Repair Mistakes & Blunders
Repair Mistakes & Blunders

Back in the 1970's, my partner and I ran a two bay gas station. A customer came in with a VW Beetle, with gas tank under the front hood, complaining of intermittent engine stalling. With a full tank, the car ran fine, but when the fuel level was below ¼ tank (he had to guess as those cars had no fuel gauge), the engine would stall. He would wait a couple minutes, the motor would start and run fine for a while, then stall again. We replaced all the normal items like points, plugs, condenser; checked and tested the distributor, timing, fuel pump, carburetor, hose, etc. The problem persisted. Finally we drained and removed the gas tank, turned it upside down, and out fell a fibrous seal from the cap of a bottle of fuel additive the owner had recently added!

Apparently, the seal would float until the gas was low enough that the suction from the fuel pump would suck the seal over the port, shut off the fuel flow and stall the motor. When the suction was relieved, the cap would float back up top until it was sucked back down again. At full tank, it was too far away to be affected by the suction. Once removed the motor ran fine again!

Automotive Trivia
Automotive Trivia

What was a common heating system used on cars built 100 years ago?

A. A valve (typically under the hood) was opened to route hot engine oil through a finned oil cooler located under the dash. Most oil coolers used very thin tubing, but some engines required extra oil to be added to the crankcase.

B. A steel "heater box" containing burning charcoal or a preheated brick was placed on the vehicle's floor.

C. Electrical current was routed through a large heating element (resistor) located under the dash. Some generators could not generate enough current to power both the headlights and electric heater at the same time.

D. All the above

Your Cooling System & Electrolysis
Tom's Story

I have caught myself thinking, "Why did that heater core fail again so soon?" and then discover the heater core was actually last replaced 10+ years ago. (I avoid losing track of time by using my RockAuto account to see when parts were last ordered/replaced. To create an account, go to upper right corner of the RockAuto home page or look under "Menu" on a phone.)

Electrolysis is the likely culprit when "fail again so soon" is for real, and new heater cores/radiators quickly start leaking. Electrolysis eats away metal in the cooling system and the relatively thin walls of heater cores and radiators are the first to fail. There are two primary causes for electrolysis; acidic coolant and bad grounds. An inexpensive multimeter can be used to diagnose both.

Below are some general diagnosis tips/techniques. Visible dark spots on the exterior surface or the heater core/radiator can be another sign of electrolysis. Consult your vehicle's repair manual (found under "Literature" in the RockAuto.com catalog) and/or seek the advice of your spouse, mechanic, attorney, etc. for more specific instructions.

Typical Multimeter, Radiator & Heater Core
Typical Multimeter, Radiator & Heater Core

Acidic Coolant:
Old coolant can become so acidic that it begins conducting electricity and moving metal like the acid in a car battery. Take the radiator cap off the cold radiator (so no pressure builds). Start the engine and allow it to warm up enough for the thermostat to open and coolant to begin circulating through the cooling system.

Switch the multimeter to one of its lowest DC voltage settings. Stick one electrical probe in the coolant and put the other probe on the negative battery terminal. A reading of 0.4 volts or above indicates electrolysis is likely happening.

Loose, Missing or Corroded Electrical Grounds:
Now with the engine off and the battery disconnected, again stick one electrical probe in the coolant and put the other probe on a metal engine part (ground). If the voltage is still 0.4 volts or higher with the battery disconnected then old acidic coolant is indeed the culprit and should be flushed and replaced.

However, if the voltage reading is 0.00 with the battery disconnected, then there is a bad ground somewhere in the electrical system. Corrosive electrical current is being misdirected through the cooling system.

Solutions:
Acidic coolant should be flushed out of the cooling system and replaced with the correct new coolant (find Coolant/Antifreeze under "Cooling System" at RockAuto.com). It is often good to flush the system more than once to thoroughly remove as much old coolant as possible.

To track down bad grounds, try measuring the coolant's voltage while turning electrical accessories on and off one at a time. A change in the coolant's voltage reading may indicate the accessory (radio, fog lights, etc.) needs its grounding point cleaned, replaced or relocated.

Philip's 1990 Buick Reatta
Philip's 1990 Buick Reatta

In October 2019, I got this Buick Reatta which ran but was in need of some TLC. I am a huge Buick fan but had never heard of the Reatta, so when I came across one, I had to have one of my own. I wanted to find an inexpensive example that had some problems I could fix myself, and was not a museum piece so I would not feel bad about driving it frequently (which I now do). This one fit the bill perfectly.

I have since repaired most of those issues with parts from RockAuto. Some of the parts include an alternator, wheel bearings, intake manifold gasket set, oil pan and transmission pan gasket and filter, camshaft position sensor and I am pretty sure plenty of other odds and ends.

Thank You!
