Have Classic Car Questions? Ask an Expert.
hi, my name is XXXXX XXXXX I will help you .
first I need to ask a few queastions ..
1) how are you measuring the temp ?
2) how long does it take from first starting the motor until it reaches over 210 degrees ?
3) have you tried flushing the block ?
The temperature is measured by the guage. It takes approxatmtely 3miles to reach 210. I have not flushed the block.
are the fans running all the time ?.
was the car running the temp the same with out the electric fans ?
do you have a clutch fan in the car now ?
yes the fans run all of the time.
yes it ran the same temp. before the electric fans
no clutch fan
if you have an infered lazor thermometer reader,on the intake measure the temp ,first at the front of the intake near the thermostat and at the back of the intake ,see if there is a difference .It couldnt hurt to flush the block .
can you see the coolant flowing good in the radiator ?
I have a friend that does but it will be a couple of days before he can check it
did this engine have a lot of miles on it or sit for awhile ?
was the coolant /water in the block rust colored ?
Don't know the answers to your questions but will try to find out
if it was sitting or there was rust in the motor ,it may be partially clogged in the rear of the motors water passages ,not enough to block the flow but to that point where it could be blocked .
you can try flushing out the block and see if that helps if not then you may have to remove the soft plugs in the rear of the block and clean it out that way .
there are some good cleaners out there -Gunk brand,.but you will need a heavy duty cleaner ,that will usually do the trick ,you may have to do it twice even .. but I would try that first .
you can also have a block test done to check for hydrocarbons in the coolant ,as for a possible cracks in a head or head gasket , a bad head gasket doent mean that it will smoke out the exhaust,or put oil in the coolant etc.
if that pans out then flush the system ...jazzmaster ..
