Radiator Reinstalled

I was hoping to get all of the heating and cooling components back into the engine bay this weekend, fill the system with coolant and start the engine up, but ran out of time and daylight. What did get reinstalled was the radiator, radiator fan shroud, coolant overflow bottle and mount, and the heater control valve - all with brand new mounting hardware and new hose clamps. At one point, while I was contorting my 6 foot frame under the dash to reinstall the heater control valve, I got my head stuck between the steering wheel and the shifter, and took the opportunity to remove the heater control unit and cables to have them cleaned since they were at "eye level" ... and I was waiting for the fire department to bring the "jaws of life" to dislodge me.

To my surprise, I found that there's a little 5W light bulb that goes into the heater control housing ... bonus! I know it doesn't seem like anything to get excited about, but the only lights that work in the interior of my car are those from the instrumentation panel on the dash, and the dome lights in the rear which were designed to work manually, or automatically when the doors are opened. Well ... mine don't work when the doors are open (another future project). Manual control works, but I can count that out as it's impractical to reach over to the back seats and flip them on. Anyways, when working, this little bulb is supposed to emit green light (via a green plastic filter in the heater control housing) down on the heater controls, presumably when the headlights are on so you can see where they are in the dark. The bulb looked intact, so I just cleaned the electrical housing and electrical contacts and plugged it back in. I'm not going to get my hopes up as it obviously wasn't working before, and the problem is most likely electrical, but hey - at least I found another non-working light source to add to the collection! FYI - map light aka tiny light bulb under passenger-side dash does not work, interior dome lights don't work when doors are ajar, left & right turn signal dash indicators only blink once when engaged (is this normal?), are there any other interior lights that I don't know about?

Engine Bay - Red & Chrome!

I took it easy this weekend. No major overhaul, just slowly reinstalling components that have been worked on the weeks before back into the engine bay. In order to get the heater back into the car, everything else that I removed has to be reinstalled in reverse order, starting with the repainted radiator fan and the chromed fan-belt pulley. The newly polished water outlet pipe was also reattached to the engine block.

Hood Support

Spent a week slowly chipping away at the hood support with the Dremel rotary tool, a half-hour each night grinding, deburring, and polishing until finally all the dirt and discoloration were gone. I've reattached it to the Volvo today, which means the hood can now stay open, thus paving the way for the rest of the stuff to be placed back into the engine bay.

Heater Rebuilt

At long last, the heater box has finally been pieced back together after being removed from the Volvo for almost 2 months! In summary, the entire unit has been sandblasted to remove old paint and rust, coated with POR-15 rust preventative paint, heater core flushed and checked for leaks, blower motor rebuilt, have all hardware replaced, and finished off with new seals and gaskets. Below are the before-and-after photos. Notice in this 1st series of 4 photos, the metal plate housing the defrost outlet has been repainted cast iron grey.

This next series of 4 photos show the rear of the heater box. All hardware have been replace with new ones (screws, washers, etc.)

The following photos show more detail work. The first shows the condition of the floor vent (before restoration) from the inside of the heater box. Here you'll notice the rust on the inside walls of the heater box as well as the corroded vent latch. The 2nd photo shows the defrost vent with new seal and restored vent latch. 3rd photo is the same floor vent in closed position. 4th photo shows the new drain tube which diverts any condensation from the heater out of the car via a drain hole in the floor panel.

In this final series of photos glorifying the heater box, the 1st shows the heater core being reinstalled. Later, the edges of the heater box was given an application of high temperature silicone gasket maker before the two halves were reattached. The 2nd is of the repainted plastic defrost outlet. The metal plate surrounding the defrost outlet has also been repainted cast iron grey. 3rd photo shows a vent spindle painted in POR-15 silver and reattached with new hardware. 4th photo - shows a new "D" style clamp washer securing the vent spindle on the opposite end.

New Colors

I've got lots of photos to share after spending the entire weekend with a facemask on and a couple of aerosol cans of paint. The first series of photos below are of the air duct which directs fresh air to the heater unit. The color scheme that I've picked for the engine compartment is black, cast iron grey, silver (or light gray), red, with some chrome highlights. The first photo below shows the air duct in its original black color. The second photo shows bare metal after sandblasting. The third is after 2 coats of POR-15 rust preventative paint followed by 3 coats of their tie-coat primer wet sanded down to a smooth finish. The fourth photo is of the finished air duct spray painted in cast iron grey.

The following series of photos are before-and-after shots of the radiator fan and the support arm for the battery. They've both been sandblasted to remove any rust and old paint, coated with POR-15 rust preventative paint, and coated with primer before the final application of red paint. I think the red accents against the black, silver, and cast iron grey of the other components in the engine compartment will add some dimension to the overall pallette. I call this the "Peacekeeper Color Scheme" from the farscape television series ... it's a sci-fi thing ... nevermind! I'm sure some P1800 purists will be screaming bloody murder because I changed the original color of some of the components - they can call me on this toll-free number to "express" themselves: 1-800-EAT-SHIT. Operators are standing by.

This final series of photos depict the process of getting one of these components from its initial banged-up condition to the final painted stage. Pictured below is the mount for the coolant overflow bottle. I meant for this to be painted in POR-15 silver initially and left as is without any top-coat because it won't be seen once the coolant overflow bottle is reattached, but as luck would have it, the silver POR-15 dried up in the can, so I had to work with black instead and top-coat with cast iron grey. After sandblasting to remove the rust, 2 coats of POR-15 were applied (2 hours between coats) followed by 2 coats of their tie-coat primer (which I would never buy again). The first coat of primer was applied 4 hours after the final coat of POR-15, when it was dry to the touch, but tacky with a slight finger drag. I found through experimentation that this is the only way to get that 1st coat of primer to adhere. The 2nd coat of primer was applied 12 hours later (after the 1st coat dried). After yet another 12 hours of curing, the primer was wet-sanded down to a smooth finish. All of this was done days or weeks prior to this weekend's paint job of course, as there is a lot of "down time" involved waiting for stuff to dry and only being able to do one side at the time for most components. The spray painting process is fairly simple. I like to start with 2 very light coats of paint with 10 minutes between each coat. 10 minutes after the 2nd light coat, I then blast it with a medium-wet coat of paint to get that smooth shiny finish.
