I got the new champion radiator; while filling the system noticed I don't have any heat coming from the heater. Not sure why.
I ran the car for 30+ minutes on the jack stands and temp gauge still maxed out.
Damn... this is getting annoying

Fieros are finnicky to fill. What I've found works best when starting with a dry system:
=>Remove front radiator cap =>Disconnect upper heater core hose =>Remove thermostat if required by engine design =>Fill from engine until coolant rises to level of front radiator cap =>Install front radiator cap =>Continue to fill until coolant rises to level of upper heater core hose =>Reconnect upper heater core hose =>Continue to fill until full at engine =>Install engine coolant fill cap =>Fill front overflow bottle =>Run for 1-2 complete thermal cycles and check level in front overflow bottle

As I've stated before, check the coolant routing for the heater and steam lines and do not assume the previous owner did things correctly.

Following Will's advise.. I seem to have filled and burped the cooling system correctly. I now have heat coming from the heater and the car is running within the range I set the TinyCWA control to. I am still getting incorrect readings from the stock gauge but I'm not over heating like before.
I'll have to trouble shoot this issue a little bit more.

Hello all,
I am still having over heating problems. The car runs great for the first 30-60 minutes depending on weather. Once I hit 205 degrees; I lose power and it runs like crap. During the last outing, I noticed steam coming from the rear vent hose.
I've done the follwoing:
Gutted the stock water pump (LT1) and pulled the thermo stat Added a BMW electric water pump at the lower radiator outlet Added a water pump controller set to 165 degrees Added a new 3 row aluminum champion radiator Added a high flow Volvo electric fan
I purchased a new stock water pump and 160 degree thermo stat. Can I run both at the same time?
My assumption is that since its reverse flow the gulled water pump is not routing correctly.
Any advise would be greatly appreciated.

I posted the above when you wrote that you gutted the stock water pump. I suggest the same still.

160- deg thermostat will not solve anything

Cyrus88- I totally forgot you mentioned this.
OK ...
Any way you can put a parts list together?
If that is not asking too much.[This message has been edited by str8maxn (edited 11-23-2022).]

Oh you won't have any trouble figuring out what parts you need.
Also keep in mind that only a few overheat cycles can warp the heads and lead to head-gasket leaks.

Could I use a T fitting vs. Y fitting (AN fitting) ?
