Does a 99 1.8L require a gasket for the thermostat?

Thanks.

Even cheaper if you buy it from Honda

When I changed my thermostat (OEM), it came with that gasket.

stupid me, i bought the crappy tire thermostat and it didn't come with a gasket. i don't know what i was thinking. i'm going to return it and buy a HOP thermostat and gasket.

trenell, what's the difference between the 19975 and the 19301 thermostat?

and is the 99 SIR thermostat compatible? ....at honda, it's like $40.00

No difference, that site just has weird part numbers. If you look around they have basically two part numbers for everything.


Yup the 99 SIR is compatible.

Confirmed. I just installed a 99 Civic SIR thermostat into my 94 gsr yesterday. It cost $45.00 from honda after tax.

The upper and lower rad hoses from Honda was gonna be about $220.

The upper and lower rad hoses from Canadian Tire were $40. The only difference is that the lower rad hose is about 1" shorter so you have to strech it more and the upper rad hose is too long, gotta cut off 1.5" at the rad connector part. I went with the Canadian Tire hoses.

Overall about $120 for thermostat, upper and lower hoses and two jugs of prestone premixed coolant.
