SOURCE: How much freon to put in the 1990 chevrolet c1500?

As long as you are using gauges, just make sure that the high side pressure is not out of the ballpark high... check cabin temp frequently and depending on ambient temp keep that reasonable as well (134 is not quite as efficient as r12 so don';t look for polar will blow it up before you ever get there.) 210-230 is average high side pressure, if I remember correctly. I've charged hundreds of units and except for very few, I couldn't tell you how much freon was used (unless using a charge station) Just following what I mentioned, I only had a problem with one (had a blocked condenser from the rare i actually remember it) Stay on the conservative side and you will be fine.

I would guess it is metric,as are most all bolts,except some large size chassis bolts,and have been since about 1983. You got rust issues also.

Will 1990 Olds 98 front LH power seat track assembly fit and work in my 1985 Olds 98 power seat assembly, including wiring and cables?

I wouldn't think it would be a direct replacement as they are two different platforms, but I'm sure it can be made to work. I once installed a power bench seat out of a 2004 dodge truck into my 1991 Dodge truck that didn't come with a power seat. Took some wiring and engineering, but turned out nice.

Which is the low side on the ac compressor for a 1990 geo metro?

Is it possible the fittings are the same size because this car takes R12 freon ??
Make sure you are using the right freon and tools.
The low side is on the thicker hose on most cars with R12.

How do I put freon in my 2004 explorer

You can only connect the recharge hose to the low side line(the high side is a different size).The low pressure side of the system will have the larger lines,you will find the recharge fitting somewhere on the lines or one of the components along the way(maybe the accumulator canister).At one time,thet used to put a blue cap on the low side fitting and a red cap on the high side,but not always.(dont count on the fitting to be in a place that's easy to get at).

I have a 2006 Envoy, and it appears to freon is low. I purchased a can of freon from Auto Zone. Tried to put the nipple over the lower valve and it won't connect and snap in. I end up sending freon...

ok, there is a high side, high pressure line, and low side, low pressure line, for your AC. That refill can you purchased has an R134a connector. It will only connect to the low side of teh AC system as they are different sizes. If you try to connect it the best case scenario is what you described, the connector won't lock in place and it sprays every where. The worst case scenario is the can blows up. Make sure you have the can completely connected and the connector locks down or your on the wrong valve and may damage your system or injure yourself.

What is the refrigerant capacity for a 1990 GMC Suburban with rear air

If you're talking about a/c,it can't even be done unless it's by a shop.If your complete a/c has been updated within the last 15 years then it can be done.Pre-1995 used R-12 freon.1995 and after use R-134a freon.The R-12 requires a special permit just to buy,sell,use,or dispose of.The systems are non-compatible.The R-134a may fit the old filler,but it will not provide any cooling whatsoever.Sorry man.Greg

How do I recharge the AC freon on my own?

You should have R12 freon in a 1990 but you can put R134 freon into that system the only problem your going to have is the adapter for R12 is different from R134 after you get the adapter you need to put the freon in the low pressure valve not the high pressure, you will know which one because the adapter only fits the low pressure valve which is located on your AC lines under your hood, theres a little cap thats either blue or black you unscrew. You can't buy r12 anymore because its not good for enviorment so buy R134. you can buy at any parts store for like $5 to $10.
