Must-Use Ignition Module Thermal Paste
Vložit

- I replaced the distributor cap and rotor in my 1976 C3 Corvette Stingray a few months ago, and while I was there (famous last words), I took the opportunity to clean the distributor base plate as well as the ignition module and the capacitor.
Unbeknownst to me, the factory recommended the application of "Silicone Grease," in the 1976 Chevrolet Service & Overhaul Manual, amzn.to/3aoi3JL
Since the guys behind the counter at two auto parts stores I visited looked at me like I was speaking in tongues when I asked about Silicone Grease, a quick search online said the dielectric grease was the same thing.
Well, maybe not the EXACT same thing.
After an hour or so of deeper online research, I learned that a far better compound for heat conductivity between the ignition module and the distributor's base, which acts as a heat sink, was to use the same kind of thermal paste as used on computers, and the product with the better reviews was Arctic MX-2 Thermal Compound.
You can also use Arctic Premium MX-4 Paste or Arctic Ultimate MX-6 Paste, which probably is the best option.
I applied the paste as shown in the video, and I've only run the car at idle speed for about 15 minutes since I'm in the process of replacing the radiator, so I don't have any real-world comments as far as noticing anything different. Having said that, sometimes that is the best outcome one can hope for. Besides, as long as the ignition module is cool, then so am I.
By the way, the only "service" possible when it comes to this solid-state component, is to replace it. I have provided a link to a professional ACDelco replacement unit below. They are not expensive so if yours is faulty, you may want to go ahead and order a new one and use a thermal paste like the one mentioned here.
Thank you for watching! 🙂👍🏻

Thank you for this great video. I bought the exact same paste, and I am using it as I replace my old ignition module on my 78 Corvette.
Glad to hear you found the video helpful. Thank you for watching! 😊👍🏻
This is one of the main parts which leave a GM motorist stranded. Left me stranded 3 times. Even with the paste, these are prone to failure due to heat. They get very hot!. I keep an extra one in the car. Most importantly, keep a screw driver and change the mounting screws to the rotor and module to flat head or you will need to carry a box screw driver, phillips screwdriver and flathead screw driver; which ever ones are fastening the parts that need removing.
I unplug only the passenger side of the cap and tilt the cap over; labeling the wires on the passenger side prior to removal.
Good idea on the thermal paste. I do have a jug of dielectric but your paste may have more heat sink properties. As for the actual module, they don't make them like they used to. OEM still comes from who knows where. I bought a OEM GM as a spare but I still have a early 80's module still in the car working perfectly. I trust the old stuff.
P.S. when I remove the rotor any time, I usually lubricate the advance springs to be sure they move freely. A squirt of WD 40...
Good thinking about replacing the module screws because no one has the right size nut driver when you need one. I thought about spraying something on the advance assembly but didn't want to risk any arcing, so I left it dry. Is WD-40 a conductor of electricity? I'll have to research that, but it's a good tip to keep in mind. Thanks!
@@76vette No problemos! Actually WD40 displaces water. It's been an ancient trick by mechanics for wet electronics. I remember my brother getting his HEI distributor soaked after a storm. Wouldn't start for nothing. Apparently he didn't know "the trick". Douse the internals and externals with WD40 and it started right up.
@@aboutmyfathersbusiness8324 Forgot about that... WD stands for Water Displacement, and a little research confirms that it’s an insulator, so no conductivity issues. Fantastic! Great invention along with duct tape and sliced bread. Thanks again! 😊👍🏻
Doing this to a Honda today; thank you for the video!
Thank you for watching! 😊👍🏻
This guy made a heat sink that mounts underneath the distributor and ignitioncontrol module. He said he hasn't had one fail on him since then.
Interesting. Thank you for watching! 😊👍🏻
Nice video. How about the ignition module, is it still running. Did the Artic heat sink compound a good job. No heat problems any more? Was the applied layer enough to conduct the heat?
Thank you! 😊👍🏻 And the heat sink compound has worked great so far. Unfortunately, I have no idea as to how much of the compound is enough, so I probably erred on the side of caution by using a bit more than necessary.
I’m running an accel hei distributor my module just went out what the best brand to replace it with
I’m no expert when it comes to electronics, but I’d recommend staying with the same brand ignition module. amzn.to/3Nr6xzI
Thank you for watching! 😊👍🏻
Why do these ignition modules give out?
Main causes are heat and, especially, the age of the component.
Where can I purchase this paste? Do you have the part number?
This is the one I use. amzn.to/3DFn9l0 😊👍🏻
