Chris Mc Posted July 5, 2022 Share Posted July 5, 2022 Hi Folks Chris here new to the group I recently purchased 3.0 2007 Alphard, which I'm having problems with one of the heater pipes blew so got to the nearest garage for repair however 2 mile from garage car started to over heat brought it back they said it needed a Thermostat got the thermostat and they returned the car but I think she is still running hot the car gets up to operating temperature in about 5 minutes tops and the needle sits just below the halfway mark, I am not 1005 this is the correct position for it but I thought it usually sat much lower also once I have taken the car out for a drive and I stop she smells hot especially from the passenger side wheel arch where a lot of the pipework is placed I believe. could any of you good folk confirm the position of the needle and should I be smelling the heat. is there any way to tell if she has not been bled properly. many thanks in advance Chris Quote Link to comment Share on other sites More sharing options...

This time of year I would not be surprised with such a quick warm up, the water temp is probably already 15 degrees before you start the engine. Until you become confident I would check the water level every day, engine cold of course. I cannot comment on the 'hot smell' Quote Link to comment Share on other sites More sharing options...
Chris Mc Posted July 5, 2022 Author Share Posted July 5, 2022 Rojie many thanks for the confirmation on the position of the needle, and the quick warm up time, I guess you are right I just need to get my confidence back in the vehicle, I don't know if the smell I stew result of coolant residue when the original pipe gave way, I'm thinking of stripping her down myself just to double check the work carried out, now I have managed to find some schematics re the cooling system. I will keep an eye on it like you said and follow up this post in a couple of days I guess a good 100 mile run should confirm the stability of the coolant system. Many thanks Chris Quote Link to comment Share on other sites More sharing options...
dezufo Posted July 25, 2022 Share Posted July 25, 2022 Chris , for peace of mind you may want to consider fitting a digital temp gauge that way you can see what the actual temp is, I did it to my forester when the head gasket went awol and have now done it to my mnh15 Quote Link to comment Share on other sites More sharing options...
Chris Mc Posted July 26, 2022 Author Share Posted July 26, 2022 Hi Dezufo, got back late last night from a trip and I'm hoping that I now have the problem solved I bought new coolant pipe and replace both lines removing the silly joints made from plastic which failed me in the first place. so I have done about 500 with no issues so far. I would be very interested in fitting a digital temp gauge never done that before so any tips and advice would be much appreciated.

Chris chris have a low coolant alarm fitted thats what i had done so next time water drops to a certain level a led light shows on the dash or if you dont see it a buzzer goes off Quote Link to comment Share on other sites More sharing options...
Chris.ac Posted July 26, 2022 Share Posted July 26, 2022 your previous 'cool' reading was probably down to the thermostat already being faulty, mine sits at just under the halfway mark, even on a several hundred mile commute. Quote Link to comment Share on other sites More sharing options...

Chris Mc Posted July 29, 2022 Author Share Posted July 29, 2022 Guys many thanks for all the helpful suggestions Chris .ac you are probably right re the initial low reading. Picasso I'm looking at options for either fitting the low coolant level or an Aussie device re engine temp that can connect direct to the block or rocker cover head.
