thermostat/ temp guage ?
Hey Ijust realized this is a perfect place to find the answer to something I've wondered about for quite some time now.
If the temp guage moves but just barely and only gets up way below normal, what other than the guage could be wrong? I pulled the themostat and put in a new one. still barely any movement on the guage. except once when a water line broke and it lost coolant. them it climbed up 3/4 of the way before i shut down the engine. Would putting the thermostat backwards do this?? Seems like that wouldn't make much diference
This is on a 92 ford van with a v8
sorry tojump rigs here but I'll bet someone knows anyway

OKAY
I hate to admit this but I never understood howto purge the system of air. My thinking is: if I run the engine awhile with the cap off, any airbubbles will come through and to the top. At least that's all Ive ever done in the past when changing a radiator/ water pumpetc. Straighten me out please
thanks

Sometimes there is a purge valve in the cooling system and with the engine running and hot you slowly crack open the valve until coolant comes out and then close it back up.
If there is no purge valve then you takethe radiator cap off (when cold) and then run the engine until the t-stat opens and watch the coolant level. Make sure that the heater is set to hot and the HVAC fan on low.
As the coolant level drops you add more coolant until it no longer drops.
Then drive the van for a couple of days and check the coolant level again.
Before you purge the system make sure that your overflow tank is full.
That should do the trick.
If the t-stat was in backwards the engine would overheat because the thing that gets hot and makes it open would be on the wrong side and would not get hot enough to open the t-stat.
Hope this answers you questions.
