Question about 1994 Acura Legend
I replaced the thermostat and checked all the hoses it is loosing a little coolant but not much. my fans wont kick on and my heater blows cold air. when i drive the temp gauge goes from normal to hot and then drops back down.....im stumped!!!!
When bleeding the system to get the air out, you may want to turn of the heater to help get all the air out of the system.

Hi there..... there could be a number of things wrong here. 1st, when you refilled the rad and system with coolant, did you purge the system and get the air out? If not this can cause your no heat and no fan problem because you fan switch is probably not submerged in the coolant therefore not getting the proper temp. to turn on the fans. it can also cause the no heat because the coolant isn't circulating properly.
If you purged the system, then you might have a bad fan switch and thats why it's not turning your fans on. The no heat could be a clog in the heater core.
From What you described in your complaint, it sounds like you have air in the system. I would take the rad cap off and let the engine run and warm up. Allow the thermostat to open and let the coolant circulate. This should help it out.

I had the same problem and it got to the point to where the car was barely even drivable. I changed the radiator, thermostat, and water pump but to no avail. Then i finally broke down and decided to change the head gaskets and that did the trick. An easy way to determine whether or not it is a head gasket is to pull your spark plugs out and see if they are wet. If so then you need to replace your head gasket. Hope this helps

You have a blown head gasket. I'm sorry.
