How do you flush DexCool sludge?
I’ve had good luck flushing dex sludge from heater cores using vinegar. I generally flush most of the crap out and then soak the core with 100% vinegar for a few hours/over night and then flush with water some more. I repeat until it runs fairly clean.
Why is DexCool bad?
Cooling systems that use Dexcool exhibit more acid buildup and rust in the system when the coolant level gets low and oxygen is allowed to enter the system. The acid eats away at head gaskets and intake gaskets. Rust builds up in the system, inhibiting coolant flow, which causes overheating.
Is DexCool still a problem?
GM still uses Dex-Cool coolant and there is no longer a problem with gasket coolant interaction. So contrary to the ranting, DexCool IS the recommended coolant for GM engine.
Does Dexcool damage your engine?
Ten years after General Motors began using Dex-Cool as an antifreeze in most of its cars and light trucks, GM car and truck owners continue to complain that the coolant corrodes and clogs radiators and radiator caps, erodes water pumps, rots radiator hoses, causes chronic overheating and engine damage while leading to ……
Can Prestone Dexcool be used in Fords?

Does Ford use DexCool?
The new Ford coolant is OAT and is not compatible with DEXCOOL. You cannot go by the color of coolant anymore an have to use only the one that meets the specifications of your vehicle. Using the incorrect coolant can damage cooling system components and cause engine components damage or overheating….
Can DexCool be mixed with regular antifreeze?
Do not mix Dex-Cool with regular anti-freeze! Dex-Cool is a specially formulated GM coolant which will not mix with traditional coolants, and was used in various GM applications up through the 2004 model year.
What happens if you use the wrong color antifreeze?
If you do mix different-coloured coolants they generally do not mix well and some can form a gel-like substance. This will halt coolant flow, causing blockages that can lead the engine to overheat, as well as damage to the radiator, water jackets and heater core. Also, the water pump can overheat and fail….

CostHelper.com estimates the cost between $54 and $144 for a radiator flush at a standard shop, with an average price of $99….
What happens if you mix 2 different antifreeze?
The two coolants should never be mixed together as they do not react well. When mixed together they can form a thick, jelly-like substance that can completely stop all coolant flow which can lead to overheating….
What happens if you don’t dilute antifreeze?
Your car can or will potentially overheat. The Non dilute coolant has properties to go so far, but it needs water to be mixed so it can be the best it can be. Concentrated engine coolant (ethylene glycol) has poor heat transfer abilities. After it gets hot, it will not effectively transfer heat from the engine block.
Is it okay to mix coolant brands?
Can the wrong coolant cause overheating?
The wrong coolant or the wrong mixture of coolant and distilled water can cause your vehicle to overheat. Coolant actually becomes corrosive over time, accelerating the wear on the cooling system!…

Why does my car overheat but not idle?
In some cases there may be air pockets in the heater core which can cause the heating of the inside of the vehicle to fluctuate between warm and cool air erratically. Engine overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, or a failing coolant fan switch….
