Question about 1993 Ford Econoline

Open Question

Cooling System Hose connections

Have cutoff hose coming from rear/side auxillary heater/AC Blower. Looks like (3) hoses coming out from Aux.Blower to engine compartment. Can't figure out where to connect cutoff 5/8"id hose, other two lead to AC connections. Just finished flushing cooling system but could not locate where someone would have capped off or removed components of cooling system. Could use Cooling system schematic.

SOURCE: where is low side ac hose for recharging located

You will notice the low side has a larger aluminum pipe, and along that pipe you will find the low side port. Anyways you can't connect the low side charging hose to the high side so there is no way you gonna make a mistake on connecting the can to the high side and blowing up the can.LOL

SOURCE: What is the part the goes on the hose for the

I assume that you are talking about the Thermostat Housing. (The plastic thing where the upper radiator hose mounts, along with a heater hose and a bypass hose.) These are bad about cracking and leaking. Dorman makes a replacement assembly for this. The kit comes with the entire assembly, including the thermostat. It should be available at most any parts store.

Blower works no heat on 1999 Ford Taurus


Check the heater hoses that go into the firewall to the heater core, they both should be hot,if only one is hot and the other isn't,then the core is plugged. Remove the hoses at the firewall, buy of hose the same diameter,buy enough length so that you can flush away from the engine compartment, install it on one of the heater core pipes,using a garden hose with a jet sprayer slowly blast water into the hose, until you see clean water coming out from the other pipe. Remove the hose and install it on the other pipe of the heater core and repeat the process,you may have to do it several times to completely unplug it. This is a typical problem with a 3.0, 2 valve taurus,coolant looks brown and rusty. The entire cooling system should be flushed, if it isn't the heater core will plug again.

Auxillary water pump


a great AUX water pump can be added on most vehicles by adding a TEE to the heater hose that feeds your heater core. Although your heater will not be as hot. Assuming that is not an issue.

From the TEE, add a hose to an electric water pump from a HVAC company. There are many and they are designed for hot water and pressure. if it is just pumping you want, then run the output right back to the radiator ( top hose - typically ) and it will be cooled by the radiator.

If you are looking for MORE cooling capacity, then run your AUX water through another radiator or coil of copper someplace convenient, and then back to the radiator. Depending on your needs, make the pump as large as your heat problem demands. remember - if your engine is not running and feeding this type of system, you may starve the AUX pump for water. the engine water pump is priming the AUX pump in this configuration. Good luck , Be cool :)
