been heavily weighing that option, being that most people end up going this route when the aux fan starts acting up. id like to exhaust all my options before i start to drill the fire wall and add a switch tho.

its started to over heat while stuck in traffic the other day, and started to boil the coolant. since then ive been testing via driveway idle. when i drive, it drops to 170-190 range. now the main focus is the AUX fan. being in the desert i need it for my ac and for when i get stuck in traffic and the desert starts baking my engine. daylights about to be coming, so ima get back at it today.

It sat for four years and we got it running last year. I just acquired it and have been fixing the stuff they neglected. They just got it running and abused it. They did change the tstat last year, as I just called them and asked. Losing daylight, so ima check that and switches tomorrow. There are three(?) switches that could be problematic? Which would be most likely culprit? Hornbrod yes i did. Fan is strong. Thanks so much everyone for the help thus far.

Ok so new lid fixed the boiling issue. It's still running warmer than it was but it's sitting at 210 which from what I've read is not bad. Tho the aux fan still is not kicking on, even when it spiked to 225~ and still does not kick on with the ac.

its reading 210 on my cluster and boiling out the pressure tank. about to swap the lid to make sure its holding pressure to keep it from boiling (though the lid still feels like it fits snug.) . at 210 it starts to build so much pressure it started leaking out the pressure tank. I tested the fan via dc battery. just changed the water pump(and can feel flow through the hoses when on and running)i have to check to see if the tstat is good. and am about to do a flush since the truck sat for four years and ive been trying to bring her back to life.

I have an 87 4.0 that is having over heating issues. the aux fan isnt coming on, with ac or not. I have replaced the relay and socket, checked the the electric cooling fan connector. on top of that my coolant is boiling at just under 210. seals and everything are solid, just had it compression tested and some minor things fixed. thinking of wiring a bypass for the electric fan, but would prefer to stay away from that route. anything else i should check before I make the jump and bypass it? I'm not too mechanically inclined, and this truck has been teaching me allot. any help would be greatly appreciated.

I'm willing to drive to MO but ill gladly cover freight shipping if it is possible. what kind of shell is it?

Looking for a camper top for my 87 LB comanche. open to whatever may fit. Currently in Las Vegas, but moving to CO in 10 days. Willing to do some traveling for it. Thanks all.
