Hi everybody,
Sorry if this is a dumb question I’m very inexperienced with auto repair.

Had to unplug this hose when I replaced my spark plugs due to a misfire. Plugged it back in and bolt snapped. Had to run the engine with friend holding hose in to make sure I cleared the misfire and some fluid leaked out.

Pretty sure it’s a heater hose but when I look the part up it doesn’t look similar. Fluid is yellow and I’m assuming antifreeze? When I fix it I should only need to refill the antifreeze correct?





Sorry again for the dumb question

 

Yea its the hoses for the heater core. Youll need to make sure theres not air in the system after you refill it. If its only the bolt that snapped, take the pieces to the hardware store and they can match it up for a few dollars.

 

Thanks for the reply! Do you know how I'd check if air entered? The tubes seemed like they had air in them already.

 

FYI, air in your coolant system is NOT a good thing. Look for these signs of trapped air. Below is a copy / paste about issues.

One of the most common symptoms of air in the coolant system is overheating. This occurs when air bubbles prevent proper coolant circulation around the engine. Other symptoms include a gushing sound inside the dashboard, a lack of hot air from the heater, and a leaking head gasket. It’s important to address these symptoms as soon as possible to prevent further damage to your vehicle.

Now that you have read that, it's pretty simple to purge the trapped air, do a You Tube search on bleeding the air out on the Monte Carlo thermostat housing.

Or pull the passenger tire up on a curb, so car is angled with passenger front side higher than rest of car etc. You want it so the radiator cap is elevated higher than the rest of the radiator. Remove the cap, let the engine run for 20 min or so and you will have burped out the air. Insure you run your heater at the same time. Put the cap back on and go enjoy your Monte...

 

Thanks for the info! Will make sure to purge everything.
