Fairly new to the Vette community and need to know..
I was driving the other day(live in NJ) local streets and roads..
Everytime I stopped the temp needle kept creeeping up to 210..220...230..
When I started driving it would go down all the way to 190...185..
All this would happen in a span of 2 to 3 minutes..
As long as ikept moving the car was cool..
I have a Vram cold air intake..
Could this be just a coolant issue or something else??
mine did the exact same thing. I put in a new radiator from dewitts (leaking at the bottom corner plastic to metal seal... very very small weep) and replaced the water pump to a ls2 type water pump from gene cully. now its solid as it was when is was new. I did find a serious amount of junk way up top between the radiator core and air conditioning core when I took it apart. I do thing the surge type symptom was the waterpump to be true......... it was rather easy to do, I certainly would not pay a dealer to repace the waterpump.
Sounds pretty normal to me. When it got to about 226 you should have heard the fans come on as long you are driving less than 35.. Both come on at the same time at their low speed at 226 and go off at 219. If the temp gets to 235 both fans come on at high speed and revert to low speed at 226...... If you have the AC on the low speed will come on at a lower temp. I think it was 185 unless you are over 35mph.
If the temp goes down quickly while you are moving I think you have nothing to be concerned about. It's when the temp keeps rising while you are moving that you need to be concerned.
Thanks for the info..
At what temp do I have to be concerned about the car overheating..
Is there a normal range??
Im not sure If the fans came on because the I was playing the radio..
Thanks Again!!
