I currently have this problem with my Grand Am. I was told that it was the intake manifold gasket a kind of costly repair if you can't do it yourself. A lot of GM vehicles have this problem because they use the coolant DEX-COOL which wear away at the manifold over time. Doing my own research I found out that most manifolds on cars who use this type ofcoolant should get their manifold changed at about 60,000 miles. Some wear down before then. I believe that GM has made a better manifold to which it wouldn't wear as fast but I know many repair shops I have spoken with recommend that I get my coolant system flushed to have it use another type of antifreeze.
Having to add collant & coolant leaking from the hose.
You have a leak in the cooling system. If you don't see evidence of coolant leaking on the ground, you probably have a head gasket problem. Have the system pressure tested soon before more serious damage is done.
Coolant reservoir, or directly in the radiator. If you are having to add much coolant, you need to find out why. Serious engine damage can occur if it is leaking inside the engine.
You do not recharge coolant, you replace it. If you are referring to refrigerant in the A/C unit, then first you need to have the leak repaired. It would not need recharging unless it is leaking. It is illegal to add refrigerant to a system that is leaking without repairing the leak. This is a job for a professional with the proper tools and knowledge. This is not a DIY repair. The cost depends on where the leak is.
There are marks on the side of the coolant reservoir that indicates the proper level. Keep it filled at all times if you are losing coolant you may have a leaking hose or may be your Lower intake gasket. you should not ever have to add coolant to your system.
The brake fluid must be flushed out as soon as possible If you have to add water keep going its OK Drain and change the coolant as soon as possible.
I would doubt you would pour engine block sealer into coolant. More likely it would just need to be put in with the oil. Like lucas. I dont know your particular product. Depends also, are you leaking coolant, or burning it?
the hole it is leaking from is their as a warning your water pump is going out . if you don't change it soon it will be a big leak
how to add coolant to 1991 lumina?
There is coolant on the ground occasionally. How will I know when the intake manifold gasket is leaking
The overflow resavour is where you add coolant
You add coolant to a C240 at the radiator overflow tank. This allows the radiator to suck in coolant as needed when hot.
