When you flush your coolant, which is antifreeze, on your 2006, you are draining out all of the old dirty coolant and preventing costly radiator and cooling system repair down the road. Like the oil in your CR-V, coolant gets dirty over time and loses its ability to cool down your 2.4 liter engine. Turn off the engine and drain the water, fill up the radiator with antifreeze until you have a 50/50 coolant / distilled water mixture and burp the system. Fill up the radiator with distilled water and run the engine. This video shows where the radiator drain plug (petcock) is located on a 2006 Honda CR-V.

Start your coolant flush by draining the coolant / antifreeze that is in your reservoir, then drain the coolant that is in your radiator by opening the petcock or removing the lower radiator hose. In addition to preventing your car from overheating, coolant / antifreeze also helps lubricate the seals in the water pump and hoses. Coolant / antifreeze also passes through the heater core under your cowl to provide heat to the cabin of your CR-V. Coolant / antifreeze circulates through CR-V radiator and engine to maintain the proper temperature. Water is used to transfer heat while ethylene glycol is used to lower the bleak point of the. I suppose it's possible for a cracked head to be cracked in such a way that coolant is leaking into chambers but not oil but, in my experience, this is extremely rare.Learn how to flush the coolant (antifreeze) in your 2006 Honda CR-V.

Anyway, to sum up, head gasket failure is more common but intake gasket failure is the only other way exhaust could smell like coolant, especially if oil and coolant aren't mixing. My model had to remove battery tray & air. I know it was probably an accident, but they're not meant to mix as they are chemically different, resulting in reactions that can be problematic, like the sludge Paulster2 mentioned.

Coolant fluid exchange keeps cooling system running correctly In Vehicle Maintenanceby HomeTowne Auto Repair & TireFebruYour vehicle’s cooling system helps prevent the engine from overheating by ensuring that it’s running at a safe temperature. Paulster2 is correct here about the fact that it's just a matter of time before it gets worse, as well as testing for hydrocarbons in the coolant to confirm a gasket problem. It also sounds like the damage is small enough that the leak is slow, which could explain why you're not seeing a bunch of white smoke out of the exhaust just smelling it.

If your Honda is approaching its first 45,000 miles, it is an excellent decision to schedule routine maintenance including coolant fluid exchange. Sometimes, the damage is only between the coolant channel and combustion chamber. Honda generally includes coolant replacement at the 45,000, 75,000, and 105,000-mile intervals. The symptoms can vary by the location of the gasket damage, as well as the severity of the damage. All that means is that one of those gaskets are damaged or worn in a specific location. The only two possible ways that antifreeze will make its way into those chambers on its own is a 'blown' head gasket or intake manifold gasket. If you're absolutely sure that you smell coolant out of your exhaust pipe, then that means it's leaking into one or more combustion chambers, getting burned up and emitted out of the exhaust. ![]()
