What are the reasons for water ingress in the cabin of the old Santana?
2 Answers
The reasons for water ingress in the cabin of the old Santana are as follows: 1. Main driver's side leakage: Poor sealing of the hood cable and leakage caused by rust at the welding point of the drainage outlet. 2. Passenger side: Leakage caused by rust at the welding point of the drainage outlet. 3. Blower: Aging of the blower box sealing ring. Additional information: Impact and consequences of vehicle water accumulation: 1. Engine damage: Engine water ingress is a very serious issue. Water can enter through the air filter into the intake valve and then into the cylinder via the intake pipe. Do not attempt to start the engine in such cases, as it can cause deformation of critical components like the crankshaft and connecting rod, leading to engine vibration or even breakage of parts. 2. Brake failure: Water accumulation in the vehicle can lead to loss of braking, posing severe risks or accidents, especially for cars with drum brakes.
Back when I drove the old Santana, I also encountered water leaking into the cabin, most likely due to aged door seals. Over time, the rubber seals harden and crack, allowing rainwater to seep through the door gaps, leaving the passenger footwell constantly damp. Additionally, deteriorated windshield edge sealant can also cause leaks, especially noticeable during car washes when water drips down the A-pillar interior. Don’t underestimate damaged floor mats—if the chassis rusts through, driving in the rain feels like stepping in puddles. A clogged sunroof drain is even worse, as accumulated water can flow down the headliner into the driver’s seat. I once found the dashboard soaked and had to stuff towels underneath urgently. I’d recommend focusing inspections on these areas—older cars demand extra attention to such details.
