Cooling System Thermostat
 

'89 Wrangler 6 cyl. Want to change current one. Seems to have to much drift.
What temp should I get?

Re: Cooling System Thermostat
 

At least 192 or 195.

The hotter the better for interior heat.

Get the standard one (192??) A lower one will not let the engine
warm up to a good operating range for fuel economy. Your '89 has
a temp sensor that should sense full temp and tell the computer
to go to closed loop. IIRC, that sensor kicks in around 160
degrees so you MIGHT be able to use a 180 degree thermostat if
you have some other problems.

Consider doing a full drain, chemical flush agent, power flush,
and refil with new antifreeze. Takes a couple of hours, does
wonders for better cab heat, lower engine temp, etc.

Cheers.

I just bought one for my '85 four weeks ago, and tried to buy a hotter one
(trying to get more heat from the heater), but the standard 195 was all
that was available. With my three-row heavy-duty radiator, too much heat
has never been a problem.

Many will tell you that hotter (195) is better because vaporization is
better.
