While driving on a long decline my engine temp went down to near C. I was wondering if that is a major problem that I need to fix. Normally the temp is just below the middle mark. Could it be thermostat or water pump? Please help Thanks

 

its probably your thermostat.........check that out

 

Thanks!

 

no problem man lemme know how it works out

my 89 civic hatch did the same thing, replaced the thermostat and bingo bango it fixed the issue.

good luck

 

Im having the same problem. I swapped out my thermostat, and now it keeps falling. But its weird, cause the parts store told me that 180 was original temp for my 98 EX. I dunno about that. Now thats its been cold out, it doesn't even warm up. Im gonna go and get the 192 temp one and swap it out and see what happens.
