Ok, so heres my problem. I swapped my thermostat out for a 160 degree one last week. I started the car and it ran like poop, so i swapped the stocker back in. Now the car is acting up. When i start it it goes up to like 2500rmps, then after a few mins it goes from 0-2000rpms until you drive it. It idles at like 1500-2000 until its warm, oh and its definetly taking longer to warm up than usual, and the heat doesnt seem to be working 100% during this time. After 15 mins of driving everything is normal thou. Do you think that when i threw the 160 in that the ECU retarted the timing a little? And now i got the stocker in and the timeing is off? Can the timing be retarted from swapping in a colder thermostat? SNIPER did u experience this? I tried re-setting the ECU and nothing different happend. WTF is going on? someone help a guy out here! Thanks guys.

 

sounds like you might have air in the system. bleed it out and see if that helps.

 

Did your weather recently turn to **** -- maybe drop down to 10 degrees like it did here -- and could that have anything to do with it??

 

Okay, now can i just turn the "bleeder" nut, and then tighten it? I was thinkin about getting my coolant system flushed anyways @ a shop, theyll do it for 35$.




oh and sacs......will running a 160 thermo hurt my car? It tends to run a tad hot after seein 7-8 psi on the highway.....when i slow down it runs pretty hot. So adding the 160 should let the coolant into the rad earlier thus cooling the motor more right? I have heard that the 160 will cause the car to run more rich......this true?

 

That is not true.

 

Doesn't the themostat (it might be another part in the cooling system) have a jiggle valve that releases air (or something like that).

 

nah the thermo has a spring that opens when heated, and allows the coolant to go from the block to the rad so it can cool down.

 

I just looked it up in my book. The book says "A thermostat jiggle valve is a small valve fit into a hole formed in the thermostat. It helps prevent air pockets from forming in the housing." But i don't know if all cars and all thermostats have one.
