heater matrix

Could it also possibly be a low temp thermostat in the engine he might not know about?

[john_petchey]

dont think its the heater matrix as the car isnt over heatin

[david932]

heater matrix doesn't necessary affect the engine temp your confusing it with the rad. the heater matrix is a smaller rad (behind the dash?) to control the cabin temp

the car may not overheat if the heater matrix is partialy blocked,if some water gets through the fan will stop the car from overheating as will the increased efficiency of the new rad :D

I've never seen a low temp stat stop the blowers from blowing hot air.

exactly, water is always flowing through the matrix unlike the rad.

it'll be down to a blocked heater matrix, the copper pipes inside them are of a small bore and can easily get sludged up after years of service. cheap to buy but a pig to replace

more to the point how have you got that sinature picture of your car under every post!!!

Well thats weird. Whenever my car is left running, it warms up to about the third line on the temp gauge, and the heaters are very hot, but when the car is being driven, the temp gauge drops right down, to the first line, and the heaters are only slightly warm!

My guess was that it was the low temp thermostat keeping the engine cooler, is that not right?
