For the past few days I 've noticed my coolant temps higher than usual but figured it was the much hotter temperatures we've been seeing...but today.....
Today .....I'm cruising at 75 mph in sixth gear and the coolant temps are 207 degrees..(usually 192 degrees)
I turn off the a/c and put the defroster on heat.....and it brings the temps down to 198 degrees..
I'm thinking since I put the stock air box on saturday and found out my aftermarket coupling to the maf was letting some air in...I'd run the stock air box for a few days and sure enough the cars running much much better...but hotter...
So this afternoon I put the aftermarket air filter back in and thought....that would resolve the issue...
Low and behold in 15 minutes of around the town driving...
The car is running 243 or 249 degrees coolant...so I quickly turn off the road onto a side street...turn the car off...and park....turn the key just for a D. I .C reading of coolant about 5 minutes later and the D. I. C says....253 degrees...
I'm like holly ****..so
Wait ten to 20 minutes...start the car and then the coolant goes down about 2 degrees every few minutes..
Now the car seems to be running about 217 to 230 degreess for the most part..sometimes down to 208 degrees but the car really used to run 190 degrees pretty much all the time except maybe bumper to bumper traffic..
I could let the car idle now and it settles in at 208 degrees...and then if I drive it rather gently it climbs to 221 degrees..drive it a little harder and the temps climb to 230...
I didn't sit in traffic today so I'm dumbfounded...
No codes in D. I . C either....
Could it be a fuse for the fan blown..(the passenger side one seems to work...I can't see the driverside one so I can't tell.)
Could it be a slipping water pump belt?
Could it be a bad thermostat?
Could it be the water pump?
Could it be worse like a head gasket?
Could it be the tuning? (found the maf connector to air filter was leaking air in...and fixed it...)
What do you guys think? Any insight would be appreciated...
