EA Heater Problem

Hi,

Im having problems with the heater on my EA CFI, on gas. When the car warms up the heater runs fine, normal heat. However, when i idle in traffic for 5 minutes or so, the heater will go completely stone cold.

Ive changed thermostats, so that isnt the problem, and the heater tap works fine. Also the heater tap will default to open on a loss of vacum, so i dont think its that side, and the tap itself functions fine.

Once im driving down the road again she'll warm back up to normal temp.

This is really annoying, so if anyone has any suggestions, let me know...

Jase

Have u checked your vacuum lines in the engine bay. They might be kinked or partially blocked, not giving enuf vacuum to the heater valve when the vacuum is low while idling. Something to check

When the heater vacum line is disconnected, the tap defaults to open. Hence kinked vacum line = no vacum = full heater.

Any other ideas?

Re: EA Heater Problem

is it at all possible that the heater core/gas convertor are plumbed incorrectly to the bypass lines?

the page at http://www.are.com.au/feat/techt/thermostat.htm describes the bypass outlet as being closed when the engine reaches full operating temperature. i thought there needed to be flow through the bypass to ensure the heater operates?
