Ok so this is interesting. Over the summer I replaced thermostat, both rad hoses, rad, waterpump and t-belt. Didnt notice till today when its like 9F outside, but the heat isnt pushing like it should it seems. Upper rad hose is hot but not so hot I cant hold onto it, lower is cold. I cleared out the cooling system and everything seemed fine this past summer, seemed like no clogs.
Bad t-stat? Water pump cant possibly be bad, I think I woulda overheated. Temp gauge is about a tick mark off from the middle, so I know its getting hot. Perhaps I have the wrong t-stat? It came with the t-belt kit from ebay from aircabin man (the kit everyone seems to buy) and was a denso/toyota part I recall.
Clogged heatercore? Bad waterpump, bad or wrong temp t-stat? Or is it just to damn cold? I stuck some cardboard in front of the rad but didnt seem like it did much.
The truck was fully warmed up just now when I checked all this.
Edited to add: Just removed the cap, damn coolant isnt even hot!!!!! Coolant didnt fly out either like you normally get..ugh I think the rad is clogged...brand freaking new!!!
