Hey guys got a couple of cooling system related problems...
1. About four days ago the heater stopped blowing hot air when turned on. I know the car should be up to operating temperature as I drive half hour to work, but when I turn the fan on it just blows cold air. I haven't had much time to attempt to figure out what's wrong as I've been doing a lot of overtime at work and don't have a garage to work on it at home, but the heater hoses appear to be ok.
2. On my way to work this morning, I noticed as I was going also through a roadworks zone that the temp. gauge had risen up to 3/4. I hadn't been working the engine hard at all leading up to this (was just cruising at 80kph and it was only 6°C this morning).
I took it easy the test of the way to work (60kph), and after Is parked the car, I popped the bonnet.and felt the radiator hoses. Top was at normal operating temps but the bottom hose and the radiator cap were cold, and the hose when squeezed felt like it had nothing in it.
The engine itself was no where near boiling temp when I felt the rocker covers.
Same thing happenened on the return journey home, and the temperature gauge returned to it's normal position (1/3) as I pulled into my street.
I figure that either the thermostat is blocked (though top hose was at normal operating temps.), or the radiator is blocked (stopping the hot water from heating the bottom hose)???
Any pointers would be much appreciated
