How to fix thermostat on 2001 daewoo nubira
Locate upper radiator hose.It will attach to the top or front of your engine block via thermostat housing.Remove hose from thermostat housing,catch coolent accordingly. Then remove thermostat housing, usually two or three bolts. If housing does not come off easy you may try an jiggle it loose, if no luck get a flathead and pry it off, there may be a thermostat housing gasket, or possibly simple RTV silicone gasket maker. Once housing is off pull thermostat out. Noting it's position, mostthermostats have a small dimple of hole indicating upwards position. Once removed use razor blade to remove old gasket and or RTV.If it's a paper gasket, buy a new gasket with your new thermostat. (some thermostats come with gaskets, others dont). Also while at the parts store pick up a tube of silicone RTV black gasket maker.Now! Once everything is cleaned, mock up the gasket with the housing so you know proper placement. open gasket maker, lay a 2mm bead (read packaging to confirm bead) along the gasket on bock sides leaving no open parts, leave the bead, don't spread it around with your finger. Ok now put thermostat in block, then gasket and housing. Try and install it one swift motion without making a mess. You do not want that RTV to leak out the sides and be all messy!Torque both housing bolts to factory spec. I you don't know spec call autozone, or just tighten them to your liking. Not to tight.Crack open a miller light and wait for RTV to set up. When set up( again read packaging) then install radiator hose. And clamp it down, not to tight, the clamp may puncture the hose if swollen or old.Now, tour good to go, but you may need to bleed air out the system, I suggest taking it to a jiffy lube or shop n asking them to do it real quick, or just ask another question on here and I'll explain!Good luck.
