Thread: hydramaster CDS 4.7 low heat??? any help

1996 Chev ... HM 4.7CDS .... water temp is only about 95 , I have some other possible related problems . (1) van heater blows out luke warm air, (2) temp gage on van looks like is only heating up to about 150 , The heater core seams to be in good working order so why would the heater/defroster blowing out only slightly worm air? I changed the thermastat in the van but that did not help at all. I think the temp at the wand should be at least 180 or so. what do you all say? Thanks for any help you can give!
