Here's a strange one-
I was on the way to work, driving along in 5th. I noted that my temp guage was climbing. I remember in my white car the guage was broke, so if I tapped it it would go away, this was not the case here. After a bit, it kept climbing, but I noticed no change in my heat in the car. Generally, when I go into an overheating situation, I will lose heat in the car. Thought this was odd. I revved the engine to about 5k in neutral real quick and when I did, the temp dropped back to norm right away. It didnt creep again, however I thought I smelled antifreeze. I checked when I got to work, no leaks anywhere, nowhere wet. The core hoses, upper and lower rad. hoses, radiator itself, under the core on the floor, nothing. Maybe it was just my imagination, or it squirted out of the overflow tank or something??? On the way home, I was paying attention to my heat, and when the RPMS went up fast, or especially if I was under load (5th at low speeds and stand on the gas) the heat will get cold quickly. After a few seconds at normal RPMs (or no load) the heat returns.
Is this perhaps related to my overheating this morning? What would cause that, just air in the system? I jacked up the front and 'burped' it, and I couldnt get any more air out. I'm not low on coolant. I have a new radiator. I have a new water pump. Only thing I can think of is that under load I have not enough vacuum to keep the valve open and consequently the hot coolant does not reach the core, but wouldn't that do it on all cars then? Also, the core shoudl be hot enough that if I dont have circulating coolant for a few seconds I shouldnt get ice cold air, at least that's what I think. WTF, I'm kind of at a loss.
I'm going out there to look around now (I got off early) and will report any findings, but some suggestions are quite welcome, as I dont think I'm going to see anything I didnt see this morning.
TIA,
Ken
