Starter Replacement and Cooling System Adjustments - The 1947 - Present Chevrolet & GMC Truck Message Board Network

After several years of fighting the heat soak starter issue and years of research, I finally went the route of buying a 1998 Tahoe Starter (AC Delco 337-1022) from Rock Auto. Shout out to all those that have posted about what starter to use. I admit that I was a bit apprehensive, especially after I opened the box. It did require me to purchase longer bolts, but fortunately O'Reilly's had a few in stock. Overall it bolted right up, did not require any shimming and no friends had to be used to hold the thing in place.

Also while messing around, I figured it was time to adjust my electric fans on / off temperatures. Low an behold, I realized that the fan controller had leads that I could hook up to the Sniper. Took a bit to route the wires cleanly and figure out the secret location in the Sniper settings to set things up, but got it done.

With all them projects done, took it out for a test ride to get some serious heat under the hood. Made a few stops along the way and she fired right up each time. Man I love this forum.

A couple years ago, I replaced my 69's full-size starter with an AC Delco 337-1022. I absolutely love that thing! The package and documentation were first rate.

Not sure which GM vehicles mine was meant to fit, but it works just fine on my one-piece main seal 350 block with 168-tooth flexplate. I swear, compared to the big starter, this thing spins the engine over like the spark plugs are removed!

I also had to buy the proper knurled bolts. It's VERY important to use them.

The first time I installed one of the small 1994-99 Chevy truck starters I was skeptical it would crank a low compression small block much less a high compression 454. The 454 was in a 1958 Impala which had the typical heat soak starter problem.

That little permanent magnet gear reduction starter cranked the 454 faster than the old HD starter ever did and completely solved the heat soaked starter issue.
