Need the pu Depending on application may need the pump for AC doors or cruise. Unsure if a GM diesel was made with vacuum power brakes but that's another one.- fast 99

No, never, especially on duals. Sounds like you need to buy a different set of tires.- fast 99

Factory smoke
Hooking up a battery backwards can cause all sorts of electrical gremlins. Yes, it's possible damage was done to either the wiring or gauge itself. -
NAPA Power Steering Pump?
Usually Rock auto has a good selection with known brands but not this time. Just looked they have lars and BBB whoever they are and Cardone. Provided you're not doing damage by pounding on the pully I would buy a seal and be done with it. Been dealing with this crap for at least 20 years. Much...- fast 99

Dex 3, Dex 6 or Dex Merc all will work. Of course, Dex 6 is synthetic and take heat better without breakdown.- fast 99

To me that appears to be a broken off mechanical sensor bulb. I believe the original sensor will fit the larger diameter hole.- fast 99

What size crush washers for front caliper banjo bolt?
Best to replace with new but I have reused them provided they go on the same side and not turned over. Of course, clean surfaces. Visual match will work, I have a drawer with small brake parts and save any extras. Just be sure to check for leaks like anyone should do after a repair. -
Tires Plus says my Dually tires are too heavy to balance.
Most balancers have a safety shield of some sort. Maybe it won't clear? Another possibility is just that they don't want to do it. Tires that size [weight] usually take 2 people to mount them on the arbor. Takes some effort. Employees today are lazy, employers are forced to live with it. A...- fast 99

R12 recharge from high side?
Most recycling machines cans are inverted. Refrigerant is dispensed in a manner that won't harm the system. System can be under vacuum and partially charged from both high and low side. Then close high side, start vehicle and complete the refill. Just a faster way of doing the job. -
1973 1500 k20 steering issues caused by hydro boost?
Likely a bad spool valve in box. Do yourself a favor buy a Red Head rebuilt. -
R12 recharge from high side?
System high side will be higher than the bottle. Charge low side only and to be safe upright. Will take longer but no chance of flooding compressor. -
‘87 454 R20 eye watering exhaust w/ windows down
If the exhaust is causing eyes to water, it is due to excess hydrocarbons [HC] unburnt fuel. GM invested a lot of money designing exhaust systems. Using that as a base line [single to dual] is probably the best option. Out the right side behind the rear wheel. Might be a good idea to have a...- fast 99

R4 Compressor Cycling Issues
Generally rapid cycling is caused by low pressure on the suction side. -
Just curious.
Depending on how bad the gasket leaked an exhaust system can hold quite a bit of coolant. Sometimes it takes a while to burn all of it out.- fast 99

Multiple Battery types and the danger of diode damage with modern batteries mixed with Lead Acid and OEM alternators.
I was told by a GM rep that Delco wet batteries were designed to take the higher charging voltage of the 90's up trucks. Don't know if that was true or a sales pitch but we got decent service from them given the severe use. Dual batteries lasted about 2 years, alternators 3-5 years.- fast 99

Valve cover bolts won't stay snug.
About the only thing that worked at all on those for me was RTV. 3/16th bead on gasket, set the cover on head, install the bolts to just barely tight. Come back the next day, do a final tighten. Check again in after a couple heat cycles. Spreader bars help a lot.- fast 99

MrCleans tire machine
First gas station I worked at one of those. Don't think anyone ever used it, know I didn't. Might be good garage art. A Coats 40-40A today is usually less than couple hundred. They are difficult to use with TPMS sensors but can be done if careful.- fast 99

intermittent stall
Open a fuel line after the pump. Usually at the carb. Check pressure by cranking the engine. Should be in the 5-7lb range. If that checks out ok add a fuel hose into a small container. Crank the engine for 20-30 seconds. There should be 8 - 16 oz of fuel. If pump fails either test, replace...- fast 99

Freeze plugs into the block- how to remove?
Very true and I have done just that. Access and labor [customer cost] some circumstances old one stays. Doing jobs by the book in the real world are not always possible.

Has anyone used an Edelbrock Rochester Quadrajet carburetor?
Performance? A properly adjusted Q jet has good drivability and reasonable economy on a GM motor. Would not classify it as a performance product. Never worked with an Edelbrock Q jet but never heard anything bad about them either. If it runs good............ great.- fast 99
