RPMs went up almost instantly to 5500, was so fast I had to let off before red lines. Temp got into the 220s, so I let up and cruised then temp shot up to 235. I basically coasted another 1 mile to let engine cool, and it came down to 216 before I pulled over. Sure enough there was a wet spot on the overflow hose, no signs of water on ground, or anywhere else. Rest of way home I took it easier and temps ran 208-214. Let it cool down in driveway, and checked while still hot and water level was low by about a quart.
This evening I took it back out on flat roads, not over 4000 rpms up to 80 mph. temp was only 192-203. I watched temp go up 223 while sitting idle, fan kicks on and temp goes back down to 210 before kicking off.
Not sure if I am hitting it too hard and that is why its overheating or what? I want to make sure it will go up steep inclines like today, before taking it up the mountain pass.
I thought something might be odd with the heater. Heat is blowing out top of dashboard, feet, and in rear passenger, but not out any of the front dashboard vents. Wife says, heat has always been that way. Might be normal? |
I forget what year model yours is. On my 98, when you turn it on, it "thinks" for a second to decide whether you need hot or cold air as per your auto-climate control. If you require heat, it sends it out the bottom. If you require cold air, it sends it out the passenger vents on the dash. I think this avoids the "stuffy" feeling. There is a mode button that you can use to override its decision, and to choose your own distribution channel (face, face and feet, feet only, etc).
So I think that's normal.
The temp getting up to 230 then back down to 210 thanks to the fans, is a result of econo-mode. On my 98 there is no Econo mode... just AC, AC OFF. With the climate control system on, I can turn off the AC and it just blows air (Equivalent of Econo mode). Well, with the AC on, the driver side radiator fan comes on automatically so I seldom see any temperature above 213. That's what I was talking about on an earlier post.
Try the same cycle with the normal AC mode on (not econo mode) and your temperatures should be more stable.
