Yes it is the cap on the plastic radiator fill tank
There is not a radiator cap, there is a coolant reservoir and it has a plastic cap that controls the pressure in the coolant circuit.
how to change radiator 1995 jeep grand Cherokee Laredo
it's right behind the front bumper. in front of the engine. there is no radiator cap on it. only the heater core is on the radiator.
It's just behind the radiator down low, in the center. It has a blue cap on it, you can't see it from above, best thing is to crawl under the nose and look just behind the radiator. Once you know where it is, you can reach for it from the top but it's almost completely hidden from view from above.
It is under the housing that the upper radiator hose hooks to on the engine.
For a 1995 Pontiac Grand Prix, you should fill the radiator coolant to the full mark indicated on the coolant reservoir, typically around the "Full" line. Ensure that the engine is cool before opening the radiator cap, and add the coolant mixture of antifreeze and water in a 50/50 ratio. It's important not to overfill, as the coolant expands when heated. Always check the owner's manual for specific recommendations.
The assumption is, the engine is hot and if you open the radiator cap you will be sprayed with hot radiator coolant. If I'm not mistaken, didn't the 95 Buick use the "permanent" radiator coolant? If so, don't change it until the specified time. Just don't open it while it's hot. Do it when the car is cool.
I assume you meant 95 Ford Contour. There is no bleeding when replacing antifreese. Just fill the radiator recovery tank as there is no radiator cap on these vehicles.
Low coolant? Bad thermostat? Water pump not circulating coolant? Defective radiator cap not building proper pressure?
You might need to either replace your thermostat or the radiator itself. I can't tell what "tube" you're talking about, but it COULD just be the radiator cap that's bad and you're venting into the tube that goes to the coolant recovery reservoir. If that's the case, just get a new radiator cap. If the radiator hose is leaking, replace it. Unfortunately, I can't tell what's wrong from your description.
All I do is remove the radiator cap (wait until car is cold and open cap slowly) and start the car. let it warm up. the thermostat will open and begin fully circulting the coolant. if there is any air bubbles in the system they should work theirselves out. another thing to do after the thermostat opens is slowly squeeze on the lower radiator hose, careful not to spew coolant out of the radiator.
