Thermostat '04 H2

[vandy0090]

hey buddy i had the same issue with mine right after i bought it. get going down the freeway with some rpms to her and the heat would kick on and the temp gauge would go down.. stop at a light and the temp gauge would come up and it would start blowing cold. thermostat is your issue. its the front center twords the top of your block. i belive it was 2 bolts to take the housing off. not hard at all. the new one sits in the housing really well (not like some fords i have) so its easy to align when reinstalling. as far as the occasional fuild under the truck.. let me know if u see anything. i also am gettin that and it started about the same time as the first issue. i was thinking maybe blew out a seal on my water pump. maybe (hopefully) a bad hose. but i hanvt had time to pull the scrape plate and take a look. i cant seem to find anyhting from the top and its beel tricky since it only shows up once a week or so.. but good luck

had the same leak problem with my 03h2, and it was just the water pump seal cost me $19 to re-place. Hope this would help.
