On my truck and I think the Op's(obviously not sure) my issue is getting the engine to warm up.....my heat is consistent...when the engine temp is below the "normal" and near the C the heat is warm(coolant temp about 150F).....once I get the engine to warm up the heat works great....The issue I have is getting my engine to warm up.....it takes along time. i.e. If it is 15F outside and I start my truck and let it idle for 45 minutes the temp will not go above 150F .....and as far as I can tell.......my tstat is working and I do not have any coolant bypassing the tstat......the upper hose is cold for a while..
