Looking at the picture at that unbelievable pristine engine compartment ...lol lol....the "return line" hose, left firewall hole goes to the water pump and the "inline" hose, right firewall hole goes underneath the fuel injection plenum eventually to the lower intake manifold, can't quite see.

If they're hooked up in correctly you won''t have any heat and the temp guage reading may be off.

Good Luck ~

yo BRUNO,

87 heater hose routing 5.8efi

"...Reversing the heater core hoses (8) AT THE HEATER CORE will not cause any problems, and may help remove debris from the heater core. To bypass a leaking heater core, disconnect the supply (lower, hot) hose at the engine and the outlet (with T) at the heater core. Loop the hose still attached to the engine back to the open nipple. Set the remaining hose out of the way..."

Thanks Miesk5 I was wondering which one went to the HC and which one went to the WP. I guess it doesnt matter. I suppose it doent matter which WP connection I put the bypass hose on and which WP connection I put the HC line on either.

Cooling System parts question

I was going to use that beautiful engine bay picture to post a parts question but I'm not allowed to create new threads yet. Apologies, as I'm not trying to threadjack. I'm overhauling my cooling system because I just bought a 95 Bronco and the hoses need replacement. One of the hoses has the ends of the line all chewed up from the worm clamps being overtightened at both ends, but the only reference to it in the manual that I see is that it is called the "heater water bypass hose" and has no part number. It attaches right under the overflow tank tube in my car and I guess it's only on E4OD versions. I need to get a new one or replace the tubing on either side. Is there a part number for this? The middle portion of the line is metal and is clamped onto the radiator. Thanks!

Should be just called a bypass hose. There shouldnt be anything permanently attached to the radiator. There should be some lines attached to the tranny going into the radiator for heating purposes , but , they should have threaded fittings .
