I think the thermostat and switch could be bad. It's still the stock one.
Easy enough to test, with the right tools.
I drive the car hard so I want it to be sufficent cooling.
Larger capacity radiator is plenty sufficient for a stock engine.
Heck, the stock setup was sufficient.
Doesn't matter how hard you drive it.
Until something doesn't work right.
I usually always make sure I have been driving for about 10 minutes before I drive the car rough.
Good, don't wanna be hard on a cold engine.
The car is stock. Engine is not modified. Yes, I know what negative effects happen when the engine runs cold. Has about 151,000 miles.
And you are willing to live with the negative effects of running cold?
There are 3 bolts that hold it together. 1 on top right. 2 on left side.
2 hold it together. The third one is for ground wires.
I was able to get the 1 top and 1st left side one out easily.
The bottom left side #18 is the one that is stuck.
Put the other one back in before jacking on the stuck one.Try a little penetrating oil
a little heat
While turning it.
Twist sockets are incredible tools, if there is enough meat left for it to grab on to: http://www.autoserviceprofessional.c...st-socket-sets http://www.matcotools.com/catalog/pr...-TWIST-SOCKET/
beating on the head of the bolt
beating on the side of the housing where the threads are
slice a slot in the head of the bolt for a screwdriver
chop the head off, slide the housing off, then deal with the stuck bolt
I think my thermostat is stuck because it never goes up at all. Even when my radiator cracked, nothing happened.
How about a bad temp sender or gauge
how about it never lost enough coolant to get hot
You can waste a lot of money firing the parts cannon and never fix it.
All this stuff can be checked, much of it quite easily.
Test, don't guess.
