I Have a 93 4 dr civic with the beastly 1.5, ok heres the deal i changed the friggin thermostat and now it won't warm up to its normal operating temp it stays cold for so long. now when i drive for a while it eventually gets warm. When i'm just sitting idleing and i rev it up it gets cold so wtf?! and i get super bad milage. Also i noticed that i had bad milage and it felt sucked out after i got my TB replaced. Engine is just struggling to speed up u think this is a bent valve or what. the mechanic did a compression test and said it was ok but i dunno any ideas any1 this thing is pissing me off. thanks sorry but the story of my life

 

You got the right thermostat, right?

 

It's also possible to install it upside down...

 

Ummm Well this is the funny part i went to Ct and i got all 3 they have i started with a 180 f then it was all wonky so i tried a 170 f weird **** like it wouldn't get warm ever so i thought ok get he 190 so now its in the car now and its not upside down so i dunno what to do now maybe go back to 170?

 

first off, Wonky? thats just a cool *** word. i just smirk everytime i think it. hehe. second, it sounds like your tb is off by a tooth. get it checked. thats probably why it doesnt have any power and bad gas mileage. there is a small hol ein the top of the cam cover, that you can drop a small metal rod, like a nail or allen wrench, into, and it will hold the cam at TDC, then you just line up the TDC mark on the crank pulley. simple.

 

Ya but i changed the thermo back to 170 and it still takes long to warm up and and the temp kinda drops sumtimes what could be the prollem? and the timing belt i dunno what to do there i don't want to take it off and then i can't put it back on again

 

Ne 1 Could it be that i got air in the friggin system cause i even took the rad cap off and let it run for a hour or is there anopther way of making sure?
