Engine temp too low and no heat

Ok well its starting to get cold out and I wanna try and fix this before its too cold to work outside

Recently my engine has not being getting up to temp. it stays at the 1st dash between 110 and 210 in return the oil pressure stays high i guess cause it thinks its still warming up and my heat doesent have any heat to it.
I do have a transmission cooler installed, not sure if its related

any idea where to start? Thanks

replace thermostat, and flush coolant, coolant thats too strong won't heat up well either. and while you're at it, flush the heater core to.

X2 on replacing the thermostat and make darned sure to only install a 195 degree thermostat as specified for our TJs. That will keep the computer happy which is programmed around that thermostat temperature.

I believe there maybe one on Stu Olsen site. But it's to change out the radiator and the T-state.

Are you looking to do a flush "recommended in your case".

Or just change the t-state? Either one is pretty simple.

Though that writeup says to note the thermostat's orientation before installing the new one, it would have been better to say to position the new thermostat with any hole it may have near the flange at the very top. That hole assists with getting trapped air out of the cooling system so it's important that it be positioned at the top. Personally, if the thermostat I buy doesn't have that hole, I drill a 1/8" hole into it near the flange so any trapped air can bleed past the thermostat.
