coolant then water. i need to get 100% coolant and mix it with water in a can and test it.

 

found a post dated 2001 (not here) talking about inaccurate that tester is. also recommended this:
