Hi all, could anybody tell me what the cooling system capacity of a
2000 Wrangler 4.0L is? I had my radiator leak about a month ago and the dealer replaced it with a new one. The day after I picked it up, I checked under the hood and noticed there was no antifreeze in the overflow reservoir, so I filled it up and drove around and parked my jeep . I checked again later after it had cooled down and it had pulled all the coolant out of the reservoir down to the minimum level. I filled the reservoir up to the maximum level and it has stayed there since. I'm just wondering what the capacity is as I am concerned as to how much colant the dealer did or didn't put in my radiator when they replaced it and if I could have damaged anything by running with the radiator low. My concern is ever since then my temp gauge has been swinging up and down somewhat and will get warmer that it ever used to. The temp gauge used to always be very steady except when it was really hot in the summer and would creep up a bit when idling at stop lights. Now it swings up and down. I am wondering if I may have damaged my thermostat or temp sensor while running with low coolant level. Also wondering if running 100% antifreeze could affect normal running temp. I always see where it says to use 70% antifreeze / water mix. When I filled it I used straight antifreeze. Could this affect things? Any thoughts are most appreciated. The dealer blew me off when I called them regarding not filling the radiator and said I probably just had some air pockets in the system and don't worry about it, but can't help but feel somethings is not right and needs attention. FWIW it has been extremely cold here (low teens) and if anything I would think the Jeep would run a little cooler and not hotter. If I'm crazy tell me so, but any thoughts or suggestions would be most appreciated. Thanks- posted
