Hello, I drive a 92 super exceed. I am looking for a cold weather thermostat. It has been -30 here for a while, and the engine does not get up to temp. Please advise.

Thank you, from Winnipeg

hi, you need a new thermosthat, also check you coolant mixture. better put chrysler green coolant mix with 60/40 or 70/30 mix . meaning 70 percent antifreeze & 30 % water max . change thermostat will help you.

Hello, Mardy, thank you. Now, does the van have a thermostat installed already, from Japan? Like a summer thermostat? I have a line on one, but I need it to be rated for cold weather. A winter thermostat. How can I tell?

Thank you,

Winter or summer, wouldn't a properly functioning thermostat keep closed intil the engine is up to opening temp? Ie, isn't it's job to keep the engine at proper op temp, regardless of whether it's too hot or too cold outside?

I was thinking the same thing myself, blocking part of the rad is a good idea in very cold temp though, I have heard that putting cardboard and the like right on the rad with out support (like a grill) can result in the rad getting bent or broken under the wind pressure, not sure if that is urban legend type crap or not.

If you install an OEM japanese thermostat it should still be getting heat without any problems . If it has a north american cross referenced thermostat (which we have had many problems with) then change it for the correct thermostat to check it is not by-passing . Also depending on who installed it , I know of at least one shop that insist on drilling holes into the thermostat to prevent engine overheating !!!!!!

hi, we only used one type of thermosthat either for summer or winter its has 82degree.
never have any problem with this.
hope this help:

The `Stant` brand of thermostats are giving problems by either sticking open or closed causing overheating or no heat situations . Our experience as a repair shop dealing with these vehicles for nearly four years is that the only reliable one to use is an OEM japanese direct thermostat. The NA thermostats even look different from the JDM ones.
