Cooling Issue

[ztuned]

hey guys,

my car seems to take ages to heat up after a track day,

basically it takes the car 20 mins to get up to 70 degrees, and just stops there. It use to heat up to and stay at 80 degrees and only take about 5 mins to warm up

ive recently had the water pump replace and coolant flushed, so they def arent the problem

i was told it was the thermostat that is failing? but i just want to confirm before going out and buying one

thanks

yeah sounds like the thermostat isn't closing properly. best to replace it now before the weather heats up because then you may find that it also doesn't open wide enough on a hot day and the car will overheat.

Sounds like the thermostat is stuck fully open, if you pull it out while cold it should be completely closed, it should only be fully open at 76.5c

if it was stuck fully open it would take longer than 20 mins to heat up (depending on driving/location, etc). in my old n14 i had the seal around the hole where the moving part of the thermostat disintegrate and it was only a 2mm gap or so and it was enough to make the car take ages to come up to temp.

I think my thermostat is on its way out aswell. The car is taking forever to warm up and I live in sunny North QLD FFS lol.

I took my thermostat out, and it turns out 1/3 of the seals of the moving part of the thermostat is missing, just like mad082's n14. The car always took longer than other cars I have driven to warm up. So it was probably wearing out already. The overheating issue I was having before I replaced the water pump must have caused the seals to wear out faster. Just need to wait for the silicon sealer to dry before i can test the new thermostat

thanks guys
