NO HEAT....Hello everyone!!! i have a 99 ram 1500 sport 4x4....318..... i have had the whole system backflushed, t- stat changed to oem 175 then a 195. i have some heat when under a load... but not much such as plowing thats all i use it for. also a new cap. the water circulates, but does not get hot(can keep my finger in it,lol) no leaks no strange sounds,and have even parked on about a 70 to 80 degree hill and had the cap off while doing this...and still no HEAT. have blocked off the rad also with cardboard and it stays about the same.is there a valve or censer im not finding? tyvm every one for any info.
