🚗 Enhance Your Vehicle's Performance with Motorcraft DY861 Glow Plug Switch Review

Purchased and installed Feb 2017 to replace a suspect device that was 18 years old. Fast forward to February 2019 and that's bad. You should have left the old one alone. I bought another one as my mechanic said they were the best on the market, but I was very disappointed that they only lasted 2 years, warranty or not.

Installed and worked great on day one. The next day I smelled something hot and smoke was coming out from under the hood. Luckily nothing caught fire. Replaced by aftermarket from O'reillys, all is good. Maybe it was just defective because I always thought a motor boat would be a better substitute. The money was returned on time so no complaints.

The part was almost identical in shape to the standard. The only difference I noticed was that the original said "Made in USA" while this part said "Made in Mexico". While this part fixed the problem I was having with the car, I can't verify how long it will continue to function properly. The original part failed at 65,000 miles after 16 years. Everything is fine at the moment.

ATTENTION BUYERS! LOW QUALITY! I installed 3 of these last year. Luckily I know how to install them myself, otherwise I'd be paying a mechanic all the time. They were under warranty, but the fact that the first two failed under warranty shows how poor the quality is. Tried to contact Motorcraft - apparently customer service is low on their priority list because they don't provide contact information anywhere. The only email address I could find was from another Motorcraft department and they…

Bought and installed due to cold weather starting problems. Well that never fixed the problem and I assumed there was something else going on with my truck. I checked today and it's not working, looks like the relay is energized when voltage is applied to the coil but no voltage is applied to the glow plugs. I bought a cigarette lighter voltage reader and a USB charger and it became clear that the glow plugs are not interacting with this relay. I manually jumpered the main relay terminals and…

I put one in my 2002 7.3 liter F-350 and it failed in less than two years and 10,000 miles. I replaced it with a White Rodgers 586-902 with 200 amp contact rating. I don't know the DY861's wattage rating, but I've seen photos of the pins in one of them and I doubt it could be rated anywhere near 200 amps. You can find White Rodgers 586-902 at Revain for about $25 more than the DY861 and cheaper elsewhere. Note: The White Rodgers is larger than a Motorcraft piece and is slightly more difficult…

I took a closer look and decided on a Motocraft part. There were cheaper glow plug relays and more expensive relays. I used an aftermarket brand on the first solenoid failure about 90,000 miles and three years ago. I chose the Ford brans because they lasted more miles and more years. I was overwhelmed by the overpriced solenoids from the local parts stores and even O'Reilly wanted more for their Motocraft relay. So thank you Raven. There was a heavier option for more money, but the gear was…
