Temp gauge failure/burning plastic smell from under front hood? (Page 3/3) chaotichamster9 JUN 23, 06:28 PM Yeah that makes sense with the A/C oil being on those lines, would that cause a burning smell? Going to top off the coolant, do you fill from both the front radiator cap AND thermostat cap out back in these cars or only at one spot? Going to order a new coolant bottle cap too so that fluid isn’t getting blown around. fierosound JUN 24, 10:55 AM quote Originally posted by chaotichamster9: Yeah that makes sense with the A/C oil being on those lines, would that cause a burning smell?

Going to order a new coolant bottle cap too so that fluid isn’t getting blown around. To fill cooling system, pour coolant in the thermostat housing until radiator is full. Then cap radiator and finish filling at thermostat housing. To top off if system has lost some coolant, fill at thermostat housing. I never liked factory coolant reservoir cap. Coolant splashes out when it sloshed around in tank. I'm using Dorman cap like this instead (NOT SURE if this is correct part number) Check the parts in Help section at your local auto parts store. https://www.amazon.com/Dorm...nt-Cap/dp/B000C5G8CM olejoedad JUN 24, 01:06 PM The coolant bottle cap is vented, a replacement cap must also be vented. chaotichamster9 JUN 24, 05:13 PM Got the new reservoir bottle cap, going to change oil today. I have a Mobil 1 M1-201A, will that work? I see the M1-201 has been recommended, what’s the difference from the “A” one? Putting 5w30 Mobil 1 advances full synthetic oil as well. chaotichamster9 JUN 24, 07:12 PM Found the source of the burning smell!! Was driving to the oil change and saw smoke coming out of the passenger front tire. Checked and the rotor appears to be gouged. Looks like I’ll need a new rotor caliper and brake pads.
