car will no warm up

[matt4pl]

ok, so my car wont warm up until i drive it for at least half an hour before the needle moves at all, its winter here, and near or below freezing now, and the car would warm up fine when it was around 40ish, i replace the thermostat last march, and that worked but im not sure if its that now, what else can cause my car to not warm up?

gotta be the thermo. that's the only other thing that's keeping the fluid from your engine from getting pushed around to the rad. it might be stuck in the open position perhaps because of frost? Only other thing that I can think of is that the air around your engine is so cold that when your fans pull air in, the air is cold enough to lengthen the time of warm up.

whats your coolant to water percentage?

[matt4pl]

its a premixed collant, Peak antifreeze/coolant, so its 50/50 i believe

then I would also say you have a hanging open t-stat as well. only point in the system to restirict the flow for warm up.

i figured as much, thanks for the help, now i get to work on my car in freezing weather, im probobly gonna do this on friday, so any help on how to prevent it from staying open this time? any way to check if its faulty once i get it out(i doubt it, but who knows)

Thanks,Matt
