All,
New 1974 car to us, been sittin' for a couple of years with minimal use. Pump was replaced but few miles since. No more than about 10-12K. I want to refit the heater hoses and such. Keeping this out of the engine "fluids" section cuz we can just talk rubber parts replacements. She's been a bad car so far....hopefully can resolve her issues and change her name to Susan soon!*(days of our lives ref...)
Radiator replaced/rebuilt by Hall by second to last owner...again 10-12K on it, 10 years back. Front Pipes look to have been repainted at that time also.
If you know me, you know I tell good-n-long stories and type the same....so bear with me.....!
To get this all started, ...started last week when wife and I tried to bring the car home from our shop about 53 miles away. (for the first time out since rebuilding the brakes after purchasing the car) We made it a mile or so....belt had been squealing on and off....hoped for more off....until finally heard a little "thump" near my elbow and I watched my AMP gauge register a large discharge....."Crap...blew a belt"..... So back to the shop....but not before the car started to overheat.....that last 1/4 mile had pucker factor on high......!!!!
Cooled it down, called a local member about what tank is what.....of course my shop manual is at home....and I'm not! Filled up with water and put it away in the shop.
Retrieved car with trailer last Sat. No incidents to report until after about an hour of sitting in the driveway, wife called me (I was returning trailer) to tell me that the emergency lights were flashing! CRAP! Blew the E-flasher switch.....and I wasn't even near the car. Advised to use "toothpick fix"...only to hear "we have no toothpicks!" Ugh. I have some in the truck.... She tried taping it etc....didn't work. Tooth pick worked, popped out later..... still in driveway.
I will admit that I touched the switch when I was in the car the couple nights before, in the shop, before I started it....and it took a couple of stabs with the finger before they shut off. I guess the heat from the sun took care of it......
Will need to look at switch yet......not now.
Have spent the last couple of days reading stickies, looking for this and that in the car, but can't find out some important bits.
Ordered two new belts, one for spare. Don't make Greenstripe belts small enuf.... (needed 11AV1030 or 40 but all the parts store had was longer..or way shorter..and their belt stretcher was broken...)
Pulleys are all in alignment, alternator turns over well, water pump not funky. Probably neglect led to this failure. Gatorback belts should be here by weeks end. Ordered two.
I have determined that the heater water shut off valve is stuck. Needs the Mike Daily overhaul! On the list... (Thanks to Mike for this info!!!) He spec'd 5/8" ID hoses for replacement! Mine in car are 3/4")
I want to replace most if not all of the rubber heater hoses. Most of the large 1-3/8 hoses appear to be Greenstripe already except for the one hose piece connecting the lower pipe to the pump inlet pipe. Looks like 1.5" hose smashed down to fit 1-3/8 pipe!!! What's up with that!? Deal with that later too....I have more greenstripe hose to use....left over from Goose adventures!
So the heater hoses look to be Motorcraft brand hose, but with a 092793 date stamped into them... I see notes in the owner records about replacing heater hoses, but now wonder "which heater hoses"? The ones up at the console? or the engine hoses????? 1993 is ......24 years back...... Still nice and supple, BUT if you pinch them, you can hear cracking....from whatever is coating the hoses internally....sounds like time for new clean hose!
BUT.....what size hose do I need? I appear to have 5/8" hose in some places and 3/4" in others!?? I checked the hose tubes coming up out of the console and found that they measured just larger than 11/16" (18mm) but not yet a full 3/4" but the heater valve fittings and the heater core fitting look to be more like 5/8".
At the lower section of the engine the pipes would/could/should be the same 11/16-ish (18mm) as observed in the cabin...but the engine water pump fitting is certainly 5/8".....not so sure about the vertical block fitting! I hope it is 5/8".
OK, pause for some math.... 18mm=.710" 3/4=.750" or a mere spark plug gap .040" larger...to squish down to 18mm BUT .125" (1/8") to squash down to 5/8=.625" which is .085" smaller than 18mm....so need to stretch the 5/8" a tad over 1/16" (.625") to fit the 18mm parts.
So far I have the following fittings:
Two engine- 5/8" hopefully on both
Four heater pipe tubes- 18mm
Water valve-one connection- .600" (unknown size in orig post)
Heater core end- one connection- .625" (unknown size in orig post)
*** 2-4 fittings unknown- Expansion tank to radiator????
I have no idea how this hose gets to the front or back.....all one long piece of hose, or more intermediate metal piping and two pieces of hose????? Size of ends?
I'm thinking better to stretch a little bit than it is to try and crush a hose to get smaller......
Anyone have a heater valve and or heater core fitting handy to check sizes? (edit 9/21 OK, did this today....recorded above.)
I haven't popped my system open yet to drain it.....keep in mind that wife has never ridden in car yet....so as soon as belts arrive, I would like to take her for a good spin!!!! She needs to get her "zoom zoom" on......then she'll be happy for a while.......while I dismantle the entire car....!
Has anyone used the whiz bang blue "5/8" ID SILICONE 4-PLY HIGH-TEMP MIL-SPEC COOLANT HEATER HOSE PUROSIL SAE J20 R1" hose in their cars? This crap is expensive (About $40 for 12'shipped) but looks like it would handle bends well just no sharp burs on your pipes or fittings!!!! Sand them down.....if in doubt! Would probably outlast me....!
Years ago, one could purchase the cast iron water pump rotor with the solid vanes ala Boss 302 and such. Has anyone seen where these are available anywhere?
I also used to see round discs that one could DIY this same effect by pop riveting the disc to the rear of the steel vanes of a standard rotor... anyone seen these? Would be easy enuf to fab....next time the water pump goes out! I was gonna take it out thinking that the timing chain surely needs to be replaced...but with less than 2 degrees of crank movement, me thinks that someone put in a dual roller chain somewhere along the way!!!! Now no reason to disturb it!
Ok, enuf for now! Will post other issues in other posts....
Thank-you for reading along!
Steve
