Replace your T-Stat and buy XJ-Grin's stroker. Replace the wristpins and you're golden.

The t-stat is basically new - replaced it after I got the MJ from Chris when I tore the cooling system apart while replacing the rotted freeze plugs.

You drove it last winter right? Heat worked ok then?

I can't remember if that system has a heater control valve in-line on one of the heater core hoses....... if it does, make sure that's opening. I never trust the gauge cluster temp gauge in these Jeeps so definitely ensure the actual temp of the coolant is 150.

well see thats the thing is it worked last winter and the gauge was working just a week or so ago in the cold and all went to hell just the other night like say i have never had a problem with my engine to not heat up.

Yeah, if it was heating fine last winter and now cold, the t-stat is stuck open. Swap it out.

what yella said, although he is being charitable only calling those freeze plugs "rotted", they were friggin gone! And,. sorry, my stroker is pending sale... WOOT!... I do have a 258 crank for a stroker build that I could part with though...PM if interested.

 

[YELLAHEEP]

Whut........ THESE freeze plugs? Rotten?

 

[old_man]

was that my 4 banger???

Yup. Coolant use was measured in miles per gallon........

 

[xj-grin]

again, yella is charitable, it was measured in gallons per mile right before we swapped!

dear lord lol and this thing still runs amazing lol no knocks or anything. but so what do you guys think the problem would be then since you know the thing better then i do

 

[xj-grin]

I think the t-stat is stuck open. replace it and be happy. I literally used to drive around with 3-4 gallons of water in the truck, and just pull over every few miles and add water right before the trade (I had to milk a few more miles out of it).
