After the H/C install my car will get 230* with the A/C running on a hot day These readings are from a scan tool not the guage so I know it"s accurate. Not losing any water so I think head gaskets are ok. On a cooler day in the 70's the temp stays fine and never gets over 205* but these 90* plus days have me reluctant to drive the car Thermostat opens. Before the H/C it used to cool right down when the fans came on now it keeps getting hotter with both running. I think I'll get the radiator flow tested when I get back in town next week. Any other Ideas. I have had it suggested it is the extra timing in the tune but I doubt it could cause it to this extreme

mine gets to 230+ if iidle too long in one place with the ac on these hot gulf coast days. i have a4 and stall to cool too tho. more reasonable temps and i get the same as you do, 205ish

Thanks! Makes me feel a little better The tuner says not to worry about it but I am sometimes stuck in my old school Gen I ways

Anybody else??

Added advance and lean conditions can cause your engine to run a bit hotter. Maybe take out some advance ? What do the plugs and tail pipes look like ?

What temp T-stat are you running ?.. is it a high flow one ? Set the Fans to come on at a lower temp ? Maybe try flushing the system and using some water wetter on the refill and purge air pockets out? Add a external Trans cooler. Make sure your front air dams and spoiler are in good shape to keep air flow into the radiator.

Thanks Man

195* T-Stat OEM Goodwrench
Fans come on at 185*
30,000lb. Hayden cooler
Air dam intact
new dex cool


I am starting to suspect flow issues as the coolant in Rad and recovery tank doesn't seem hot.
Any other H/C cars do this other than me and dab2pds

How about trying a 180* Stat.. with your fans coming on at 185* and the 195*.. You might be able to keep it a little bit cooler. Seem that the Fans would never turn off if it can not cool down to under the 195* Stat...

^^ Heads/Cam install.

Mine did the same & it turned out to be the water pump. It started weeping out about a day after the swap. I threw on a new water pump, upper/lower radiator hoses & thermostat & have been golden every since.

I have a meziere pump, new 160 thermostat, fans turned on low, and only running 26 degrees of timing(more at idle of course, but i'd have to check my hp files). as soon as i turn the ac off and/or get moving the indicated temps go down, it's just hot as **** down here in ms by the gulf

Check for air in the coolant system

If you pull the hose from the head to the throttle body off or the throttle body by pass if you have done that mod and add coolant or water till it comes out of the head that is the highest point and all of the air should purge when filling up to that level... you may have a little air in your system..good luck with it...

i would bet you have some air in there...plus why not get a 160 stat...

I also think it's most likely air in the system. There is a procedure to purge it. Mine never gets over about 195, even when sitting in traffic at 95 degrees outside and running the air.

You dont have flow issues, drop in a 160 stat then have the fans reprogrammed for that rating. youll see 180 temps when cruising, 205 if your stuck in traffic on a hot day

Thats what ECS did on my H/C and its been like that for 4 years with no issues.

+3 on air in the system. Let the car cool down and take the rad cap off. Start her up, and rev the engine up and down to kick the bubbles out. Keep the coolant level to the top of the radiator neck as you rev, so no more air gets in the system.

I've done this when draining the radiator on my car three times, an on a h/c install once - works like a charm.
