New Blower Motor

My blower motor was horrendously loud and didn’t always work on the low speed. I bought a replacement, and finally found time to install it. The has lots of corrosion in it.

I’m happy to report the new motor is quieter and works on all speeds.

Tools used:

  • Short ratcheting driver
  • 9/32 bit

New Brake Hoses

Two years ago, a fellow Delorean owner had one of the original brake hoses fail. The hose was acting as a check valve, so when the brakes were applied, the caliper would not retract. I helped the owner replace his front hoses to fix this issue. I had also read about other problems with the original brake hoses. Looking to avoid any problems, and desiring the firmest brake pedal possible, I decided to replace my original brake hoses.

My car club’s spring tech session was hosted at a local repair shop, where we had a car lift available. This was my best opportunity to get all four of hoses replaced.

Disconnecting and re-connecting the hoses on an automatic transmission car for the back wheels is a major PITA. The transmission being in the way makes access very difficult. Being at a repair shop, I could borrow the metric crowfoot flare nut wrenches and extensions needed.

I didn’t get many pictures because I was focused finishing before we had to leave the shop.

New Hoses:

Old hoses:

After getting everything installed, and bleeding the brakes, I found brake pedal was still soft. At home, I made sure all the connections were tight, bought some more brake fluid, and bled them again. This time the brake pedal is the firmest it’s ever been!

New Transmission Filter, New Pan Gasket, Coolant Flush

Automatic Transmission filters have not been available for many years. The only options were:

  • Find an NOS filter
  • Cut apart a used filter, replace the filter material, and weld or use aluminum tape to seal it back up
  • Don’t use a filter

…until now! One brave individual took up the cause, and found a company to reproduce them! After buying one, two years ago, I finally got around to replacing it. Draining the ATF:

I tried getting the pan off without disturbing the coolant system, but there was no wiggle room. Oh well, the car could use a coolant flush anyway.

Looks like someone used the cut, replace, and weld method on my existing filter:

There was a decent amount of material on the magnet:

Cleaning the pan:

I liked the quality of the new filters so much, I bought two extra:

New filter installed:

I’m interested in getting rid of any ATF leaks, so I bought the silicone transmission pan gasket offered at DPI:

The bolts I had for the transmission pan started to spin while torqueing them. The new gasket is thicker than the previous one. After some panic, purchasing and installing longer bolts solved the problem.

Time to refill the trans:

Bleeding the coolant, and looking for leaks! Ready to be back on the road after 5 months of winter!

It still leaks ATF. It will always leak ATF:

Roadkill.com Article!!!

While showing my car at a local car show, someone stopped to talk about the car, and was asking a lot of detailed questions. Sure enough, he’s a writer for RoadKill.com! The writer, Eric, asked about writing an article on the car. In September, we got together after several emails. We did a photoshoot, and an interview. In November 2016, it was published!

Check it out: http://www.roadkill.com/great-scott-hung-delorean-national-laboratory/

Roadkill has become one of my favorite shows. It is a big honor that there’s an article about my car, and me, on Roadkill.com!
Thank you, Eric!

One Piece Clear Evaporator Drain

The stock evaporator drain is very prone to clogging with debris. The location makes it also very difficult to clear the clog. It starts in the passenger side of the car, between the evaporator box, and the underbody. It’s a small gap, around 1 inch:
Drain 30 Drain 20

There’s a reducing 90 degree elbow, connected to a short hose that drains into the passenger side front wheel well, right onto the frame:

I previously vacuumed out my cabin air intake, and put a screen over it to keep debris out: http://www.16908.info/?p=1562

However, my AC drain clogged. I didn’t find this out until a good amount of water built up in my passenger side carpet.

The recommended way to clear the clog is to run some weed-wacker cutting line into the hose, and poke around to free the obstruction. Some people have had luck using a vacuum connected to the drain hose.

I found the hose was loose, and easily pulled off. I’m not sure it was even connected, and getting it reconnected was going to be very difficult with the AC dryer in the way:
Drain 10

The stock elbow can be cut with a thin saw blade, or gently heated and pried off. The saw method could possibly damage the box or nearby wiring. I opted to use the heat gun, and screwdriver to pry it off. Once I got it off, more water drained onto the cabin floor, and some out onto the ground:
Drain 45

Here’s the reducing elbow, all clogged up:
Drain 35Drain 40

I’ve seen mods where spark plug boots, or coil cover boots are used to make an easily detachable piece to drain water. I decided against any kind elbow, or connection in favor of one single piece of tubing.

I had a length of Chemical-Resistant Clear Tygon tubing left over from building a brake fluid pressure bleeder:
Drain 50

I then boiled some water with a kettle, and held it over the steam for a few seconds. Then I shoved a scissors into the tubing, and opened the scissors to stretch the tubing. After a few tries, I was able to finally get the tubing around a 13mm socket:
Drain 55

I also used the steam to work the tubing into curve. The stock elbow is a hard 90 degrees, so this gentle curve should reduce clogging. Here’s the old drain, and the new one:
Drain 60

The tubing has a 1/16″ wall thickness, and is very rigid. The inner diameter is 5/16″ and appears larger than the stock elbow:
Drain 90

Now I worked the tubing into the hole in the underbody, and got it out into the wheel well:
Drain 65

After some twisting, I got it into position, and onto the evaporator drain:
Drain 61

Blowing air through the tube was easy, which confirmed there were no kinks. Now I angled it down, below, and away from the frame. A zip tie secured it:
Drain 70

Whenever I vacuum my interior, I’ll also attach it to the drain hose to suck out any debris which may have found its way into the hose. Hopefully this will keep the drain clog free, and my carpet dry.

To summarize, here’s the benefits of this mod:

  • Clear tubing allows a clog to be seen
  • longer tubing allows water to drain away from the frame, reducing frame rust
  • Eliminates 90 degree elbow, reducing clogs
  • Larger internal diameter tubing reduces possibility of clogs
  • One piece can’t become disconnected in the wheel well
  • Easier to vacuum or snake out debris
  • No need to cut or modify the underbody

Tools:

  • Heat Gun
  • Long flat blade screw driver
  • Scissors
  • 13mm socket
  • Tea Kettle

DCS 2016

I attended the 2016 Delorean Convention and Show. The location was around 175 miles away in Springfield, IL, which made driving very manageable. I also did some volunteer work for the convention.

Driving to and from Springfield, I discovered a few problems with my car:

  • I definitely have a “hot-start” problem with the K-Jet. Restarting the car after driving over two hours in the heat was very difficult. I plan to replace the accumulator since it’s original to the car.
  • My evaporator box drain is clogged, and soaked my passenger side carpet. More on that later.
  • The fuel pump boot cover popped off, and was letting fumes into the cabin.
  • The fuel pump still hums loudly after a long drive, with hot gas in the tank. Someone measured an increase in gas temperature from the gas return line. The hot air dam probably helps keep hot air away from the fuel tank, but doesn’t keep the gas tank cooler when returning gas is hotter than when it left.

Anyway, my car still made the trip safely. Here’s some pictures:
