soarer479 Posted August 8, 2004 Share Posted August 8, 2004 we just flushed and replaced my dads radiator fluid on his 95 sc 400 the other day along with his thermostat then once he drove it a short distance and got on it a little bit it started to over heat. there is a small constant noise coming from around the water pump area. we changed his fluid and thermostat ourselves. is it possibly a water pump problem?? it has about 76k on it and the service records dont show a timing belt or water pump change any help would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
johnny3 Posted August 9, 2004 Share Posted August 9, 2004 Make sure you didn't get the thermostst turned upside down & there's no air that needs bleeding out. Quote Link to comment Share on other sites More sharing options...
JPI Posted August 11, 2004 Share Posted August 11, 2004 On the V8 engine you will need to fill the coolant at the coolant pipe neck. You will need a 17mm socket, break that lose and fill it up from there. Otherwise air pocket will form and your vehicle will overheat.

BMAN1113 Posted August 14, 2004 Share Posted August 14, 2004 Thermostats are also one of those cheap parts that has been known to be defective right off the shelf. It only takes a couple of minutes to fire up a pot of water. Drop in the thermostat and track the water temp with an inserted thermometer. Make sure it opens when its supposed to. Then again, if you have a sound coming from around the water pump it may be shot. But usually when a water pump goes, it really goes... as in water on the pavement. Also, you are due for a timing belt change and with that they change the water pump. If you choose to do this make sure that the mechanic changes out the cam seals as well. $1,400.00 (dealer) $750.00 (independant)... ouch!!.... or you could always do it yourself.
