I really doubted a cracked block/head, or 'wrong heads' as his buddy told him could result in overheating at idle but not at cruise rpm- would hate to see him throw more money in the wrong direction...it sure sounds like its not pumping enough water to me- cant imagine radiator contents heating that rapidly at idle...sure sounds to me like his pump aint moving any coolant at idle- suggested he leave cap off to prevent pressure and put some clear tubing on one of his radiator hoses to *maybe* see if anything flowing. something else- he has looped the heater hoses as his heater core started leaking- that couldnt bypass enough at idle to starve a head or something could it?
Anyone got any ideas or heard of any such thing before? Really a shame as this car is a cherry original, perfect everywhere except for this overheating thing. that car has the coolest red leather interior ive ever seen...anyone thats got any advice please share and I'll pass it along.

Re: FE overheating question

You could check the temp gauge with one of these if you don't want to use your wife's meat thermometer.

Amazon.com: Mr. Gasket 2470B Domestic ThermoCap Radiator Cap With A Temperature Guage.: Automotive

Otherwise it looks like an air flow issue. Light up a cigar in front of the radiator and see if the smoke gets sucked in as fast as on your other car.

Re: FE overheating question

what does he consider hot ???

whats the actual temp-- stick a thermometer into the water -- tell us what it reads---

his prob is either abad sending unit-- or one of the head gaskets are on back wards--

if you think it might have an air bubble in addtion to raising the car up as suggested you might try an old racers trick. take your thermostat and drill a 1/8" hole in the outer edge of it. that will allow the air to excape when it's cold and closed. make sure the hole is at the top. it will also allow a very small amount of water to be circulating all the time. may or maynot help but couldn't hurt.

Re: FE overheating question

I have the EXACT same problem….plus lots of moolah involved.
Bought a fresh “422 HP” FE from Tuff Dawg engines of Arizona.
New Aluminum heads. Installed in my ’68 Cougar. From the instant
I started the engine (including the 15 minute break-in run) to this day…
200 miles later, it still is running
between 210’-220’. Frustrated, took to shop where my new Griffen
aluminum radiator was replaced with a MONSTER crossflow one
(so big, they had to move the battery to the trunk). Twin electric
fans with custom shroud also installed. Still running waaaay too hot.
Tuff Dawg suggests stock water pump instead of the high flow I put in.
Switch made…(anyone need a new Edelbrock aluminum hi flow water pump??
.Still no change. (see where the money pit is heading?)
Street Rods Plus of Lodi, CA. (shop I had try to figure this overheating issue
out) thinks maybe backward head gasket…not sure but frustrated also.
I did notice at one time while cruising, the temp dropped to about 190’
hmmmm. I wonder if the poster who says maybe old freeze plug may be
floating around inside the block has a point. At this point I guess I need to
pull engine (one year warranty from Tuff Dawg….hmmmm maybe have to
send it back to them…..more money)….maybe best to pull current freeze plugs out
and rotate on engine stand and hope something rattles around and is accessible to
take out….wish there was a simple solution….

FE overheating question

try a meat thermometer in the rad ,to see temp, and make sure rad cap,has proper pressue,but my 390 failane would run hot,after i took the shroud off, didn't pull enought air from corners,of rad, and if you turn heater on does the gauge drop. bill

FE overheating question

Was is the over-bore on his engine? He may have just gotten too thin. He may want to try an aluminum radiator also as a crutch, but there is something else going on. I wonder if he may have swapped pullies at some point?

Put a new mech gage and see what it says. Old one is probably shorted out.

FE overheating question

Temp unit is in the front on the intake manifold near the distributor. I also think you should get a manual ice pick guage start the car with the cap off and see just how fast it heats up. Something doesn't sound right.

I just can't see it happening.... The gauge sounds to be working properly if it does not show hot while cruising highway speeds... But....

Do have him lift the front of the car when adding coolant though. I cannot think that too little tolerance on the ring gap causing this either, and if it were the Bearings being too tight they would have bveen thumping by now... They would have worn down to the copper already....

The major issue that I see is the Fan Shroud... He needs a proper one or the car WILL heat up in traffic or just sitting, although not nearly as fast as the gauge is protraying...

Keep us informed...

I shoulda been more specific- car had only been sitting about 1/2 hour- gage(antique original) showed bottom end of 'normal- but rose VERY rapidly after starting- radiator felt only warm before starting, so dont think it was drawing in hot water- if I'd have been thinking shoulda felt radiator again after he shut it off...)
when I was talking to him it was pretty dark out- I dunno where sending unit is located- assuming from the rapid rise that it would HAVE to be submerged/near combustion chamber/little to no coolant flow. sounded like gage error too, but he said its fine at cruise...other thing I'm not sure of is what machining was done- obviously from him describing ring problem he musta had it bored, hopefully not too thin/dunno if he enlisted any 'porting' help either- even though I kinda think a casting that much too thin would have cracked by now...will probably run into him again saturday, will repeat suggestions for Dye checking/mech gage/jacking to remove bubbles/shroud...hopefully he'll already have figured something out, but as its been months/three teardowns already, I think it might be doubtful. Really a shame as its one of the nicest tbirds I've ever seen, and I'm sure he's thrown an awful lot of time and money away the past few months. will let you know- thanks again for all the tips guys!
