Spring... time to swap thermostats?

I have a CJ7 6 cyl. that has aftermarket air (in fact very durable, amazingly durable aftermarket air)... but there's been a longstanding issue I'd appreciate any suggestions on.

The air puts a strain on the vehicle which has always been relatively temperature-sensitive (gets hot easily) anyway. What's a good temperature thermostat to be using, assuming one's not driving in the arctic, not even the midwest, and will be using the aftermarket air?

Are there any other things that would be helpful to do (or problems to look into) regarding the gets-too-hot-too-easily issue?

Thanks,

CB

Your engine was designed to use one temp thermostat and NONE OTHER. Some guys use lower, but this is basically a high performance mod (sometimes), and has a real downside. If it's a late model, it's like 195* - keep it.

But you can 1) use a "better" t-stat, like a Robertshaw, 2) get a biggger radiator, 3) a better water pump (like a Flowcooler), 4) get an auxiliary oill cooler, or any combination of the above. In truth, the most effective is a bigger/better radiator.

Lowering the temp on the t-state will not keep you from running hot, it just means the system will "turn on" sooner, but once your running warm, the higher t-stat would be full open anyway.

Sorry if this sounds like a rant, but it bothers me that some people (not you) tell others to swap the t-stat when they don't understand what it really does.

OR - just don't use the A/C

Thanks - the Jeep has been sidelines for awhile and I'm now about to get the transmission replaced and put it into more regular use... it's had occasional maintenance, but one of the risks of not using a Jeep all the time is forgetting what work's actually been done on it in the past.

I recall getting a larger radiator some time ago and will check w/my mechanic about the current temp of the thermostat. I appreciate the other suggestions - hope to not have to resort to them, but saved your message to my hard drive for the in-case option.
