Hello,

I will be changing the coolant in my car perhaps this weekend and looked at the instructions in the FSM. Steps 6 and 7 say the following in the FSM:

6. Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000 rpm.
* Make sure thermostat opening condition by touching radiator hose (lower) to see flow of warm water. Caution: Watch water temperature gauge so as not to overheat engine.
7. Stop engine and cool down to less than approximately 50 C (122F).

So in regards to step 6, would I rev the engine at 3000 rpm for 10 minutes or do I drive the car for 10 min around that rpm level? As for step 7; how would I know the temp has reached 50 C since the gauge inside the car doesn't actually tell anything? Also, is the "water temperature gauge" that the FSM is referring to the one on the dash board?

Sorry for the noob questions but any help/explanation would be greatly appreciated. I did look at some old threads for coolant change but they still didn't answer the questions I have.

Thank you,
Alex

 

go to infinitihelp.com there is a DIY there explaining everything you need and need to do. very detailed

 

you can let it idle, rev it up, drive it around it doesnt matter just get it warm. at when you let it cool just let it cool enough so that its not boiling and water will no spray up at you when you open the radiator. let it sit for about 10 minutes. when you turn the cap let the pressure out if any before opening it up all the way.

 

Thank you for the info!

 

follow fsm instructions; they don't say anything about opening up the pressure cap - just my $0.02
