I don't know what it's called. It's a plastic apron attached to front top of radiator and comes down to and tucks under inside bottom of the front bumper. It sort of directs incoming air to the radiator.

Default Re: High coolant temp

Has anybody tried to restict the flow in the coolant bypass line? Without blowing out the rad (ha). I read writings from people who had MH do this as a last resort type of thing that fixed high temps once and for all.
Saw pics of somwone who actult put in a shut off valve so he could set it for best results, Traffic, high revs ect.

Yes! That was one of the main problems with my 94, overheating. I sent it to Mark (for that and other work). He did his normal radiator service ......then put a washer type affair in the by pass line at the T- housing. Instant fix. The car runs in the low 190's.....down from 220/230 before the ''fix''.

No. That's not the one.
The apron I am talking about separates radiator intake area from the inside of the front bumper.
Next time I get the car on the lift I will take a pic.

hey, when I changed my kn filter last week, I found the same one in your pic, but the radius part at the top was facing down to the very nose of the filter housing and the slotted part was coving a 1/4 of the top of filter housing, I thought as if to prevent water splashing into the filter. I put it back the same way, I didnt drive it today but will take pic of it tonite. hell now... I'm not sure if it is placed correctly or not.

This may be the same piece. It's just that "perspective" of the picture amy be making it difficult for me to identify. Post a pic and perhaps I can make a better sense of it.

I drove the Z into work and temp is holding good. Never went over 208. Cruising temp was 201 in 5th.

Driving back home will be the true test since it will be around 90. It was 78 this morning.

I'm not able to follow the discussion as I can't open the link as presented. However, this appears to be a picture of a thermostat. Mark Haibeck installed something what he refered to as ''a washer looking item'' to restrict the water flow through the by pass. We had talked over the phone and he was asking if he could use my car as a little experment. He related that he had worked on other Z's with the same problem but wanted to try this on mine. At the time I had him installed a new OEM thermostat and do his radiator service. The end result was a drastic reduction in temps.

You must replace the asterisks in the link with "that other forum's name". For some reason links to the other forum are masked here....
