Hi and hello from the UK
Bit of help / advice please. had an issue earlier this week TJ over heated on way back from work (14miles) stuck in traffic a few times. temperature gauge went up into the red and the check gauges lamp came on. managed to get home and when stopped opened the bonnet (hood) no coolant being expelled but you could hear what could only be described as water boiling from around the thermostat area. Let engine etc cool down over night.
Yesterday i drained all the coolant or as much as i could the coolant had a very slight brown tinge to it but could tell that the antifreeze was present as was orange / red in colour if poured some into a glass jar.
I put fresh water in and a litre of Prestone coolant flush, followed the instructions and ran engine at idle for about 45 minutes, temperature on gauge went to middle (100deg C), UK temp gauges are in centigrade (40, 100, 125) after about 15 minutes of running and then stayed just over the 100 deg C mark.
Switched engine off and could again hear a boiling water sound coming from around the thermostat area.
Due the running at idle i also checked that i had heat coming from the heater vents and had plenty of heat. turning the heater control back down to minimum cool air came from vents. I don't have AC on this TJ.
Not sure if an issue with the thermostat or possibly the water pump, no leaks or noise coming from water pump, or is it the fan clutch ?
TJ had done 61 thousand miles.
Any idea what the boiling sound could be caused by?
I have ordered order a replacement water pump, thermostat, thermostat housing, new hoses, should i also order a new fan clutch as well.
many thanks for reading and any advice offered
Regards
