There are two tanks: the coolant expansion tank and the windshield washer fluid tank. If it's the coolant expansion tank: If it's the coolant expansion tank: The most common scenarios: The water temperature is too high, leading to excessive pressure that causes the tank to burst; collision; the expansion tank is overfilled with fluid; using tap water instead of coolant. If it's the windshield washer fluid tank: If it's the windshield washer fluid tank, it might be due to a collision or inherent quality issues. This tank is not pressurized and won't burst without reason. Overall aging of the tank can lead to cracking under certain conditions, similar to how glass can shatter on its own in daily life.

How to Remove the Door Panel of a Buick Excelle?

Method for removing the door panel of a Buick Excelle: 1. First, remove the window regulator panel, which is usually secured with clips—carefully pry it off; 2. Disconnect the control wires, taking care not to damage the wiring, then remove the adjacent fixing screws and detach the door handle; 3. Pry off the fixed panel of the door switch, applying gentle force to avoid damaging the interior trim. Once these steps are completed, you can begin removing the door. The door panel is secured with clips, so there are clips along the edges that need to be carefully pried open. After prying off the door panel, store the fixing clips properly to prevent loss, then disconnect the wiring harness connectors on the interior panel. The removal of the Excelle's door is now complete. The Buick Excelle measures 4609mm in length, 1798mm in width, and 1464mm in height, with a wheelbase of 2640mm.

What Causes Unstable Engine Idle Speed with Fluctuating RPM?

Engine idle speed instability with fluctuating RPM is caused by: oil accumulation and carbon buildup in the throttle body, excessively dirty intake passages, fuel system blockages (particularly in fuel injectors), and intake manifold malfunctions. Unstable idle speed is one of the most common engine faults, ranging from minor to severe issues. Normally, engine idle speed should remain constant. Generally, higher idle speeds lead to increased fuel consumption, while excessively low idle speeds may cause engine vibration or even stalling. Oil accumulation and carbon deposits in the throttle body, along with dirty intake passages: Blocked intake passages can cause idle speed fluctuations. Carbon buildup or oil presence in the throttle body is a frequent cause of idle instability. Throttle body carbon deposits affect its opening angle, disrupting air intake volume. This results in erratic RPM fluctuations during cold starts, accompanied by noticeable vibration.
