Put a restrictor of some fashion in the hose to the core. Even a flush T would probably be enough. Also, don't cheap out on a good flush and new coolant.

There's been plenty of cooling system issues with this car over the years. It tends to like to bust every hose, part, HEATER CORE I put in it.
Thought it was solved with a new lower test rad cap (13 lb I think it is) and it was good for a couple years. Coolant is nice an clean due to always having fresh stuff in it, and it does be flushed every time it's opened up for surgery.
Alas, I'm getting good at replacing heater cores now...Summer car-> 1988 Lincoln Town Car, triple blue, 335,xxx km. New HO 5.0 in and running. Bought 2006/08/22. June 2017 PotM!

As for your issues, it sounds like there is a restriction somewhere in the coolant system that is causing pressure problems. Changing the rad cap to a lower pressure is a stop gap fix but something else is happening. Thermostat good??

still popping with a 13# cap? interesting. maybe the radiator neck is too short for the cap? You shouldn't have to press down on the cap much to get it to engage with the radiator fill neck. If you're having to lean into it to get it to seat initially, you may need to find a shorter one.

Upper rad hose gets nice and firm but nothing abnormal. Stuff goes keblewy when I accelerate either bit hard at all, such as when I'm pulling out into traffic or if I'm passing a slower moving vehicle on the highway. Maybe my water pump is too enthusiastic? I thought I had it cured with the rad cap. Oh well, in any event I need to find a new heater core. I'd like to get a NOS Ford/Motorcraft piece to eliminate the aftermarket brand variable. Anyone know where to find such a beast? I already checked the local Ford dealer here, they don't like dealing with anything over 10 years old. I checked fordparts.com, they got nothing and Rock Auto is all aftermarket stuff.Summer car-> 1988 Lincoln Town Car, triple blue, 335,xxx km. New HO 5.0 in and running. Bought 2006/08/22.

My Autozone heater core is doing well, just over a year since I put it in.
Unrelated to the question of best heater core:
I was at the JY last weekend and found a correction for step 8 on the driver's side section.
On the last picture you can see a hole in the plastic panel where a christmas-tree clip should be. My car did not have this, my guess is when the PO hacked up the stoplamp switch wiring that clip was not put back.
The below pic shows where the clip will be, indicated by the green circle.

Maybe you have a high volume water pump? I'd much rather blow a hose than a core with a restrictor in line.

As for blowing hoses, well, she likes to do that too from time to time.
Winter is making a bit of a re-appearance in these parts, back to below freezing temps again and respectable snow flurries, so it's all on the shelf again until the weather warms up.Summer car-> 1988 Lincoln Town Car, triple blue, 335,xxx km.

Quick question: do any of ye know off hand which heater hose feeds the heater core, and which one is the return line?
I'm thinking the hose from the water pump to the heater core (right/passenger side hose, with thermal blower lockout switch) is the feed line and the other one going to the steel line under the upper intake manifold and on forward to the coolant temperature sensor is the return line. I could take hoses off and see for myself, but meh, that will likely make a big mess. Trying to get the nerve up to undertake this job again....gets worse each time I think!Summer car-> 1988 Lincoln Town Car, triple blue, 335,xxx km. New HO 5.0 in and running. Bought 2006/08/22.
