Blocked water flow in engine?
처리 내용
If this was in my bay I would proceed as follows: Repair fans: It will overheat at idle without the fans. The first test for this is to turn on the A/C, both, one or none will come on. Test and repair as needed. Test for system flow: Remove the inlet hose to the heater at the firewall. Test pressure and flow rate. A lot of water should be pushed out when the engine is revved. The pump should make at least 10 psi. This gives the relative heath of the water pump. The most common cause of poor flow in a Subaru is air trapped in the engine block. I would flow test the radiator and visually inspect the radiator interior. The flow tests is not very helpful. A radiator can flow great but not transfer heat if it is fouled with coolant scale deposits. From your description I would repair fans first, replace the radiator, put it all back together. Test after repairs by timing the fan run time. If the fans are off most to the time and the fans run only about 20% of the time and the fans blow warm

Hello! I have not driven my car for a month and now have this noise. It is a 2016 V Jetta and normally in great shape. The noise is in the background and sounds like something soft is rubbing against something. It picks up at 10 mi/hr or so and then stays on…Thank you! https://global.discourse-cdn.com/cartalk/original/3X/3/f/3f6ae6628ea80cf8d6b1899d0b2392d868545516.mp3

Power seat - Whenever vehicle is started or shut off and the seat slides forward of back, the power seat makes an annoying, obnoxious noise… I thought something was stuck in the track but now I think it’s the motor going out. Guy at the local dealership said it just needed grease. He appears to be incorrect. Any thoughts? Thoughts?

A buddy and I were trying to replace his right front wheel hub, on his 2008 Chevy Impala LTZ. He described the engine size as 3900, I would think that means 3.9 liter, although I didn’t know there is a 3.9, I only know of the 3.8 liter and 3,1 Liter. One of the mounting bolts is so tight that the socket would not keep a grip on the bolt head, no matter how hard we tried to force the socket onto the bolt head. We had tapped on it as best we could with a hammer and metal rod, we heated the area with a torch, no luck. Of course, very little access to this bolt head, so impossible to use an impact
