Help Regarding Rb20

[Mr Eps]

hey all, running an rb20DE+T has been this way for about 40xxx kms,

tonight (it's hot) the car seemed to be very... low .. on idle, didn't think much of it, next stop light, car began shuddering and shaking

then up the road began sounding like a complete TRUCK .. not too good.. so i stopped

the engine bay smelled really ... undesirable.. coolant levels were fine, oil levels are fine, coolant TEMP is fine.. engine TEMP is fine... yet.. the head is producing HUGE amounts of heat

let the car cool down completely and had to limp it home

because there was no tow truck that wanted to help me

either way

here's the clues

temp guage at normal

coolant at normal

radiator not hot

oil levels fine

cooler pipes fine

comes onto boost fine

spools up fine

but

makes horrible noises once properly warmed up

producing awful amounts of heat on the head

Radiator not hot at all or normal temp? If the head is really hot and the radiator isnt then maybe coolant isnt flowing properly. Maybe your water pump is gone. The coolant could still appear normal temp if the coolant surounding the temp sensor is not overheating. Just an idea

[Mr Eps]

that would make sense really... radiator was not hot like AT ALL like no heat what so ever even on the cap itself

but in the event of the water pump being stuffed... i had my 100k service done not long ago... like... a few months ago.. and had the water pump replaced then... it's still a brand new pump!!

hot dog... i hate cars..

haha

[Bennett]

Hmm so most likely not pump but ur radiator SHOULD be to hot to touch. Its its not hot at all then i would say there is definately something restricting the flow of your coolant.

[GTR-32U]

could the thermostat have failed restricting coolant flow ? check to see if it works first! Rip out thermostat, Boil a pot of water with thermostat in there. Quickly whip it out to see if its opened up

[cuppas]

+1 thermo check

if the radiator cap was still cold, the thermostat wouldnt have opened...

[Mr Eps]

thanks guys!

love youse aye!

[NZM.031]

sounds very thermostaty...

also has the coolant been bled properly?? maybe has a huge air bubble cruising around the head...

also, where are you checking the coolant level?? in the radiator with the cap off or in the overflow bottle?? and with the engine running or not??

if its making horrible noises when warmed up im thinkin head or head gasket is dying check plugs for evidence of wetness.. pressure test cooling system and look into cylinders to see if any are filling with coolant..

cheers

[Mr Eps]

there's no milky oil

dont you DARE say something is wrong with the head, that would break my heart.. haha!

coolant levels have been checked in both places..

i doubt it would have been bled incorrectly because i had it bled @ kensai garage by roy who is (in my opinion) perth's best most meticulous mechanic

so

will check thermo soon as i get the chance

althoguh

honestly guys... im pretty car savvy, but i also dont mind getting a mechanic

is this a "just do it on a thursday night" job?

or is this a "spend 3 weeks on it and cut up my hands and regret not taking it to a pro in the first place" job

cos seriously i dont have the time needed for that sort of mess =)

[Bennett]

Nothing will take you 6 weeks unless the head needs to come off and you try to do it yourself. Anything else should be able to be completed over a weekend.

[cuppas]

and its really hard to cut yourself on a few bolts and a couple of litres of coolant.

[Mr Eps]

UGHHHHHH!!!!!!

i've gotten the hose off from the housing but there's three bolts which hold the housing to the block

i've gotten 2 bolts off the housing but there's a third one which is not only hidden but also blocked by about 4 different things!!!!

can anyone please provide advice with how to get this FUCKER off???
