so is better to just take the thermostat out. no thermostat,, work better

Without a thermostat your car can run to hot or to cool. Coolant does not stay in block long enough to allow engine to get to proper operating temp. Coolant will also not stay in radiator long enough to cool off to proper temp. I advice to always keep one in your engine.

thank you, so it must be the water pump.the fan are on, then temp go up.. and fan goes off. they change the termostat.and still temp go up 210 or more.. advice please.....

On my 1985 z28 the fans come on at about 215-220 then temp drops to about 175 or so then go off. In town it stays up and down but never over around 225 or so. Mine has been this way for the last sixteen years. I recently replaced my water pump due to leaking weep hole and new hoses. Still same thing on hot days in city stop and go traffic. Which engine do you have? And how close does the temp get to the red? (255+). Highway driving mine stays around 170 or so. I consider this normal.

Good point tennisshoes. I was not sure what the actual numbers were suppose to be. Thanks that confirms that mine is operating properly or at least close.

i got the LT1 small chevy block 350, original. the temp will drop but still hot. when the car is runing. 220 the max temp, then drop is that save????? thank you....

On my gauge 220 is in the middle and 250-260 is to hot. So if yours the same then you should be ok. These cars tend to run hotter than most in traffic situations. But if it starts climbing closer to the red then I would be concerned.

thank you, for all the good advise... today they are replacing the distirbutor.. i askk the guy about the thermostha an he sais is inside the water pump????? is that true... thank you ...

thank you jim.. today new distributor and thermostha.. and continue getting hot 225 almost to red zone what it can be.... and fans kiking off....

air dams and air deflectors what are dose??? and where are located. this weeken we will do the flush.... then if continue we will do the timing??? rigth... thank you again...

thank you,, i will look for that.. also i find that the relay for the fan was bab.. and the air dams will help a lot so i will buy the relay and see how it work o maybe put the fan to work at all time???? what you think???? if the fan are working the temp is good.. thank you again it make sense the air dams... the distributor was change because it not go on

yes the deflector is there in good condition, we put the new relay in work, then we shut off the car.fans no working , new relay, we only replace one, is 3 off then, plus ac-compresor... we drive around is fine..shut off , no working??????

so is normal, because go too high to hot,, so i will replace the other too,, and see what happen??? yea we did that turn the ac nothing... it wen up more.. but when the fan are working the temp is normal. i will replace the other 2,, if continue i will put it direct. ohh alsothe ac inside the car you fell cool but the ac is off??? well thank you again you been very helpfull.. i will keep you posted what happen when i replace the other 2 thank you

well i think i will keep the fans direct. replace all the relays and do the same some time it works good,some other time dont work so i decide to put the fans direct so is a good idea?????

I have a question what is the thing under the thermastat I think it has a heater hose hooked up to it
