does anybody know if there is a 180 thermostat out yet for 04 & 05 5.3 chevrolet trucks ?

 

I bought one for my 05 4.8 off ebay. Some guy from the Bronx. It is listed for a 04 - 05 vette and it was 19.95. Got it 2 weeks ago. I'm sure he has more. It is supposed to be a 160* but it runs at a dead on 180*.

thanks for the info,I have ordered two hyptech thermo and neither one fit.I called hyptech and they said they are waiting to see if the 06 trucks use the smaller neck waterpumps before they start building any new stats

 

would this fit an 01 5.3????

 

The new GTO ones work also. I bought mine listed for a GTO.

 

+1 for a '03

What is the difference between the <'03's and '04-up?

 

in 04 the hole the thermostat housing goes in is a fraction smaller this is the same for 05 also,,this will really make u mad because the only way to see this is to drain the fluid and take the housing out and bam it dont fit...

 

I had a few choice words to say when this happend. I ordered an SLP from Summit and it was supposed to fit an 04. They didn't list for and 05 so I gambled. It was the entire water neck with the t-stat made into it. It wouldnt fit in. I had to put it back together with the stock one, then figure out what I needed, then drain it again and there is no easy way to drain it! One hell of a mess.

 

did the one for the gto come with the water neck or was it just hte stat
