Ok so a few days ago my heaters stopped blowing hot but after around 20 minutes of driving they became lukewarm but engine began to overheat.
There was coolant in the radiator but none in the reservoir so filled it back up and car has run fine for a couple of days but this morning the same has happenend again and the reservoir is again empty.

There is no exhaust smoking and no obvious oil/water contamination and the inside of the radiator appears clean so I am hoping it is not the head gasket.

Hopefully it will be just a leak but of course typical just on Christmas :mad:
My local Jap specialist is having a look on Monday

Look for a wet patch under the car or in the footwell. It could be a leak. On the head gasket, it can fail and let oil into engine and/or let water in. You say you see no smoke, but is it cloudy even when the engine is up to temperature?

Ive never been, just wondering what they are like.
Its easy to miss (I drove past it) but they are Jap specialists so made sense, beats taking it to Honda ;)

Car was ready at dinner time and just picked it up.

The coolant pipe to the throttle body had split so was an easy fix (yay).

Was a nice cheap fix right on Christmas.
Jason I can highly recommend Japtech if you need them, they haven't ripped me off, sorted my car this morning like they said and come across as being a very professional outfit.

:D:D:D

Do you know what there hourly rates are?
Not sure as it was not itemised but it came to £27.50 plus VAT and labour was down as 0.5 hours (30 mins).

It cost me more to hire their courtesy car for 3 days :D

It sounds like a themostat valve thats sticking, I had this on my previous car. If you feel the water pipes under the bonnet, you may find one pipe is hot and the other pipe on the other side of the thermostat may be cold. This will cause the car to over heat as the valve may not open to allow water to circulate into the radiator.

If that is the case then the temperature gauge won't rise as the temperature is normally read from the radiator. The culprit was found to be a leaking pipe.

Not the case as the temperature sensor on my Ford was on the Themostate valve housing, it read off the gauge (MAX), maybe Honda's are different?

Surely the radiator would give a false reading, bacause the radiator on a car is designed to cool the coolent, so it should be significantly colder in there, im pretty sure that on all cars the temp sensor is fitted directly into a water jacket surrounding the engine head so it gives a true reading of engine temp

Thanks for all the comments guys but as said it was a leaking pipe all sorted now.
But thanks anyway :D
