If your jeep is running hot, you got problems elsewhere. Nothing wrong with the green coolant imo. My jeep has a new rad, t stat, and water pump, and green coolant. Runs cool even on the hottest days

Many people have had issues. And they are not isolated events. GM lost a class action lawsuit because of Dex.

Too bad they focused on the Six cylinders because my 5.7 had the same issue and ended up costing me $1800 to have the issues fixed.
On my truck the Dex ate away at my intake manifold causing coolant to leak onto the intake valve. Valve then gummed up and stuck open. Valve was bent and the fuel injector was melted. Bad thing about the Vortec 5700 you can't just change one injector you have to change the entire central point injection (spider).
Run it if you want but I wouldn't. It doesn't perform any better then other coolants. Only benifit is longer life. But is the gamble worth it?

WASHINGTON -- General Motors Corp. has agreed to pay as much as $800 each to millions of customers to settle lawsuits that it sold about 35 million vehicles with faulty coolant and engine parts.
The move announced by lawyers Wednesday would close one of the largest product-liability lawsuits faced by a U.S. automaker. GM declined to say how much it expected the settlement to cost, but the agreement gives payments to customers even if they bought the vehicles used.
The suits stem from GM's use of Dex-Cool, a coolant it first introduced in its vehicles in 1995 and sold in more than 35 million cars and trucks between 1995 and 2004. About 14 federal and state lawsuits seeking class-action status have been filed against GM over a variety of problems in V6 engines linked to Dex-Cool.
Thousands of customers have complained of problems ranging from small coolant leaks to complete radiator and engine failure. Court documents show that GM has received tens of thousands of repair requests linked to Dex-Cool and engine gaskets in the affected engines, and considered recalls for some models.
Under the settlement approved by a California judge last week, people who paid for Dex-Cool-related repairs on 3.1-, 3.4-, 3.8- or 4.3-liter V6 engines within seven years or 150,000 miles are eligible for some payment from GM. Repairs made within the first five years are eligible for up to $400, while sixth-year repairs could receive $100 and seventh-year repairs $50.
