pusher vs puller fan

If I were you........I'd do a search on this forum, in the General, and in this section, on BHG symptoms, and diagnosis.

Oh what the hell.......I need to practice me 2 finger typing skills. (I bet I can hit the 'backspace' button more times than you, and still 'sound' like I know how to type).

It sounds like you need to have a "block test" performed by a shop. Our car's BHG symptoms are as follows....

Stays reasonably cool around town for short trips, and 1-2 hr cool down times. (like going to the movies) But, after a long drive, it can heat up, or not, until you slow back down.

What happens is....(believe me, I went thru it, and have thoroughly researched it out)............

Back at #6 cylinder it gets a hot spot, which then develops a tiny gasket leak into the coolant passage from the combustion chamber. This pressurizes the cooling system to the point of pushing coolant over into the bottle. If it gets a chance to cool down, it will suck the coolant bottle dry, setting on the little orange light on the left of the dash.

I 'baby'd' mine for 3 months until I could get to it.

Valve job.

You can't go more than 16" electric due to space.

A shroud helps pull air from in front of/thru the radiator, and not from the side of the fan.

A thermostat is a good thing to know that its working properly, 180* prefered, but I seriously doubt its your problem.

I don't believe your water pump is bad either. You can check it easily. Drain some coolant out of the radiator, until you are just above the down tubes inside.

Start the car, and let it warm up. The coolant will start to flow. When its all warmed up, the coolant will flow, but if you raise the idle up to about 1000 rpm, you will see the coolant flow more. The pump is good. No flow=blown engine very quickly.

All your symptoms indicate a possible BHG. Get the blocktest.

There's mechanics/technicians, and then there's parts changers.

Don't just start changing parts, as it may not solve any of your problems. Diagnosis first is the RIGHT way.
