The thermostat you installed was either bad or is installed upside down. Possibly a clogged heater core. Possibly the system needs bleeding.AnswerCould be your control cable is broken. Not familiar with your particular model but look for a cable on or near the firewall near the heater core. You may be able to move it by hand and get the haet you need. AnswerRemove DEX coolant the manufacturer recommends. DEX clogs the heater core. Put regular coolant in it then drive, drive, drive. It will break loose. Mine took nearly 4 months to get the sludge out of the radiator even after flush. But it worked. Manufacturer will never comment about that DEX crap.
I have a 98 and I had the same problem..it was my heater core, they arent hard to replace and I dont think they are that expensive
Instantly. If someone is telling you otherwise, they're blowing smoke.
a new heater core
i think that it is determined by the position of the sun. cheers-rhys stannard 10DL
Purg The Air Out of the Cooling system
you have an airlock
Thermostat messed up, Oil needs to be changed, no antifreeze in the radiator, radiator fan is not working properly
I suspect that either your thermostat is plugged with debris from the radiator change or that the thermostat was replaced backwards. The spring side should be towards the block.
the ac stoped working and so did the heat . I changed the thermostat added freant
If it is leaking coolant. And you changed the thermostat. I would then move to this section. Flush the radiator and the heater core. This can be done at a certified shop with a reliable mechanic.
by your blowing
Mine used to used up at idle. I changed the coolant but it kept doing it. I am pretty sure it was the thermostat. The best internet advice is that it is probably your thermostat. You can roll the dice and change it out youself or go to a good mechanic and he'll tell you for sure what is wrong.
Simple answer...yes. Not much changed between the years until 81.
