does anybody know a company that make bigger condensors for 87 pu to aid in better cooling of the refrigerant?

 

You might try one off of a later model 4Runner or something like that, 4Runners have a larger interior compared to a truck, so the condensor should be bigger, but i don`t know if you could make it work on an older truck though, but it would be worth a try.

 

thanks. i'll look into it.

 

you know, this might be a tad more than u want to do, but why not take the a/c system out of a tacoma (they blow pretty darn cold!) and mcguyver it into yours? when i do my a/c system in my truck i plan on using a condensor and blower from a newer 4runner then rigging it up to mine. (our blowers are WEAK!)

 

The A/C systems blow plenty cold when they are functioning properly.

Try fixing yours first. A larger condensor isn't going to help you

 

x2 - they ran these trucks in some pretty hot countries

 

If it's not cooling to your expectations, my guess is there's blockage/damage to your condenser coil....

 

or....perhaps... your low on freon

 

Like the others have said, You may have some other issues. I would try to clean your condenser with a garden hose & check for proper charge. You may also want to check your fan clutch as well. Do you have the fan shroud in place? On a 110 degree day as long as I'm moving my A/C will blow every bit of 40 degrees from the center vent.

 

some 4Runners had a 'super-cool' option for the condenser, which was a 6 row (or something like that) set of coils in front of the regular condenser. Hoses are a little different so that may be an issue.
That setup would be the ticket to ice in the cab of a pickup, even if you're using HFC-134a.

 

1) I'd check the refrigerant level

2) Check to make sure the fins are clean

3) if both are good, then you may have an internal problem, like a blockage, or just a compressor going out



also, adding an electric fan that kicks on with the AC clutch really helped mine too, while sitting still

 

Hmm... I missed this completely. It doesn't matter much about the efficiency of the compressor or evaporator if the condenser coils can't remove heat to convert the refrigerant back to liquid.
In my house, and every other house, as well as every vehicle I've ever seen, the condenser coils always have more surface area than the evaporator coils: if the condenser can't radiate the heat, the evaporator can't cool.

 

Thanks Abe

You just answered a question that ive always wondered about, my 86 4Runner has that extra 6 row (or what ever) set of coils in front of the regular condensor and i could never figure out why, so now i know what there for.
