1NZ overheating
Hi all, I've been lurking for a while but not posted anything.
I bought an NCP91 Yaris 1.5 about 6 months ago and I've been having a recurring overheating problem. Just after I first got it it overheated to the point where the red coolant light came on and the motor stalled. The dealer I bought it off sent a truck and a loaner car, then came back to me and said because it's been on the lot for so long the coolant was low and the water pump was bad. They replaced the water pump and thermostat, refilled the coolant and sent it back to me. In the last 2 months driving around with the heater off, it'll go for about 30 minutes before the coolant temp gets to 95C and then starts to climb fast. I turn the heater on and blast the fan then the temp comes down to mid 80s and sits there. I've checked the coolant and it's not using much (if any at all) and it stays a good colour. The oil looks good too. No froth or milk. My partner took it out the other day as her car was blocked in and it was pouring with rain. She drove for about 40 minutes without the heater on but did not realise the temp climbing so when she got home while idling in the driveway the red coolant light came on again. She got out of the car and noticed steaming coolant spewing out of the overflow like a running tap. Has anyone had similar experiences? At this stage I am suspect of the new water pump not being new, new thermostat stuck shut, radiator being blocked or worst case scenario the head gasket going out. Any advice? Cheers |
