Question: 48000 mile service

We were told recently after taking it in to a dealship that the collant was providing zero degree protection and may have a mix of red and green fluid? Coolant exchange recommended? Also told power steering is overfull and high side hose leaks. Recommends replacing pressure line. Also told that transfer case fluid is very dark, and they recommend servicing the transfer case and changing the trans filter. Further told us the "3rd" lamp was out and needed replacing.

Is it possible to have "red and green" fluid? If power steering fluid is overfull, can it be adjusted down and wouldn't that imply that perhaps that extra fluid has leaked onto the high side hose? Instead they recommend replacing the pressure line? Do we ned a transmission service at this point as well?

Thank you for your feedback.

You can see what is recommended by Jeep by clicking on the 'your service schedule' link.

Yes, it is possible to have a mix of different antifreezes, and they are considered chemically incompatible. Flushing the system out is the best way to deal with that problem.

If a power steering system is overfilled, it could raise the pump pressure up too high and damage something, causing a leak. Now that it's leaking, the hose needs to be replaced. It sounds like the coolant and the power steering fluid were improperly topped off--if you've been doing this yourself, educate yourself by reading the owner's manual. If you've been having it topped off at an oil and lube shop, go back there and have a chat with the manager and show them your repair bill because of their poor (but well-intentioned) service.

If the transfer case fluid is dark, it should be replaced.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
