The correct way to bypass a heater core requires proper plumbing and is best done by a qualified mechanic. Improper bypassing can result in leaks and air in the cooling system. Simply disconnecting the heater hoses won't work effectively and can cause problems.
Here's why you shouldn't attempt this yourself without mechanical expertise:
* Overheating: The coolant needs to circulate properly. Bypassing the heater core alters the coolant flow, potentially causing the engine to overheat.
* Leaks: Improper connection of hoses can lead to leaks, spilling coolant which is toxic.
* Air in the system: Bypassing without proper bleeding will trap air in the cooling system, leading to poor heat transfer and potentially damage to the water pump.
* System pressure: The cooling system operates under pressure. Improper bypass could cause this pressure to be released in unsafe ways.
If your heater core is leaking or malfunctioning:
1. Find a qualified mechanic: This is the best and safest option. They have the tools and knowledge to properly diagnose and repair the issue.
2. Assess the situation: A small leak might be temporarily patched, but this is not a long-term solution.
3. Consider replacement: A new heater core is relatively inexpensive compared to the potential damage from a poorly executed bypass.
In short: While theoretically possible to bypass the heater core, the risks greatly outweigh the benefits for a non-mechanic. Focus on a proper repair or replacement instead. Driving with a compromised cooling system is extremely dangerous.
