    1994 Small v. Big Starter

    I started using a "mini" gear-reduction starter in my 94 Blazer w/ 5.7L TBI engine, and I will never use any other kind. So much easier to work with, and frees up so much space under the truck. Plus, I like the sound of gear-reduction starters ;-) It took a while to figure out the correct...

    cleaning engine and compartment

    Many of the most aggressive cleaners are alkali based (sodium hydroxide, etc). Heed the warning labels. These chemicals can permanently damage paint or aluminum if not promptly rinsed off, not to mention chemical burns to skin or eyes. If alkali degreaser has been soaking on dirty parts, dont...

    Spectra Radiators - Good, Bad, Indifferent??

    In recent years the Spectras have been made in China, not Mexico or North America, and I think the quality has degraded. Two Spectra model #CU624 (2-deep core, for extra cooling) installed on my 94 5.7L TBI engine, and both started leaking at the drain **** within 6 mos. I even tried stacking...

    Remanufactured Jasper NP241 or let local shop rebuild?

    Thanks for all the advice. I decided to install a used transfer case, the total labor + parts is mid-$1100s , and the local shop provides a 90-day parts & labor warranty. The mileage isn't known, but w/ 90-day warranty it shouldn't be too bad. I will keep the old case (no core charge), just in...

    Remanufactured Jasper NP241 or let local shop rebuild?

    1994 K1500 Blazer, 250K miles, led a very gentle life. No towing, no offroading, stock suspension. Last night, truck started making horrible, "grinding gear" noises when I slowly accelerate from a stop. A local mechanic has traced problem to the NP241 transfer case. No external cracks or...

    350 TBI coolant leak @ intake manifold

    '94 350 TBI ... the front corner, passenger side of intake manifold is weeping coolant. Seems the thick silicone/RTV bead may be failing. Engine has about 250K miles and never been opened. 1) It may be weeks before I can get to it ... is there any immediate danger of coolant getting into...

    Lower Radiator Hose Problems

    I've never had any problem with OEM stock hoses. I do clean all around the male barbs with a 'fine" abrasive scotchbrite pad, as it can accumulate crud and corrosion which will cause leaks. The underside of a hose barb is too easy to overlook. Ordinary worm-drive hose clamps won't...

    Replacement Schrader valve cap for fuel rail? Where to find?

    yes, a metal AN-04 cap, easily sourced , seems a better idea. If schrader valve were to leak fuel on a hot engine, the metal cap would prevent it.

    Grease point questions

    NLGI-2 grade from a reputable manufacturer: Chevron, Castrol, Valvoline, etc. No reason at all to use "synthetic" grade. There are precisely 12 zerk fittings on a 4WD vehicle, including the propeller shaft (dont know about 2WD). The zerk on the idler arm assembly is easy to overlook and hard...

    Newb Suburban questions

    "Is there a way to pop the rear glass without having to stick the key in the latch every time?" My 94 K-Blazer started having same problem couple years ago. I dont think it's the gas lift cylinders (but I could be wrong). I suspect it's some weakened spring in the latch mechanism in the lower...

    OE lower control arm solution?

    Like SethT , I also have a 4WD, 1994 K1500 Blazer. With 250K miles, the entire front suspension needs overhaul. Guess I'll go the salvage yard route for lower control arms. Has anyone used the after market-upper CAs, and if so, how was the quality and fit?

    GMT400 vs newer MY2014 & Up

    perhaps off-topic, this seemed to be the least-inappropriate subforum to post in, for now ... My 1994 K1500 Blazer w/ 250K miles is becoming harder to keep in good running order ... lots of smaller & medium issues need more attention, than I have time to deal with. Very disappointed w/ newer...

    Value of our trucks

    "Scarcity" and "Desirability" is what drives high values. 20 yr old Camrys or Corollas may be scarce, but no one especially wants one. My 94 2-door K1500 Blazer has badly failing paint on hood & roof, but about once a month someone will walk up & ask if I want to sell it.

    Delco starter

    Conventional black heat shrink , typically polyolefin (sp?) is fine, you don't need special ultrahigh temperature teflon-based. On the new terminal, don't just crimp-only, do a crimp plus solder for maximum reliability & no corrosion. Factory crimps are gas-tight, machine formed, and can't be...

    Safe to Heli-coil AC bracket to cylinder head?

    What prevents the welding rod from also melting & attaching to the cylinder head, instead of just the broken stud?? The stud is recessed below the surface of cyl head.

    Starter choices

    well, I dont know if the 96 Vortecs use exact same engine block, flex plate, etc, as 94 5.7L TBI ... But here's what works on my 94: Autozone DL9990S mini-starter (gear reduction) 11t pinion, offset mount bolts, for 168t flywheel. Bolts: two GM # 12338064 (3/8”–16 x 4–5/16” under head...

    Best Lube for Door Hinges?

    Same here, I use it on all hinges and for many general purpose shop applications. Aerosol will penetrate, the volatiles evaporate, leaving behind a light-bodied grease.

    Help finding leak from rain

    I notice many are intending to use silicone sealants. JMO, but I really dislike silicon sealants. Why? Because they won't stick to themselves. If you ever need to add more sealant, or remove & reseal, you have to physically abrade off all traces of the old silicone. Urethane-based sealants...

    Help finding leak from rain

    ANYONE - is removing that cover over the cabin's air inlet, just a matter of razor cutting the body seam sealer? Is that a PITA? Seam sealers can be very tough & tenacious. My blower assembly is not leaking water, but I'm thinking to fabricate some type of screen mesh over the air inlet...

    '94 TBI 350 Timing Chain

    Engine (RPO L05) has 250K miles and it's had a gentle life, no towing, runs well & reasonably quiet. Is there any reason to be worried about timing chain & gears? I'm not eager to do it, but is there any value in pre-emptively replacing the parts? I'd hate to have the engine...
