Philips X-treme Vision Headlight Bulbs

Since I was on car repair mode, I decided to replace the Sentra’s headlight bulbs. They, actually just the low-beams, went bust over the last few weeks and I have been running around on fog lights. Or on high-beam where possible.

I was pretty impressed with the busted lights, Philips X-treme Power Headlight Bulbs, which had lasted almost four years so I decided to get them again. But the only one available at the shop were DiamondVisions. I pressed them and they offered to get X-treme Visions, apparently the replacement for X-treme Powers, from another branch. It took a long time in coming so I had to leave without new bulbs.

I was finally able to get them tonight after groceries. I tried to install them before leaving the mall but I wasn’t making any headway. I gave up and headed home where I gave it another go. This time, with the aid of an LED keychain light, I finally met success. Now I have not just 50%, not just 80% but 100% more light than stock bulbs! Night driving’s gonna be so much more fun!

 

 

Busted Evaporator

Brought the Sentra to Frigid Zone today. The aircon wasn’t running and I figured there’s a leak somewhere. The diagnosis: there’s indeed a leak and it’s in the evaporator. That’s the bad thing. The worse thing is that I had that same evaporator installed brand new from the same shop just over a year ago. I was naturally rather unhappy but it is past the warranty period (6 months). At least I was able to get a small discount, a longer warranty (1 year), and an assurance, unverifiable until next year, that the new evaporator is of a better make.

Engine and Air Cooling Systems Fixes

Just before Holy Week, the car overheated because the radiator fan wasn’t automatically activating. The aircon also died. My theory was that the overheat resulted in the refrigerant to go hot, over pressured, and got vented out by some pressure relief valve. I direct-connected the radiator fan so that it’s always on. Not a long-term solution as this will shorten the life of the fans. I also made do without air conditioning. Or rather Michelle did.

Today, I visited Fusion R and they confirmed that the radiator fan wasn’t working properly because the radiator fan temperature switch connector was loose due to a broken clip. They tried looking for a replacement but couldn’t find any. So what they did was remove the old temperature sensor and connector and replaced them with ones from a Subaru. Total cost P3000 for the Subaru stuff and labor. Ouch! At least the car has a little bit of Subaru genes now :P

But it wasn’t over yet. Next, I went to the aircon shop. They said everything seems okay, there are no visible signs of a leak.  So they’ll just recharge the refrigerant and observe if there’s a leak. Bad decision. In just a few minutes the refrigerant was gone again. There was definitely a leak.

They pulled down the evaporator and the pipings to look for it and sure enough there was a huge one in the piping near the radiator. The radiator had somehow sawed a hole on it. They brazed the leak shut, reinstalled everything, and recharged again. Total cost P950 for the initial recharge and P2650 for the pulldown and repair. Ouch again!

It became clear what happened: The radiator abraded the aircon piping until it finally blew venting out refrigerant. The aircon system detected the low level of refrigerant and shut down as a failsafe. This means the radiator fan and auxiliary fan didn’t spin as they usually do when the aircon switch is on. Since the radiator temp switch wasn’t working properly, the radiator fan didn’t turn on and the engine overheated.

Ignition Coil Problem and Others

Michelle asked me to get the car checked as the vibrations were getting worse. I’ve previously ruled out the engine as the source of the vibration. I know that it’s because of the rubber hood stoppers (or the lack of) and the radiator fan. But I also needed to have the engine oil pan resealed due to a leak. Plus it’s due time for an engine oil change.

Deciding to do everything one time, I headed to my favorite Shell quick lube shop.  Unfortunately, when I got there, I learned that they don’t do oil pan resealing. Since resealing requires the removal of the engine oil, it makes sense to do the resealing and the oil change together. So I headed out, this time towards Fusion R, my favorite car repair shop.

On the way, I kept watch for an auto supply shop where I can by rubber hood stoppers. I found one that had an available parking. I turned in, parked, and bought two stoppers for P75 each. The staff was helpful and they even installed them. No more hood vibrations!

I got back in the car and started the engine. Engine won’t crank. Thinking it’s the upward inclination of the parking, I neutraled down and tried starting again. Still won’t. I asked for the help of the staff and they pushed the car up the incline and back to where I was just a minute before.

The shop owner came out, later followed by the mechanic, and they diagnosed the problem to be the ignition coil. They replaced it. They also noticed the radiator fan problem and diagnosed it to be the motor. Since I knew that it has a problem already, I agreed and they replaced it too. Since I was there, I also had my oil change. My bill quickly ran up to P5,270. Ouch! But there certainly was a huge improvement in the noise and vibration levels.

Forgot about the oil pan resealing.

Frigid Zone

Less than a month after I had its refrigerant replenished, the Sentra’s aircon is not cooling again. So this morning, I went to Frigid Zone, my favorite car aircon shop. They used to be near, they’re not of the small side-of-the-road variety, they have an air-conditioned waiting area, and they accept credit cards.

After a taking down the components and inspecting them, they confirmed that there’s a leak and it’s in the evaporator. So that had to be replaced. And because of the leak the system was contaminated with air and moisture as there was no positive pressure to keep them out. This means the dryer (it’s really a disposable filter) and the expansion valve (not sure about this having to be replaced) also had to be replaced and the system flushed (i.e. vacuumed out to remove any air and moisture). I ended with the following bill:

  1. Cleaning, flushing, and refrigerant recharge P1300
  2. New evaporator P5000
  3. New expansion valve P1500
  4. New dryer P1200
  5. New fittings P600
  6. New o-rings and valve cap FREE

More expensive than smaller shops. But the parts were new and in good condition and the technicians did their work quickly and neatly. It took around 2 hours but I sure hope the fix lasts more than 2 years. So far it feels good and cold.
