I'm reviving this thread as I'm over 6 months on both cars with 5w-30 full synthetic oil. Both cars have probably gone around 2,000 miles in this time. I don't think there are any engine issues, both seem to run fine, BUT both have developed very slow drips. Seems like both engines now have a...
I bought a couple of cheap float type testers. I tested them on a known 50/50 coolant/water mix and both seemed to read accurately. I then tested the fluid in the radiator after a couple of 10 minute trips, one seemed to indicate I was a little under 50/50 and the other seemed to indicate I was...
I did the flush this weekend. As usual it took longer than expected, and I'm second guessing myself on a couple of things, but that's typical for any job I do :)
In general it went fine. I drained the radiator and engine block, removed the thermostat, and pulled the heater core hoses to try to...
stower17, the pressurized cap is definitely on the radiator, the reservoir cap is non-pressurized. I also have a 2006 Yukon XL that has the pressurized cap on the expansion tank, confused the hell out of me the first time I saw it and couldn't find the radiator cap :)
incognito_2u, thanks for...
I wouldn't be surprised at all if it was never changed. I bought it used with 98,000 miles on it and first call for a change is at 150,000 (it's currently at 140,000 or so). When I take off the radiator cap it looks orange, like Dexcool would, although there's a bit of pink crust around the...
Ah, thank you for the clarification stower17, I wasn't picking up on the difference between overflow and expansion tanks. In this case the manual calls it a "reservoir" and says to fill it up to the "Full" mark, so pretty confident this would be considered an overflow and not expansion tank...
I appreciate the responses, but they're starting to get away from my original question. I'm really just trying to figure out whether the coolant capacity listed in the manual includes the overflow tank or not (and, I guess, would that mean the low mark, high mark, or something else?). When I...
Hi All,
I'm going to be doing a coolant flush on my 2008 Pontiac Vibe. My plan is to drain as much coolant as I can from the radiator, block, and heater core, then fill up with distilled water 2-3 times until it comes out clean, then refill with coolant. I plan to measure how much coolant I get...
Hi All,
I need to top off the power steering fluid in my 2008 Pontiac Vibe. The owners manual calls for Dexron VI. Currently in my garage I have Prestone Power Steering Fluid + Stop Leak ("Developed for use in GM, Ford, Chrysler, and most foreign cars and light trucks") and Valvoline MaxLife...
Hi All,
I've seen similar questions but not quite the same, and the answer is usually some variation on "it depends," so I figured I'd just ask.
I have two GM cars, a 2006 GMC Yukon XL and a 2008 Pontiac Vibe. I work from home so I don't drive all that much, I'd be surprised if either one went...
