Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.

HI RickyGorbett! The first place that I would look is the Fan. Check the Fan Clutch and make sure that it is Engaging. Replace that Thermostat, You could actually have a Clogged Radiator, If you think it might be you will need to Remove the Radiator and take it to a Radiator Shop and Have it Rodded and Dipped. Let me know what you find out! Please Rate my Response, I need all the Help that I can get! Thanks!

SOURCE: Toyota Carina loss of power
lets start with the heating up problem!
replacing the thermostat and relay has nothing to do with it. common causes of heating up are improper valve setting timing, mismatch air-fuel ratio, worn-out piston rings, poor oil flow, poor radiator coolant flow.
i suppose you have changed your car motor oil. recheck if its on the right amount.
loss of power:
loose piston rings (causing insufficient compression: indications fog like smoke), air-fuel ratio incorrect, blockage in air intake.
check also for air on the fuel hoses if you experience often jurking problems regularly clean fuel strainers or filters.
