85-305 heater thread

[Freightshaker]

85-305
Got home and got out the temp probes.
It was 33 degrees rain/snow
Each vehicle
I placed a probe in the vent closest to drivers side door and a probe on the line from water pump to heater core against the firewall. Both blowers set to medium. I used a Cooper Atkins srh77a to check the line and vent at the same time. Also used a infrared for the starting block temp.

Scion block was shot with an infra red and was 55 degrees. I guess my wife was out and about today so this has tainted the testing.
I timed from when I let go of key and began checking when the stop watch hit 10 min.
Coolant line was 125
Vent air was 111

The superduty.
Block was 33 (equal to outdoor ambient)
Followed the same procedure
Coolant line 125
Vent 87

I say the superduty caught up pretty good with the scion even having a 22 degree advantage. I was a little inaccurate in my early statements but not by much keep in mind I never measured.

The Works wont destroy the cooling system in these? I like the idea of that as long as its safe.

guy's at are shop do this all the time with no trouble...your flushing just the heater core by un hooking both heater hoses from the motor and flushing with plenty of water with a garden hose...

interesting test... but having a 55* advantage is pretty substantial. Once my truck has its first cold-start of the day, making heat after that, all day long, is a piece of cake. Its only the very first cold start and those first few degrees of engine and coolant temp that are the biggest struggle
